Class Overview

Displays text to the user and optionally allows them to edit it. A TextView is a complete text editor, however the basic class is configured to not allow editing; see EditText for a subclass that configures the text view for editing.

To allow users to copy some or all of the TextView's value and paste it somewhere else, set the XML attribute android:textIsSelectable to "true" or call setTextIsSelectable(true). The textIsSelectable flag allows users to make selection gestures in the TextView, which in turn triggers the system's built-in copy/paste controls.

android:imeOptions

Additional features you can enable in an IME associated with an editor to improve the integration with your application. The constants here correspond to those defined by imeOptions.

Must be one or more (separated by '|') of the following constant values.

Constant	Value	Description
`normal`	0x00000000	There are no special semantics associated with this editor.
`actionUnspecified`	0x00000000	There is no specific action associated with this editor, let the editor come up with its own if it can. Corresponds to `IME_NULL`.
`actionNone`	0x00000001	This editor has no action associated with it. Corresponds to `IME_ACTION_NONE`.
`actionGo`	0x00000002	The action key performs a "go" operation to take the user to the target of the text they typed. Typically used, for example, when entering a URL. Corresponds to `IME_ACTION_GO`.
`actionSearch`	0x00000003	The action key performs a "search" operation, taking the user to the results of searching for the text the have typed (in whatever context is appropriate). Corresponds to `IME_ACTION_SEARCH`.
`actionSend`	0x00000004	The action key performs a "send" operation, delivering the text to its target. This is typically used when composing a message. Corresponds to `IME_ACTION_SEND`.
`actionNext`	0x00000005	The action key performs a "next" operation, taking the user to the next field that will accept text. Corresponds to `IME_ACTION_NEXT`.
`actionDone`	0x00000006	The action key performs a "done" operation, closing the soft input method. Corresponds to `IME_ACTION_DONE`.
`actionPrevious`	0x00000007	The action key performs a "previous" operation, taking the user to the previous field that will accept text. Corresponds to `IME_ACTION_PREVIOUS`.
`flagNoFullscreen`	0x2000000	Used to request that the IME never go into fullscreen mode. Applications need to be aware that the flag is not a guarantee, and not all IMEs will respect it. Corresponds to `IME_FLAG_NO_FULLSCREEN`.
`flagNavigatePrevious`	0x4000000	Like flagNavigateNext, but specifies there is something interesting that a backward navigation can focus on. If the user selects the IME's facility to backward navigate, this will show up in the application as an actionPrevious at `InputConnection.performEditorAction(int)`. Corresponds to `IME_FLAG_NO_FULLSCREEN`.
`flagNavigateNext`	0x8000000	Used to specify that there is something interesting that a forward navigation can focus on. This is like using actionNext, except allows the IME to be multiline (with an enter key) as well as provide forward navigation. Note that some IMEs may not be able to do this, especially when running on a small screen where there is little space. In that case it does not need to present a UI for this option. Like actionNext, if the user selects the IME's facility to forward navigate, this will show up in the application at `InputConnection.performEditorAction(int)`. Corresponds to `IME_FLAG_NAVIGATE_NEXT`.
`flagNoExtractUi`	0x10000000	Used to specify that the IME does not need to show its extracted text UI. For input methods that may be fullscreen, often when in landscape mode, this allows them to be smaller and let part of the application be shown behind. Though there will likely be limited access to the application available from the user, it can make the experience of a (mostly) fullscreen IME less jarring. Note that when this flag is specified the IME may not be set up to be able to display text, so it should only be used in situations where this is not needed. Corresponds to `IME_FLAG_NO_EXTRACT_UI`.
`flagNoAccessoryAction`	0x20000000	Used in conjunction with a custom action, this indicates that the action should not be available as an accessory button when the input method is full-screen. Note that by setting this flag, there can be cases where the action is simply never available to the user. Setting this generally means that you think showing text being edited is more important than the action you have supplied. Corresponds to `IME_FLAG_NO_ACCESSORY_ACTION`.
`flagNoEnterAction`	0x40000000	Used in conjunction with a custom action, this indicates that the action should not be available in-line as a replacement for the "enter" key. Typically this is because the action has such a significant impact or is not recoverable enough that accidentally hitting it should be avoided, such as sending a message. Note that `TextView` will automatically set this flag for you on multi-line text views. Corresponds to `IME_FLAG_NO_ENTER_ACTION`.
`flagForceAscii`	0x80000000	Used to request that the IME should be capable of inputting ASCII characters. The intention of this flag is to ensure that the user can type Roman alphabet characters in a `TextView` used for, typically, account ID or password input. It is expected that IMEs normally are able to input ASCII even without being told so (such IMEs already respect this flag in a sense), but there could be some cases they aren't when, for instance, only non-ASCII input languagaes like Arabic, Greek, Hebrew, Russian are enabled in the IME. Applications need to be aware that the flag is not a guarantee, and not all IMEs will respect it. However, it is strongly recommended for IME authors to respect this flag especially when their IME could end up with a state that has only non-ASCII input languages enabled. Corresponds to `IME_FLAG_FORCE_ASCII`.

This corresponds to the global attribute resource symbol imeOptions.

public boolean hasOverlappingRendering ()

Added in API level 16

Returns whether this View has content which overlaps.

This function, intended to be overridden by specific View types, is an optimization when alpha is set on a view. If rendering overlaps in a view with alpha < 1, that view is drawn to an offscreen buffer and then composited into place, which can be expensive. If the view has no overlapping rendering, the view can draw each primitive with the appropriate alpha value directly. An example of overlapping rendering is a TextView with a background image, such as a Button. An example of non-overlapping rendering is a TextView with no background, or an ImageView with only the foreground image. The default implementation returns true; subclasses should override if they have cases which can be optimized.

The current implementation of the saveLayer and saveLayerAlpha methods in Canvas necessitates that a View return true if it uses the methods internally without passing the CLIP_TO_LAYER_SAVE_FLAG.

Returns

true if the content in this view might overlap, false otherwise.

public boolean hasSelection ()

Added in API level 3

Returns whether this text view is a current input method target. The default implementation just checks with InputMethodManager.

public boolean isSuggestionsEnabled ()

Added in API level 14

Return whether or not suggestions are enabled on this TextView. The suggestions are generated by the IME or by the spell checker as the user types. This is done by adding SuggestionSpans to the text. When suggestions are enabled (default), this list of suggestions will be displayed when the user asks for them on these parts of the text. This value depends on the inputType of this TextView. The class of the input type must be TYPE_CLASS_TEXT. In addition, the type variation must be one of TYPE_TEXT_VARIATION_NORMAL, TYPE_TEXT_VARIATION_EMAIL_SUBJECT, TYPE_TEXT_VARIATION_LONG_MESSAGE, TYPE_TEXT_VARIATION_SHORT_MESSAGE or TYPE_TEXT_VARIATION_WEB_EDIT_TEXT. And finally, the TYPE_TEXT_FLAG_NO_SUGGESTIONS flag must not be set.

Returns

true if the suggestions popup window is enabled, based on the inputType.

public boolean isTextSelectable ()

Added in API level 11

Returns

True if the cursor was actually moved, false otherwise.

public void onBeginBatchEdit ()

Added in API level 3

Called by the framework in response to a request to begin a batch of edit operations through a call to link beginBatchEdit().

public boolean onCheckIsTextEditor ()

Added in API level 3

Check whether the called view is a text editor, in which case it would make sense to automatically display a soft input window for it. Subclasses should override this if they implement onCreateInputConnection(EditorInfo) to return true if a call on that method would return a non-null InputConnection, and they are really a first-class editor that the user would normally start typing on when the go into a window containing your view.

The default implementation always returns false. This does not mean that its onCreateInputConnection(EditorInfo) will not be called or the user can not otherwise perform edits on your view; it is just a hint to the system that this is not the primary purpose of this view.

Returns

Returns true if this view is a text editor, else false.

public void onCommitCompletion (CompletionInfo text)

Added in API level 3

Called by the framework in response to a text completion from the current input method, provided by it calling InputConnection.commitCompletion(). The default implementation does nothing; text views that are supporting auto-completion should override this to do their desired behavior.

Parameters

text	The auto complete text the user has selected.

public void onCommitCorrection (CorrectionInfo info)

Added in API level 11

Called by the framework in response to a text auto-correction (such as fixing a typo using a a dictionnary) from the current input method, provided by it calling commitCorrection(CorrectionInfo) InputConnection.commitCorrection()}. The default implementation flashes the background of the corrected word to provide feedback to the user.

Parameters

info	The auto correct info about the text that was corrected.

public InputConnection onCreateInputConnection (EditorInfo outAttrs)

Added in API level 3

Create a new InputConnection for an InputMethod to interact with the view. The default implementation returns null, since it doesn't support input methods. You can override this to implement such support. This is only needed for views that take focus and text input.

When implementing this, you probably also want to implement onCheckIsTextEditor() to indicate you will return a non-null InputConnection.

Also, take good care to fill in the EditorInfo object correctly and in its entirety, so that the connected IME can rely on its values. For example, initialSelStart and initialSelEnd members must be filled in with the correct cursor position for IMEs to work correctly with your application.

Parameters

outAttrs	Fill in with attribute information about the connection.

public boolean onDragEvent (DragEvent event)

Added in API level 11

Handles drag events sent by the system following a call to startDrag().

When the system calls this method, it passes a DragEvent object. A call to getAction() returns one of the action type constants defined in DragEvent. The method uses these to determine what is happening in the drag and drop operation.

Parameters

event	The `DragEvent` sent by the system. The `getAction()` method returns an action type constant defined in DragEvent, indicating the type of drag event represented by this object.

Returns

true if the method was successful, otherwise false.
The method should return true in response to an action type of ACTION_DRAG_STARTED to receive drag events for the current operation.

The method should also return true in response to an action type of ACTION_DROP if it consumed the drop, or false if it didn't.

public void onEditorAction (int actionCode)

Added in API level 3

Called when an attached input method calls InputConnection.performEditorAction() for this text view. The default implementation will call your action listener supplied to setOnEditorActionListener(TextView.OnEditorActionListener), or perform a standard operation for EditorInfo.IME_ACTION_NEXT, EditorInfo.IME_ACTION_PREVIOUS, or EditorInfo.IME_ACTION_DONE.

For backwards compatibility, if no IME options have been set and the text view would not normally advance focus on enter, then the NEXT and DONE actions received here will be turned into an enter key down/up pair to go through the normal key handling.

Parameters

actionCode	The code of the action being performed.

public void onEndBatchEdit ()

Added in API level 3

Called by the framework in response to a request to end a batch of edit operations through a call to link endBatchEdit().

public void onFinishTemporaryDetach ()

Added in API level 3

Called after onStartTemporaryDetach() when the container is done changing the view.

public boolean onGenericMotionEvent (MotionEvent event)

Added in API level 12

Implement this method to handle generic motion events.

Generic motion events describe joystick movements, mouse hovers, track pad touches, scroll wheel movements and other input events. The source of the motion event specifies the class of input that was received. Implementations of this method must examine the bits in the source before processing the event. The following code example shows how this is done.

Generic motion events with source class SOURCE_CLASS_POINTER are delivered to the view under the pointer. All other generic motion events are delivered to the focused view.

 public boolean onGenericMotionEvent(MotionEvent event) {
     if (event.isFromSource(InputDevice.SOURCE_CLASS_JOYSTICK)) {
         if (event.getAction() == MotionEvent.ACTION_MOVE) {
             // process the joystick movement...
             return true;
         }
     }
     if (event.isFromSource(InputDevice.SOURCE_CLASS_POINTER)) {
         switch (event.getAction()) {
             case MotionEvent.ACTION_HOVER_MOVE:
                 // process the mouse hover movement...
                 return true;
             case MotionEvent.ACTION_SCROLL:
                 // process the scroll wheel movement...
                 return true;
         }
     }
     return super.onGenericMotionEvent(event);
 }

Parameters

event	The generic motion event being processed.

Returns

True if the event was handled, false otherwise.

public boolean onKeyDown (int keyCode, KeyEvent event)

Added in API level 1

Default implementation of KeyEvent.Callback.onKeyDown(): perform press of the view when KEYCODE_DPAD_CENTER or KEYCODE_ENTER is released, if the view is enabled and clickable.

Key presses in software keyboards will generally NOT trigger this listener, although some may elect to do so in some situations. Do not rely on this to catch software key presses.

Parameters

keyCode	A key code that represents the button pressed, from `KeyEvent`.
event	The KeyEvent object that defines the button action.

Returns

If you handled the event, return true. If you want to allow the event to be handled by the next receiver, return false.

public boolean onKeyMultiple (int keyCode, int repeatCount, KeyEvent event)

Added in API level 1

Default implementation of KeyEvent.Callback.onKeyMultiple(): always returns false (doesn't handle the event).

Key presses in software keyboards will generally NOT trigger this listener, although some may elect to do so in some situations. Do not rely on this to catch software key presses.

Parameters

keyCode	A key code that represents the button pressed, from `KeyEvent`.
repeatCount	The number of times the action was made.
event	The KeyEvent object that defines the button action.

Returns

If you handled the event, return true. If you want to allow the event to be handled by the next receiver, return false.

public boolean onKeyPreIme (int keyCode, KeyEvent event)

Added in API level 3

Handle a key event before it is processed by any input method associated with the view hierarchy. This can be used to intercept key events in special situations before the IME consumes them; a typical example would be handling the BACK key to update the application's UI instead of allowing the IME to see it and close itself.

Parameters

keyCode	The value in event.getKeyCode().
event	Description of the key event.

Returns

If you handled the event, return true. If you want to allow the event to be handled by the next receiver, return false.

public boolean onKeyShortcut (int keyCode, KeyEvent event)

Added in API level 1

Called on the focused view when a key shortcut event is not handled. Override this method to implement local key shortcuts for the View. Key shortcuts can also be implemented by setting the shortcut property of menu items.

Parameters

keyCode	The value in event.getKeyCode().
event	Description of the key event.

Returns

If you handled the event, return true. If you want to allow the event to be handled by the next receiver, return false.

public boolean onKeyUp (int keyCode, KeyEvent event)

Added in API level 1

Default implementation of KeyEvent.Callback.onKeyUp(): perform clicking of the view when KEYCODE_DPAD_CENTER or KEYCODE_ENTER is released.

Key presses in software keyboards will generally NOT trigger this listener, although some may elect to do so in some situations. Do not rely on this to catch software key presses.

Parameters

keyCode	A key code that represents the button pressed, from `KeyEvent`.
event	The KeyEvent object that defines the button action.

Returns

If you handled the event, return true. If you want to allow the event to be handled by the next receiver, return false.

public boolean onPreDraw ()

Added in API level 1

Callback method to be invoked when the view tree is about to be drawn. At this point, all views in the tree have been measured and given a frame. Clients can use this to adjust their scroll bounds or even to request a new layout before drawing occurs.

Returns

Return true to proceed with the current drawing pass, or false to cancel.

public boolean onPrivateIMECommand (String action, Bundle data)

Added in API level 3

Called by the framework in response to a private command from the current method, provided by it calling InputConnection.performPrivateCommand().

Parameters

action	The action name of the command.
data	Any additional data for the command. This may be null.

Returns

Return true if you handled the command, else false.

public void onProvideStructure (ViewStructure structure)

Added in API level 23

Called when assist structure is being retrieved from a view as part of Activity.onProvideAssistData.

Parameters

structure	Fill in with structured view data. The default implementation fills in all data that can be inferred from the view itself.

public void onRestoreInstanceState (Parcelable state)

Added in API level 1

Hook allowing a view to re-apply a representation of its internal state that had previously been generated by onSaveInstanceState(). This function will never be called with a null state.

Parameters

state	The frozen state that had previously been returned by `onSaveInstanceState()`.

public void onRtlPropertiesChanged (int layoutDirection)

Added in API level 17

Called when any RTL property (layout direction or text direction or text alignment) has been changed. Subclasses need to override this method to take care of cached information that depends on the resolved layout direction, or to inform child views that inherit their layout direction. The default implementation does nothing.

Parameters

layoutDirection	the direction of the layout

public Parcelable onSaveInstanceState ()

Added in API level 1

Hook allowing a view to generate a representation of its internal state that can later be used to create a new instance with that same state. This state should only contain information that is not persistent or can not be reconstructed later. For example, you will never store your current position on screen because that will be computed again when a new instance of the view is placed in its view hierarchy.

Some examples of things you may store here: the current cursor position in a text view (but usually not the text itself since that is stored in a content provider or other persistent storage), the currently selected item in a list view.

Returns

Returns a Parcelable object containing the view's current dynamic state, or null if there is nothing interesting to save. The default implementation returns null.

public void onScreenStateChanged (int screenState)

Added in API level 16

This method is called whenever the state of the screen this view is attached to changes. A state change will usually occurs when the screen turns on or off (whether it happens automatically or the user does it manually.)

Parameters

screenState	The new state of the screen. Can be either `SCREEN_STATE_ON` or `SCREEN_STATE_OFF`

public void onStartTemporaryDetach ()

Added in API level 3

This is called when a container is going to temporarily detach a child, with ViewGroup.detachViewFromParent. It will either be followed by onFinishTemporaryDetach() or onDetachedFromWindow() when the container is done.

public boolean onTextContextMenuItem (int id)

Added in API level 3

Called when a context menu option for the text view is selected. Currently this will be one of selectAll, cut, copy, paste or shareText.

Returns

true if the context menu item action was performed.

public boolean onTouchEvent (MotionEvent event)

Added in API level 1

Implement this method to handle touch screen motion events.

If this method is used to detect click actions, it is recommended that the actions be performed by implementing and calling performClick(). This will ensure consistent system behavior, including:

obeying click sound preferences
dispatching OnClickListener calls
handling ACTION_CLICK when accessibility features are enabled

Parameters

event	The motion event.

Returns

True if the event was handled, false otherwise.

public boolean onTrackballEvent (MotionEvent event)

Added in API level 1

Implement this method to handle trackball motion events. The relative movement of the trackball since the last event can be retrieve with MotionEvent.getX() and MotionEvent.getY(). These are normalized so that a movement of 1 corresponds to the user pressing one DPAD key (so they will often be fractional values, representing the more fine-grained movement information available from a trackball).

Parameters

event	The motion event.

Returns

True if the event was handled, false otherwise.

public void onWindowFocusChanged (boolean hasWindowFocus)

Added in API level 1

Called when the window containing this view gains or loses focus. Note that this is separate from view focus: to receive key events, both your view and its window must have focus. If a window is displayed on top of yours that takes input focus, then your own window will lose focus but the view focus will remain unchanged.

Parameters

hasWindowFocus	True if the window containing this view now has focus, false otherwise.

public boolean performLongClick ()

Added in API level 1

Call this view's OnLongClickListener, if it is defined. Invokes the context menu if the OnLongClickListener did not consume the event.

Returns

True if one of the above receivers consumed the event, false otherwise.

public void removeTextChangedListener (TextWatcher watcher)

Added in API level 1

android:drawablePadding

public void setCompoundDrawableTintList (ColorStateList tint)

Added in API level 23

Applies a tint to the compound drawables. Does not modify the current tint mode, which is SRC_IN by default.

Related XML Attributes

android:drawableTint

Parameters

tint	the tint to apply, may be `null` to clear tint

public void setCompoundDrawableTintMode (PorterDuff.Mode tintMode)

Related XML Attributes

android:cursorVisible

public void setCustomInsertionActionModeCallback (ActionMode.Callback actionModeCallback)

Added in API level 23

If provided, this ActionMode.Callback will be used to create the ActionMode when text insertion is initiated in this View. The standard implementation populates the menu with a subset of Select All, Paste and Replace actions, depending on what this View supports.

A custom implementation can add new entries in the default menu in its onPrepareActionMode(android.view.ActionMode, android.view.Menu) method. The default actions can also be removed from the menu using removeItem(int) and passing selectAll, paste or replaceText ids as parameters.

Returning false from onCreateActionMode(android.view.ActionMode, android.view.Menu) will prevent the action mode from being started.

Action click events should be handled by the custom implementation of onActionItemClicked(android.view.ActionMode, android.view.MenuItem).

Note that text insertion mode is not started when a TextView receives focus and the selectAllOnFocus flag has been set.

public void setCustomSelectionActionModeCallback (ActionMode.Callback actionModeCallback)

Added in API level 11

If provided, this ActionMode.Callback will be used to create the ActionMode when text selection is initiated in this View.

The standard implementation populates the menu with a subset of Select All, Cut, Copy, Paste, Replace and Share actions, depending on what this View supports.

A custom implementation can add new entries in the default menu in its onPrepareActionMode(ActionMode, android.view.Menu) method. The default actions can also be removed from the menu using removeItem(int) and passing selectAll, cut, copy, paste, replaceText or shareText ids as parameters.

Returning false from onCreateActionMode(ActionMode, android.view.Menu) will prevent the action mode from being started.

Action click events should be handled by the custom implementation of onActionItemClicked(ActionMode, android.view.MenuItem).

Note that text selection mode is not started when a TextView receives focus and the selectAllOnFocus flag has been set. The content is highlighted in that case, to allow for quick replacement.

public final void setEditableFactory (Editable.Factory factory)

Added in API level 1

Sets the Factory used to create new Editables.

public void setElegantTextHeight (boolean elegant)

Added in API level 21

Set the TextView's elegant height metrics flag. This setting selects font variants that have not been compacted to fit Latin-based vertical metrics, and also increases top and bottom bounds to provide more space.

Related XML Attributes

android:elegantTextHeight

Parameters

elegant	set the paint's elegant metrics flag.

public void setEllipsize (TextUtils.TruncateAt where)

Added in API level 1

Causes words in the text that are longer than the view is wide to be ellipsized instead of broken in the middle. You may also want to setSingleLine() or setHorizontallyScrolling(boolean) to constrain the text to a single line. Use null to turn off ellipsizing. If setMaxLines(int) has been used to set two or more lines, only END and MARQUEE are supported (other ellipsizing types will not do anything).

public void setError (CharSequence error, Drawable icon)

Added in API level 1

Sets the right-hand compound drawable of the TextView to the specified icon and sets an error message that will be displayed in a popup when the TextView has focus. The icon and error message will be reset to null when any key events cause changes to the TextView's text. The drawable must already have had setBounds(Rect) set on it. If the error is null, the error message will be cleared (and you should provide a null icon as well).

public void setInputType (int type)

Added in API level 3

Set the type of the content with a constant as defined for inputType. This will take care of changing the key listener, by calling setKeyListener(KeyListener), to match the given content type. If the given content type is TYPE_NULL then a soft keyboard will not be displayed for this text view. Note that the maximum number of displayed lines (see setMaxLines(int)) will be modified if you change the TYPE_TEXT_FLAG_MULTI_LINE flag of the input type.

Related XML Attributes

android:inputType

public void setKeyListener (KeyListener input)

Added in API level 1

Sets the key listener to be used with this TextView. This can be null to disallow user input. Note that this method has significant and subtle interactions with soft keyboards and other input method: see KeyListener.getContentType() for important details. Calling this method will replace the current content type of the text view with the content type returned by the key listener.

Be warned that if you want a TextView with a key listener or movement method not to be focusable, or if you want a TextView without a key listener or movement method to be focusable, you must call setFocusable(boolean) again after calling this to get the focusability back the way you want it.

Added in API level 1

Sets line spacing for this TextView. Each line will have its height multiplied by mult and have add added to it.

Added in API level 3

Set a special listener to be called when an action is performed on the text view. This will be called when the enter key is pressed, or when an action supplied to the IME is selected by the user. Setting this means that the normal hard key event will not insert a newline into the text view, even if it is multi-line; holding down the ALT modifier will, however, allow the user to insert a newline character.

public void setPadding (int left, int top, int right, int bottom)

Added in API level 1

Sets the padding. The view may add on the space required to display the scrollbars, depending on the style and visibility of the scrollbars. So the values returned from getPaddingLeft(), getPaddingTop(), getPaddingRight() and getPaddingBottom() may be different from the values set in this call.

public void setTextIsSelectable (boolean selectable)

Added in API level 11

Sets whether the content of this view is selectable by the user. The default is false, meaning that the content is not selectable.

When you use a TextView to display a useful piece of information to the user (such as a contact's address), make it selectable, so that the user can select and copy its content. You can also use set the XML attribute TextView_textIsSelectable to "true".

When you call this method to set the value of textIsSelectable, it sets the flags focusable, focusableInTouchMode, clickable, and longClickable to the same value. These flags correspond to the attributes android:focusable, android:focusableInTouchMode, android:clickable, and android:longClickable. To restore any of these flags to a state you had set previously, call one or more of the following methods: setFocusable(), setFocusableInTouchMode(), setClickable() or setLongClickable().

Parameters

selectable	Whether the content of this TextView should be selectable.

Returns the strength, or intensity, of the left faded edge. The strength is a value between 0.0 (no fade) and 1.0 (full fade). The default implementation returns 0.0 or 1.0 but no value in between. Subclasses should override this method to provide a smoother fade transition when scrolling occurs.

Returns

the intensity of the left fade as a float between 0.0f and 1.0f

protected int getLeftPaddingOffset ()

Added in API level 2

Amount by which to extend the left fading region. Called only when isPaddingOffsetRequired() returns true.

Returns

The left padding offset in pixels.

protected float getRightFadingEdgeStrength ()

Added in API level 1

Returns the strength, or intensity, of the right faded edge. The strength is a value between 0.0 (no fade) and 1.0 (full fade). The default implementation returns 0.0 or 1.0 but no value in between. Subclasses should override this method to provide a smoother fade transition when scrolling occurs.

Returns

the intensity of the right fade as a float between 0.0f and 1.0f

protected int getRightPaddingOffset ()

Added in API level 2

Amount by which to extend the right fading region. Called only when isPaddingOffsetRequired() returns true.

Returns

The right padding offset in pixels.

protected int getTopPaddingOffset ()

Added in API level 2

Amount by which to extend the top fading region. Called only when isPaddingOffsetRequired() returns true.

Returns

The top padding offset in pixels.

protected boolean isPaddingOffsetRequired ()

Added in API level 2

If the View draws content inside its padding and enables fading edges, it needs to support padding offsets. Padding offsets are added to the fading edges to extend the length of the fade so that it covers pixels drawn inside the padding. Subclasses of this class should override this method if they need to draw content inside the padding.

Returns

True if padding offset must be applied, false otherwise.

protected void onAttachedToWindow ()

Added in API level 1

This is called when the view is attached to a window. At this point it has a Surface and will start drawing. Note that this function is guaranteed to be called before onDraw(android.graphics.Canvas), however it may be called any time before the first onDraw -- including before or after onMeasure(int, int).

protected void onConfigurationChanged (Configuration newConfig)

Added in API level 8

Called when the current configuration of the resources being used by the application have changed. You can use this to decide when to reload resources that can changed based on orientation and other configuration characteristics. You only need to use this if you are not relying on the normal Activity mechanism of recreating the activity instance upon a configuration change.

Parameters

newConfig	The new resource configuration.

protected int[] onCreateDrawableState (int extraSpace)

Added in API level 1

Generate the new Drawable state for this view. This is called by the view system when the cached Drawable state is determined to be invalid. To retrieve the current state, you should use getDrawableState().

Parameters

extraSpace	if non-zero, this is the number of extra entries you would like in the returned array in which you can place your own states.

Returns

Returns an array holding the current Drawable state of the view.

protected void onDraw (Canvas canvas)

Added in API level 1

Implement this to do your drawing.

Parameters

canvas	the canvas on which the background will be drawn

protected void onFocusChanged (boolean focused, int direction, Rect previouslyFocusedRect)

Added in API level 1

Called by the view system when the focus state of this view changes. When the focus change event is caused by directional navigation, direction and previouslyFocusedRect provide insight into where the focus is coming from. When overriding, be sure to call up through to the super class so that the standard focus handling will occur.

Parameters

focused	True if the View has focus; false otherwise.
direction	The direction focus has moved when requestFocus() is called to give this view focus. Values are `FOCUS_UP`, `FOCUS_DOWN`, `FOCUS_LEFT`, `FOCUS_RIGHT`, `FOCUS_FORWARD`, or `FOCUS_BACKWARD`. It may not always apply, in which case use the default.
previouslyFocusedRect	The rectangle, in this view's coordinate system, of the previously focused view. If applicable, this will be passed in as finer grained information about where the focus is coming from (in addition to direction). Will be `null` otherwise.

protected void onLayout (boolean changed, int left, int top, int right, int bottom)

Added in API level 1

Called from layout when this view should assign a size and position to each of its children. Derived classes with children should override this method and call layout on each of their children.

Parameters

changed	This is a new size or position for this view
left	Left position, relative to parent
top	Top position, relative to parent
right	Right position, relative to parent
bottom	Bottom position, relative to parent

protected void onMeasure (int widthMeasureSpec, int heightMeasureSpec)

Added in API level 1

Measure the view and its content to determine the measured width and the measured height. This method is invoked by measure(int, int) and should be overridden by subclasses to provide accurate and efficient measurement of their contents.

CONTRACT: When overriding this method, you must call setMeasuredDimension(int, int) to store the measured width and height of this view. Failure to do so will trigger an IllegalStateException, thrown by measure(int, int). Calling the superclass' onMeasure(int, int) is a valid use.

The base class implementation of measure defaults to the background size, unless a larger size is allowed by the MeasureSpec. Subclasses should override onMeasure(int, int) to provide better measurements of their content.

If this method is overridden, it is the subclass's responsibility to make sure the measured height and width are at least the view's minimum height and width (getSuggestedMinimumHeight() and getSuggestedMinimumWidth()).

Parameters

widthMeasureSpec	horizontal space requirements as imposed by the parent. The requirements are encoded with `View.MeasureSpec`.
heightMeasureSpec	vertical space requirements as imposed by the parent. The requirements are encoded with `View.MeasureSpec`.

protected void onScrollChanged (int horiz, int vert, int oldHoriz, int oldVert)

Added in API level 1

This is called in response to an internal scroll in this view (i.e., the view scrolled its own contents). This is typically as a result of scrollBy(int, int) or scrollTo(int, int) having been called.

Parameters

horiz	Current horizontal scroll origin.
vert	Current vertical scroll origin.
oldHoriz	Previous horizontal scroll origin.
oldVert	Previous vertical scroll origin.

protected void onSelectionChanged (int selStart, int selEnd)

Added in API level 3

This method is called when the selection has changed, in case any subclasses would like to know.

Parameters

selStart	The new selection start location.
selEnd	The new selection end location.

protected void onTextChanged (CharSequence text, int start, int lengthBefore, int lengthAfter)

Added in API level 1

This method is called when the text is changed, in case any subclasses would like to know. Within text, the lengthAfter characters beginning at start have just replaced old text that had length lengthBefore. It is an error to attempt to make changes to text from this callback.

Parameters

text	The text the TextView is displaying
start	The offset of the start of the range of the text that was modified
lengthBefore	The length of the former text that has been replaced
lengthAfter	The length of the replacement modified text

protected void onVisibilityChanged (View changedView, int visibility)

Added in API level 8

Called when the visibility of the view or an ancestor of the view has changed.

Parameters

changedView	The view whose visibility changed. May be `this` or an ancestor view.
visibility	The new visibility, one of `VISIBLE`, `INVISIBLE` or `GONE`.

protected boolean setFrame (int l, int t, int r, int b)

Added in API level 1

Assign a size and position to this view. This is called from layout.

Parameters

l	Left position, relative to parent
t	Top position, relative to parent
r	Right position, relative to parent
b	Bottom position, relative to parent

Returns

true if the new size and position are different than the previous ones

protected boolean verifyDrawable (Drawable who)

Added in API level 1

If your view subclass is displaying its own Drawable objects, it should override this function and return true for any Drawable it is displaying. This allows animations for those drawables to be scheduled.

Be sure to call through to the super class when overriding this function.

Parameters

who	The Drawable to verify. Return true if it is one you are displaying, else return the result of calling through to the super class.

Returns

boolean If true than the Drawable is being displayed in the view; else false and it is not allowed to animate.
