Android 滑动刷新布局内的可扩展ListView不'；行不通

我正在尝试在可扩展列表视图中应用滑动刷新，当列表视图滚动到底部时，我尝试向上滚动，但它不向上滚动，滑动刷新布局激活，如何解决此问题？任何想法

swipeRefreshLayout.setEnabled(false);
expandableListView.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 = (expandableListView == null || expandableListView.getChildCount() == 0) ? 0 : expandableListView.getChildAt(0).getTop();
        swipeRefreshLayout.setEnabled(firstVisibleItem == 0 && topRowVerticalPosition >= 0);
    }
});
