Create a drawable by opening a given file path and decoding the bitmap.

Create a drawable by decoding a bitmap from the given input stream.

Create a drawable by decoding a bitmap from the given input stream.

Applies the specified theme to this Drawable and its children.

Draw in its bounds (set via setBounds) respecting optional effects such as alpha (set via setAlpha) and color filter (set via setColorFilter).

Gets the current alpha value for the drawable. 0 means fully transparent, 255 means fully opaque. This method is implemented by Drawable subclasses and the value returned is specific to how that class treats alpha. The default return value is 255 if the class does not override this method to return a value specific to its use of alpha.

Returns the bitmap used by this drawable to render. May be null.

Return a mask of the configuration parameters for which this drawable may change, requiring that it be re-created. The default implementation returns whatever was provided through setChangingConfigurations(int) or 0 by default. Subclasses may extend this to or in the changing configurations of any other drawables they hold.

Returns the current color filter, or null if none set.

Return a Drawable.ConstantState instance that holds the shared state of this Drawable.

Get the gravity used to position/stretch the bitmap within its bounds. See android.view.Gravity

Return the intrinsic height of the underlying drawable object. Returns -1 if it has no intrinsic height, such as with a solid color.

Return the intrinsic width of the underlying drawable object. Returns -1 if it has no intrinsic width, such as with a solid color.

Return the opacity/transparency of this Drawable. The returned value is one of the abstract format constants in PixelFormat: UNKNOWN, TRANSLUCENT, TRANSPARENT, or OPAQUE.

An OPAQUE drawable is one that draws all all content within its bounds, completely covering anything behind the drawable. A TRANSPARENT drawable is one that draws nothing within its bounds, allowing everything behind it to show through. A TRANSLUCENT drawable is a drawable in any other state, where the drawable will draw some, but not all, of the content within its bounds and at least some content behind the drawable will be visible. If the visibility of the drawable's contents cannot be determined, the safest/best return value is TRANSLUCENT.

Generally a Drawable should be as conservative as possible with the value it returns. For example, if it contains multiple child drawables and only shows one of them at a time, if only one of the children is TRANSLUCENT and the others are OPAQUE then TRANSLUCENT should be returned. You can use the method resolveOpacity(int, int) to perform a standard reduction of two opacities to the appropriate single output.

Note that the returned value does not necessarily take into account a custom alpha or color filter that has been applied by the client through the setAlpha(int) or setColorFilter(ColorFilter) methods. Some subclasses, such as BitmapDrawable, ColorDrawable, and GradientDrawable, do account for the value of setAlpha(int), but the general behavior is dependent upon the implementation of the subclass.

Called to get the drawable to populate the Outline that defines its drawing area.

This method is called by the default ViewOutlineProvider to define the outline of the View.

The default behavior defines the outline to be the bounding rectangle of 0 alpha. Subclasses that wish to convey a different shape or alpha value must override this method.

Returns the paint used to render this drawable.

Indicates the repeat behavior of this drawable on the X axis.

Indicates the repeat behavior of this drawable on the Y axis.

Indicates whether anti-aliasing is enabled for this drawable.

Indicates whether the mipmap hint is enabled on this drawable's bitmap.

Inflate this Drawable from an XML resource optionally styled by a theme.

Tells if this Drawable will be automatically mirrored when its layout direction is RTL right-to-left. See LayoutDirection.

Indicates whether this drawable will change its appearance based on state. Clients can use this to determine whether it is necessary to calculate their state and call setState.

A mutable BitmapDrawable still shares its Bitmap with any other Drawable that comes from the same resource.

Specify an alpha value for the drawable. 0 means fully transparent, and 255 means fully opaque.

Enables or disables anti-aliasing for this drawable. Anti-aliasing affects the edges of the bitmap only so it applies only when the drawable is rotated.

Set whether this Drawable is automatically mirrored when its layout direction is RTL (right-to left). See LayoutDirection.

Specify an optional color filter for the drawable.

If a Drawable has a ColorFilter, each output pixel of the Drawable's drawing contents will be modified by the color filter before it is blended onto the render target of a Canvas.

Pass null to remove any existing color filter.

Note: Setting a non-null color filter disables tint.

Set to true to have the drawable dither its colors when drawn to a device with fewer than 8-bits per color component.

Set to true to have the drawable filter its bitmaps with bilinear sampling when they are scaled or rotated.

This can improve appearance when bitmaps are rotated. If the drawable does not use bitmaps, this call is ignored.

Set the gravity used to position/stretch the bitmap within its bounds. See android.view.Gravity

Enables or disables the mipmap hint for this drawable's bitmap. See setHasMipMap(boolean) for more information. If the bitmap is null calling this method has no effect.

Set the density at which this drawable will be rendered.

Set the density scale at which this drawable will be rendered.

Set the density scale at which this drawable will be rendered. This method assumes the drawable will be rendered at the same density as the specified canvas.

Sets the repeat behavior of this drawable on the X axis. By default, the drawable does not repeat its bitmap. Using REPEAT or MIRROR the bitmap can be repeated (or tiled) if the bitmap is smaller than this drawable.

Sets the repeat behavior of this drawable on both axis. By default, the drawable does not repeat its bitmap. Using REPEAT or MIRROR the bitmap can be repeated (or tiled) if the bitmap is smaller than this drawable.

Sets the repeat behavior of this drawable on the Y axis. By default, the drawable does not repeat its bitmap. Using REPEAT or MIRROR the bitmap can be repeated (or tiled) if the bitmap is smaller than this drawable.

Specifies tint color for this drawable as a color state list.

A Drawable's drawing content will be blended together with its tint before it is drawn to the screen. This functions similarly to setColorFilter(int, PorterDuff.Mode).

Note: Setting a color filter via setColorFilter(ColorFilter) or setColorFilter(int, PorterDuff.Mode) overrides tint.

Specifies a tint blending mode for this drawable.

Defines how this drawable's tint color should be blended into the drawable before it is drawn to screen. Default tint mode is SRC_IN.

Note: Setting a color filter via setColorFilter(ColorFilter) or setColorFilter(int, PorterDuff.Mode) overrides tint.

Override this in your subclass to change appearance if you vary based on the bounds.

Override this in your subclass to change appearance if you recognize the specified state.
