准确确定recyclerview项目的当前位置

Question

我想在滚动时计算回收者视图项目的确切位置，我尝试过，但不知道为什么它没有得到我的确切位置。请看一下代码。

recyclerView.addOnScrollListener(new RecyclerView.OnScrollListener() {
        @Override
        public void onScrollStateChanged(RecyclerView recyclerView, int newState) {
            super.onScrollStateChanged(recyclerView, newState);

            if (newState==RecyclerView.SCROLL_STATE_SETTLING){

                int pos = layoutManager.findLastVisibleItemPosition();


                if (pos>=5){
                    v2.setVisibility(View.GONE);  // want to hide view when position 5 has just ended while scrolling upwards

                }else {
                    v2.setVisibility(View.VISIBLE);//// want to show view when position 5 has just ended while scrolling downwards
                }

            }
        }
    });
