Java SwipeHelper onTouchListener未更新位置

我正在尝试在一个RecyclerView项下制作一个可滑动按钮，如下所示：

我通过使用swipeheloper.class来实现这一点。但是，第一次使用时代码运行良好。但是，当我删除第二项时，即如果有3项，我删除no3，然后尝试删除no2。我收到一个

null对象引用错误

  private View.OnTouchListener onTouchListener = new View.OnTouchListener() {
        @Override
        public boolean onTouch(View view, MotionEvent e) {
            if (swipedPos < 0) return false;
            Point point = new Point((int) e.getRawX(), (int) e.getRawY());
            Log.d("message", "hey" + swipedPos);
//HERE IS THE CODE THAT TRIGGERS THE ERROR _______
                RecyclerView.ViewHolder swipedViewHolder = recyclerView.findViewHolderForAdapterPosition(swipedPos);
//ERROR ABOVE _______
            assert swipedViewHolder != null;
            View swipedItem = swipedViewHolder.itemView;
            Rect rect = new Rect();
            swipedItem.getGlobalVisibleRect(rect);

            if (e.getAction() == MotionEvent.ACTION_DOWN || e.getAction() == MotionEvent.ACTION_UP ||e.getAction() == MotionEvent.ACTION_MOVE) {
                if (rect.top < point.y && rect.bottom > point.y)
                    gestureDetector.onTouchEvent(e);
                else {
                    recoverQueue.add(swipedPos);
                    swipedPos = -1;
                    recoverSwipedItem();
                }
            }
            return false;
        }
    };

我得到的确切线索是：

 java.lang.NullPointerException: Attempt to read from field 'android.view.View androidx.recyclerview.widget.RecyclerView$ViewHolder.itemView' on a null object reference
        at rg.com.timesaver.ui.history.SwipeHelper$2.onTouch(SwipeHelper.java:56)

有人能解释为什么会发生这种情况并提供解决方案吗
