我正在使用PullToRefresh来刷新Child Fragment（嵌套片段）中的ListView但是当我将其拉下来时，会出现一些加载动画，但它不会进行任何更改名单。它仅显示以前加载的数据。
这是我的代码： -

请让我知道我在这里缺少的东西。
答案 0 :(得分：0)
谢谢大家的支持。我已经解决了我的问题。
我刚刚在调用refresh（）方法之后添加新项目之前添加了清除listview。
llList.setOnRefreshListener(new OnRefreshListener() {
@Override
public void onRefresh() {
//llList.setAdapter(null);
android.support.v4.app.Fragment fragment = null;
fragment = new OzoneFragment();
APIAccess.fetchData(OzoneFeedFragment.this, getActivity(), getActivity());
llList.postDelayed(new Runnable() {
@Override
public void run() {
llList.onRefreshComplete();
//messageList = new ArrayList<MessageBean>();
UrlIndex=0;
arrList.clear(); //this is what I did torefresh the list
adpter.notifyDataSetChanged();
Log.e("check", "check");
}
}, 2000);
}
});
