在我的RecycleView中,当我在列表中向上滚动时,会触发SwipereFreshLayout,从而阻止列表向上移动。我浏览了this博客,但它为listview解决了这个问题。对于RecycleView,是否有类似的解决方法,因为OnScrollListener已被弃用,它已在本博客中使用。

最佳答案
我最终实现了recycleview的setonscrollllistener,从而实现了正确的行为。
@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);
}
关于android - SwipeRefreshLayout在向上滚动时阻碍了recycleview的滚动,我们在Stack Overflow上找到一个类似的问题:https://stackoverflow.com/questions/33931928/
