URLConnection联网获得数据(解析数组开头的json)



//路径

String dataUrl = "http://121.42.8.95:8090/AndroidServer/NewsManager";

Handler handler = new Handler() {

  public void handleMessage(android.os.Message msg) {

   final Bean[] beans = (Bean[]) msg.obj;

   });

  };
 };

//不要忘记开启线程

new Thread() {

   public void run() {

    try {

     URL url = new URL(dataUrl);

     HttpURLConnection openConnection = (HttpURLConnection) url
       .openConnection();

     openConnection.setRequestMethod("GET");

     openConnection.connect();

     if (openConnection.getResponseCode() == 200) {

      InputStream inputStream = openConnection
        .getInputStream();
      // 解析json
      Gson gson = new Gson();

      Bean[] beans = gson.fromJson(new InputStreamReader(
        inputStream), Bean[].class);

      // 发送给handler
      Message message = Message.obtain();

      message.obj = beans;

      handler.sendMessage(message);

     }
