fun onSwiped(viewHolder: ViewHolder, direction: Int): Unit
Called when a ViewHolder is swiped by the user.
If you are returning relative directions ({@link #START} , {@link #END}) from the {@link #getMovementFlags(RecyclerView, ViewHolder)} 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 {@link #clearView(RecyclerView, ViewHolder)}.
viewHolder - The ViewHolder which has been swiped by the user.
direction - The direction to which the ViewHolder is swiped. It is one of
{@link #UP}, {@link #DOWN},
{@link #LEFT} or {@link #RIGHT}. If your
{@link #getMovementFlags(RecyclerView, ViewHolder)}
method
returned relative flags instead of {@link #LEFT} / {@link #RIGHT};
direction will be relative as well. ({@link #START} or {@link
#END}).
