使用一個xlistview的mod,可自行在網路下載
把mod關聯一下

程式碼:

public class Frag_XListView extends Fragment {
    private XListView xListView;
    private boolean work;
    private List<JsonBean.DataBean> data;
    private String str="http://api.expoon.com/AppNews/getNewsList/type/1/p/1";
    @Nullable
    @Override
    public View onCreateView(@NonNull LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {
        View view = inflater.inflate(R.layout.frag_xlistview, container, false);
        work = HttpUtils.isWork(getActivity());

        xListView = view.findViewById(R.id.frag_xlistview);
        //開啟上拉
        xListView.setPullLoadEnable(true);

        xListView.setXListViewListener(new XListView.IXListViewListener() {
            @Override
            public void onRefresh() {
                //下拉重新整理
                if(work){
                    HttpUtils.httpAsynTask(str, new HttpUtils.CallBackString() {
                        @Override
