ItemTouchHelper - The drop is forced after the first jumped line

Replacing notifyDataSetChanged() by notifyItemMoved() in onMove() method fixed my problem.

Which supprised me as I thought that onMove() was called after the drop. In fact, it has an effect on the drop itself.

For those having the snaping problem when you move an element, if you are using this override

   @Override
    public int getItemViewType(int position) {
        return position;
    }

Just delete it from your adapter and it will work just fine
