本文介绍了一个使用AsyncTask进行网络数据加载的例子，并展示了如何解析JSON数据到自定义对象中，最后更新UI显示。

public interface JieKou {
    public void jie(String json);
}

ImageLoaderUtil.init(this);

public static void getDate(Context context, final String path, final JieKou jie){
    if(NeteState.isConn(context)){
        AsyncTask<Void,Void,String> as=new AsyncTask<Void, Void, String>() {
            @Override
            protected String doInBackground(Void... voids) {
                URL url= null;
                try {
                    url = new URL(path);
                    HttpURLConnection connection = (HttpURLConnection) url.openConnection();
                    connection.setRequestMethod("GET");
                    connection.setReadTimeout(5000);
                    connection.setConnectTimeout(5000);
                    int responseCode = connection.getResponseCode();
                    if (responseCode ==200){
                        InputStream inputStream = connection.getInputStream();
                        String json = Strings.streamToString(inputStream, "utf-8");
                         return json;
                    }
                } catch (Exception e) {
                    e.printStackTrace();
                }
                return null;
            }

            @Override
            protected void onPostExecute(String s) {
                super.onPostExecute(s);
                jie.jie(s);
            }
        };
        as.execute();
    }else{
          NeteState.showNoNetWorkDlg(context);
    }
}

然后局可以直接使用了。
NetDate.getDate(getActivity(), "https://api.tianapi.com/wxnew/?key=8d6e3228d25298f13af4fc40ce6c9679&num=10&page=1", new JieKou() {
    @Override
    public void jie(String json) {
        Gson gson=new Gson();
        DataDataBean dataDataBean= gson.fromJson(json, DataDataBean.class);
        List<DataDataBean.NewslistBean> newslist= dataDataBean.getNewslist();
        list.addAll(newslist);
        setadpter();
        //停止刷新
        lv.onRefreshComplete();
    }
});
