Question

我想在我的启动画面的文本视图中显示从http://localhost/test/getcontent1.php开始的消息

我写了一个将回显jsno数据的php文件

<?php
$strorg = '[{"code":"101","message":"OK"}]';
$str = json_encode($strorg);
echo $str;
?>

链接的输出是＆＃34; [{\＆＃34;代码\＆＃34;：\＆＃34; 101 \＆＃34; \＆＃34;消息\＆＃34;：\＆＃34; OK \＆＃34;}]＆＃34;

我在splashscreen活动中编写了以下代码

public class SplashScreen extends Activity {

  @Override
  protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_splash);
    final TextView mTxtDisplay;
    mTxtDisplay = (TextView) findViewById(R.id.txtDisplay);
    String url = "http://localhost/test/getcontent1.php";
    mTxtDisplay.setText("Begin");
    JsonObjectRequest jsObjRequest = new JsonObjectRequest
        (Request.Method.GET, url, null, new Response.Listener<JSONObject>() {

          @Override

          public void onResponse(JSONObject response) {
            mTxtDisplay.setText("Response: " + response.toString());
          }
        }, new Response.ErrorListener() {
          @Override
          public void onErrorResponse(VolleyError error) {
            mTxtDisplay.setText(error.toString());
          }
        });


     Thread timerThread = new Thread() {
        public void run() {
          try {
            sleep(3000);
          } catch (InterruptedException e) {
            e.printStackTrace();
          } finally {
            Intent intent = new Intent(SplashScreen.this, MainActivity.class);
            startActivity(intent);
          }
        }
      };
      timerThread.start(); 
  }

  @Override
  protected void onPause() {
    // TODO Auto-generated method stub
    super.onPause();
    finish();
  }
}

但我没有得到任何回应。 textview只显示BEGIN sombody可以有任何解决方案吗？因为我是android的新手

JsonObjectRequest - 不工作，因为它没有收到任何响应
