abstract class SimpleCallback : ItemTouchHelper.Callback
   ↳ androidx.recyclerview.widget.ItemTouchHelper.Callback
   ↳ androidx.recyclerview.widget.ItemTouchHelper.SimpleCallback

A simple wrapper to the default Callback which you can construct with drag and swipe directions and this class will handle the flag callbacks. You should still override onMove or onSwiped depending on your use case.

ItemTouchHelper mIth = new ItemTouchHelper(
          new ItemTouchHelper.SimpleCallback(ItemTouchHelper.UP | ItemTouchHelper.DOWN,
              ItemTouchHelper.LEFT) {
              public boolean onMove(RecyclerView recyclerView,
                  ViewHolder viewHolder, ViewHolder target) {
                  final int fromPos = viewHolder.getAdapterPosition();
                  final int toPos = target.getAdapterPosition();
                  // move item in `fromPos` to `toPos` in adapter.
                  return true;// true if moved, false otherwise
              public void onSwiped(ViewHolder viewHolder, int direction) {
                  // remove from adapter
