推荐答案

我发现一个回答我的问题。我手动启用swipeRefreshLayout当第一个孩子在列表视图位于列表的顶部。

I found an answer to my question. I am manually enabling the swipeRefreshLayout when the first child in the listview is at the top of the list.

    listView.setOnScrollListener(new AbsListView.OnScrollListener() {
        @Override
        public void onScrollStateChanged(AbsListView view, int scrollState) {

        }

        @Override
        public void onScroll(AbsListView view, int firstVisibleItem, int visibleItemCount, int totalItemCount) {
            int topRowVerticalPosition = (listView == null || listView.getChildCount() == 0) ?
                            0 : expandableListView.getChildAt(0).getTop();
            refresh.setEnabled((topRowVerticalPosition >= 0));
        }
    });
