public FabTransformationBehavior (Context context, 
                AttributeSet attrs)

Parameters
`context`	`Context`
`attrs`	`AttributeSet`

Public methods

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

Parameters
`parent`	`CoordinatorLayout`

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`
