Parameters
context	Context
attrs	AttributeSet

Public methods

layoutDependsOn

boolean layoutDependsOn (CoordinatorLayout parent, 
                View child, 
                View dependency)

Parameters
parent	CoordinatorLayout
child	View
dependency	View

Returns

Protected methods

onCreateExpandedStateChangeAnimation

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 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.
isAnimating	boolean: whether this state change occurred while a previous state change was still

Returns
AnimatorSet
