注意:应该在handleMessage中处理从服务器返回的数据。否则会因为线程问题拿不到结果。
public class MainActivity extends Activity{ private String responseInfo; private Handler handler; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); handler = new Handler() { @Override public void handleMessage(Message msg) { super.handleMessage(msg); responseInfo = (String) msg.obj; Gson gson = new Gson(); Type type = new TypeToken<JsonBean>() { }.getType(); JsonBean jsonBean = gson.fromJson(responseInfo, type); System.out.println(jsonBean); } }; getFromServer(); } /** * 使用xutils发送POST请求得到服务器返回的数据 */ public void getFromServer() { String url = "http://182.92.195.162:8088/index.php?r=api/client/init"; RequestParams params = new RequestParams(); JSONObject json = new JSONObject(); JSONObject request = new JSONObject(); try { json.put("uid", ""); json.put("sid", ""); json.put("ver", "1"); json.put("request", request); params.addBodyParameter("json", json.toString()); } catch (Exception e) { e.printStackTrace(); } HttpUtils http = new HttpUtils(); http.send(HttpMethod.POST, url, params, new RequestCallBack<String>() { @Override public void onFailure(HttpException arg0, String arg1) { } @Override public void onSuccess(ResponseInfo<String> arg0) { Message msg = Message.obtain(); msg.obj = arg0.result; handler.sendMessage(msg); } }); } }
