Public Constructors

public CardScrollView (Context context)

public CardScrollView (Context context, AttributeSet attrs)

Public Methods

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

public boolean canScrollHorizontally (int direction)

public int getAvailableScrollDelta (int direction)

Indicates how far the container may be vertically scrolled in the given direction.

When providing a positive direction value, the return value indicates the available increase in scroll position (how far the content can move up). When providing a negative direction value, the return value indicates the available decrease in scroll position (how far the content can move down).

Parameters
direction the direction value to check, only the sign of the value is significant

public int getCardGravity ()

Returns the current layout gravity for contained card frame.

See Also

public int getExpansionDirection ()

Returns the current expansion direction for the contained CardFrame.

See Also

public float getExpansionFactor ()

Returns the current expansion factor for the contained CardFrame.

See Also

public boolean isExpansionEnabled ()

Indicates if expansion is enabled.

public WindowInsets onApplyWindowInsets (WindowInsets insets)

public void setCardGravity (int gravity)

Applies gravity to adjust the vertical alignment of the contained card frame when it's shorter than the containing view.

Supported gravity values are either TOP or BOTTOM.

public void setExpansionDirection (int direction)

Control which direction expansion occurs. When content is taller than this container, this edge will fade to indicate expansion is possible. If expansion is disabled, this edge will simply be clipped. If the card is smaller than this layout, this setting has no effect.

Parameters
direction the direction for content expansion

public void setExpansionEnabled (boolean enableExpansion)

Whether the height of the card is permitted to increase beyond the card layout bounds. If enabled, content will expand the card up to the current expansion level. If taller, a fading edge will indicate that more expansion is possible.

Parameters
enableExpansion whether content will be allowed to expand
See Also

public void setExpansionFactor (float expansionFactor)

Changes the expansion factor for the contained CardFrame.
