android - SwipeRefreshLayout 向上滚动时阻碍recycleview的滚动

Question

在我的回收 View 中，当我在列表中向上滚动时，swiperefreshlayout 被触发，这阻碍了我的列表向上移动。我经历了this博客，但它解决了 ListView 的这个问题。对于 recycleview 的这个问题是否有任何类似的解决方法，因为本博客中使用的 onscrollListener 已被弃用。

我终于通过实现 recyclerview 的 setOnScrollListener 实现了正确的行为。

 @Override
        public void onScrolled(RecyclerView recyclerView, int dx, int dy) {
            int topRowVerticalPosition =
                    (recyclerView == null || recyclerView.getChildCount() == 0) ? 0 : recyclerView.getChildAt(0).getTop();
            swipeRefreshLayout.setEnabled(topRowVerticalPosition >= 0);

        }
