@ u013280307 谢谢您的回复
还想请问下：
在fragment里边： 当下拉更新的时候，会调用onRefresh() 函数：
当下拉更新的时候，比如说 设置的时间是5000， 但是当那个下拉更新的图标提示消失了，而 那个mChat.updatedata（）里边数据还没有解析完，但是它是回调了这个onDone（）函数了。
。。。。
mListView.setXListViewListener(new IXListViewListener(){
public void onRefresh() {
mmHandler.postDelayed(new Runnable() {
@Override
public void run() {
mChat.updatedata(null,new ChatCallBack(){
public void onDone(ListMemberInfo> list){
listdata.clear();
listdata= list;
Message mes = mHandler.obtainMessage(2);
mHandler.sendMessage(mes);
}
});
mListView.stopRefresh();
mListView.stopLoadMore();
}
}, 5000);
}
private final Handler mHandler = new Handler() {
public void handleMessage(Message msg) {
switch (msg.what) {
case 1:
mGetAdapter = ChatGetAdapter(getActivity(),listdata);
mListView.setAdapter(mGetAdapter);
break;
case 2:
mGetAdapter.update(listdata);
break;
default:
break;
}
super.handleMessage(msg);
}
};
—————————————
在
public class GetAdapte extends BaseAdapter {
。。。。
public GetAdapte( Context context,List<MemberInfo>list ) {
super();
this.context = context;
layoutInflater = (LayoutInflater)context.getSystemService(inflater);
this.mberlist = list;
}
public void setmList( List<MemberInfo> mList) {
this.Memberlist = mList;
}
public void update(List<Info> list) {
setmList(list);
this.notifyDataSetChanged();
}
public View getView(int position,View convertView,ViewGroup parent ) {
。。。。。。。。。。。
}
}
还有一个问题是：上面的代码会出现以下错误提示：
请问 它是通过 sendmessage（）然后在mGetAdapter.update(listdata); 这个应该怎么处理呢？
