`View child`	the view that should react to the change in expanded state.
`boolean expanded`	the new expanded state.
`boolean animated`	true if `setExpanded` 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.
