和后台交互

需要交互的页面

  sp = getSharedPreferences("HJSmartRouter", MODE_PRIVATE);  userId = sp.getString("userId", null);  token = sp.getString("token", null);  System.out.println("=========="+userId);

  //获取个人资料  GetPersonalInfoRequest getPersonalInfoRequest = new GetPersonalInfoRequest();  getPersonalInfoRequest.setUserId(userId);  getPersonalInfoRequest.setToken(token);  //事件名称，回调事件，要发送的包  new Thread(new HJHttpUrlConnectionUtil("getPersonalInfo", PersonalInfoHandler, getPersonalInfoRequest)).start();

回调

 public Handler PersonalInfoHandler = new Handler() {  public void handleMessage(Message msg) {   byte[] responseJson = msg.getData().getByteArray("responseJson");   try {    getPersonalInfoResponse = mMapper.readValue(responseJson,      new TypeReference<GetPersonalInfoResponse>() {         });   } catch (Exception e) {    e.printStackTrace();   }   mText_name.setText(getPersonalInfoResponse.getBody().getNickName());   mText_gender.setText(getPersonalInfoResponse.getBody().getSex());   mText_email.setText(getPersonalInfoResponse.getBody().getMailAddress());   List<String> strings = getPersonalInfoResponse.getBody().getPersonalityLabel();   mList = strings;//   String [] str = strings.get(0).split(";");//   for (int i = 0; i < str.length; i++) {//    //    //   }   Toast.makeText(HJMyselfDataActivity.this,     getPersonalInfoResponse.getErrorCode(), Toast.LENGTH_LONG)     .show();  } };
