Answer 1

@Overid
private void onDrop(int from, int to) {   // this listener only calls when item Droped after drag
    ExerciseDetails moveItem = items.remove(from);
    items.add(moveItem, to)
    int minPosition = from > to ? to : from;
    int maxPosition = from > to ? from : to;
    // now the item index is the sort index of ExerciseDetails
    for (int i = minPosition; i <= maxPosition; i++) {
        ExerciseDetails item = items.get(i);
        item.setOrder(i);
        exercisesDAO.updateOrder(i, item.getExDetailsId());
    }
    // notify recyclerview to refresh the position of item dragged
    adapter.notifyItemMoved(from, to)
}
