onSwiped
Called when a ViewHolder is swiped by the user.
If you are returning relative directions (START , END) from the getMovementFlags method, this method will also use relative directions. Otherwise, it will use absolute directions.
If you don't support swiping, this method will never be called.
ItemTouchHelper will keep a reference to the View until it is detached from RecyclerView. As soon as it is detached, ItemTouchHelper will call clearView.
