ItemTouchUIUtil

android.support.v7.widget.helper.ItemTouchUIUtil

Class Overview

Utility class for ItemTouchHelper which handles item transformations for different API versions.

This class has methods that map to ItemTouchHelper.Callback's drawing methods. Default implementations in ItemTouchHelper.Callback call these methods with itemView and ItemTouchUIUtil makes necessary changes on the View depending on the API level. You can access the instance of ItemTouchUIUtil via getDefaultUIUtil() and call its methods with the children of ViewHolder that you want to apply default effects.
