onCompleted無法正常工作？

Question

這似乎沒有連接和更新Facebook API的文本字段，任何人都可以看到問題。我不得不將Request.executeMeRequestAsyc更改爲Request.newMeRequest，因爲它已被棄用。任何幫助，將不勝感激。

代碼片斷

你需要調用executeAsync上明確要求：

 if (session.isOpened()) { 
      //---make request to the /me api--- 
      Request.newMeRequest(session, new Request.GraphUserCallback() { 

       @Override 
       public void onCompleted(GraphUser user, Response response) { 
        // TODO Auto-generated method stub 
        if(user != null){ 
         TextView welcome = (TextView) findViewById(R.id.welcome); 
         welcome.setText("Hello " + user.getName() + "!"); 
        } 

       } 
      }).executeAsync(); // <----- ADD THIS 
     }
