从recycleVIew中删除项目的动画

Question

I have the RecyclerView , ItemTouchHelper and ItemTouchHelper.Callback instances to work together, and on swipe to left the selected item supposed to be removed ( by this tutorial ). The removal animation works, but only partly. First after swipe the item seems to be removed, but after that it reappers, and the list stays still the same:

Why can it happen?

Answer 1

Ensure these two statements

 cartList.remove(position);
        // notify the item removed by position
        // to perform recycler view delete animations
        // NOTE: don't call notifyDataSetChanged()
        notifyItemRemoved(position);

are executing.
