Question

在我的循环视图中，当我在列表中向上滚动时，触发了swiperefreshlayout，这阻碍了我的列表向上移动。我浏览了this博客，但它解决了listview的这个问题。对于recycleview这个问题是否有任何类似的工作，因为不推荐使用onscrollListener，这在本博客中使用。

Answer 1

我终于通过实现recycleview的setOnScrollListenner来实现正确的行为。

 @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);

        }

Answer 2

这是同样的想法。

您可以自定义RecycleView并设置何时使用触摸事件或传递。

然后SwipeRefreshLayout可以接收触摸事件。

Answer 3

尝试

我无法实现@Manish Patiyal回答的setOnScrollListenner，所以我尝试了另一种对我来说很好的解决方案。

 recycler_view.addOnScrollListener(new RecyclerView.OnScrollListener() { //Used to restrict collapsing of recycler view horizontal swipe and swipe refresh layout
        @Override
        public void onScrolled(RecyclerView recyclerView, int dx, int dy) {
            if (linearlayoutmanager.findFirstCompletelyVisibleItemPosition() == 0)
                swipeRefreshLayout.setEnabled(true);
            else
                swipeRefreshLayout.setEnabled(false);
        }
    });

在向上滚动时，SwipeRefreshLayout会阻碍recycleview的滚动
