public FabTransformationBehavior (Context context, 
                AttributeSet attrs)

Parameters
context	Context
attrs	AttributeSet

Public methods

Protected methods

onCreateExpandedStateChangeAnimation

protected AnimatorSet onCreateExpandedStateChangeAnimation (View dependency, 
                View child, 
                boolean expanded, 
                boolean isAnimating)

Creates an AnimatorSet to be played for this expanded state change.

If the new expanded state is true, the dependency should be hidden and the child should be shown.

If the new expanded state is false, the dependency should be shown and the child should be hidden.

Parameters
dependency	View: the 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.
isAnimating	boolean: whether this state change occurred while a previous state change was still

Returns
AnimatorSet

onCreateMotionSpec

protected abstract FabTransformationBehavior.FabTransformationSpec onCreateMotionSpec (Context context, 
                boolean expanded)

Parameters
context	Context
expanded	boolean

Returns
FabTransformationBehavior.FabTransformationSpec
