Public constructors

FabTransformationSheetBehavior

FabTransformationSheetBehavior ()

FabTransformationSheetBehavior

FabTransformationSheetBehavior (Context context, 
                AttributeSet attrs)

Parameters
context	Context
attrs	AttributeSet

Protected methods

onCreateMotionSpec

FabTransformationBehavior.FabTransformationSpec onCreateMotionSpec (Context context, 
                boolean expanded)

Parameters
context	Context
expanded	boolean

Returns
FabTransformationBehavior.FabTransformationSpec

onExpandedStateChange

boolean onExpandedStateChange (View dependency, 
                View child, 
                boolean expanded, 
                boolean animated)

Reacts to a change in expanded state. This callback is guaranteed to be called only once even if setExpanded(boolean) is called multiple times with the same value. Upon configuration change, this callback is called with animated set to false.

Parameters
dependency	View: the ERROR(/ExpandableWidget) dependency containing the new expanded state.
child	View: the view that should react to the change in expanded state.
expanded	boolean: the new expanded state.
animated	boolean: true if ERROR(/ExpandableWidget#setExpanded(boolean)) was called, false if restoring from a configuration change.

Returns
boolean	true if the Behavior changed the child view's size or position, false otherwise.
