ListView只显示第一个子项的情况下，需要设置它的布局参数，以显示全部子项。只需要调用以下函数即可。

private   void setListViewHeightBasedOnChildren(ListView listView) {
   ListAdapter listAdapter = listView.getAdapter();
   if (listAdapter == null) {
    return;
   }
   int totalHeight = 0;
   for (int i = 0, len = listAdapter.getCount(); i < len; i++) {
    View listItem = listAdapter.getView(i, null, listView);
    listItem.measure(0,0);
    totalHeight += listItem.getMeasuredHeight();
   }
    ViewGroup.LayoutParams params = listView.getLayoutParams();
    params.height = totalHeight + (listView.getDividerHeight() * (listAdapter.getCount() - 1));
    listView.setLayoutParams(params);
   }
private void setArrowHind(){
  arrow.setVisibility(View.GONE);
}
