Class Overview

Wraps a view in a card-styled frame with a white background, rounded corners and a light drop-shadow. This layout is designed to be given a height of WRAP_CONTENT within a container with a fixed height.

To function properly, this view should be contained within a CardScrollView. A CardFragment provides this automatically.

Public Methods

public void addView (View child)

public void addView (View child, int index)

public void addView (View child, int index, ViewGroup.LayoutParams params)

public void addView (View child, ViewGroup.LayoutParams params)

public int getContentPaddingBottom ()

Returns the inner padding before the Card's bottom edge

public int getContentPaddingLeft ()

Returns the inner padding after the Card's left edge

public int getContentPaddingRight ()

Returns the inner padding before the Card's right edge

public int getContentPaddingTop ()

Returns the inner padding after the Card's top edge

public static int getDefaultSize (int size, int measureSpec, boolean greedy)

Get a default size, will be as small as possible unless forced by the parent, or greedy is specified.

public int getExpansionDirection ()

Returns the current expansion direction, either EXPAND_UP or EXPAND_DOWN.

public float getExpansionFactor ()

Returns the current expansionFactor which is the maximum height of this view as a multiple of the parent view's height.

public boolean isExpansionEnabled ()

Indicates whether expansion is on. A CardFrame will increase in height up to expansionFactor times the parent view's height. When expansion is enabled, content which is taller than this will have a fading effect applied to the expanding edge, otherwise content is simply clipped.

public WindowInsets onApplyWindowInsets (WindowInsets insets)

public void onInitializeAccessibilityEvent (AccessibilityEvent event)

public void onInitializeAccessibilityNodeInfo (AccessibilityNodeInfo info)

public void setExpansionDirection (int direction)

Sets the direction in which content expands. Determines whether the top or bottom edge receives the fading edge appearance and whether more content is viewed by scrolling up or down, after increasing the expansion factor.

public void setExpansionEnabled (boolean enabled)

Enables support contents which maybe be larger than the card's container. When expansion is enabled, and the contents are larger than the card, the top or bottom edge will fade to indicate this. The expansion factor must also be increased to allow the card to increase in height.

public void setExpansionFactor (float expansionFactor)

Sets the allowed expansion amount as a multiple of the parent height. If expansion is enabled, the card will grow up to this height as needed to accommodate content.

public boolean shouldDelayChildPressedState ()

Protected Methods

protected boolean drawChild (Canvas canvas, View child, long drawingTime)

protected void onAttachedToWindow ()

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

protected void onMeasure (int widthMeasureSpec, int heightMeasureSpec)
