java - 如何使用 facebook sdk 从 facebook 个人资料中获取 id 和姓名？

Question

我知道这种方法是使用 JSON，并且我已经阅读了很多有关如何执行此操作的信息，但我仍然无法弄清楚必须将 JSON 代码放在哪里，以便我可以获得 id 和名称，因为我的一切尝试无效(为空)。你们能给我一个建议，告诉我应该在哪里索取身份证件和姓名，以便我能真正得到它们吗？这是我的主类(class)中与 facebook 相关的所有内容:

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    this.facebookConnector.getFacebook().authorizeCallback(requestCode, resultCode, data);
}

@Override
protected void onResume() {
    super.onResume();
    updateLoginStatus();
}

public void updateLoginStatus() {
    loginStatus.setText("Logged into Facebook as "+        facebookConnector.getUserName() + facebookConnector.getFacebook().isSessionValid());
}

public void postMessage() {

    if (facebookConnector.getFacebook().isSessionValid()) {
        postMessageInThread();
    } else {
        SessionEvents.AuthListener listener = new SessionEvents.AuthListener() {

            @Override
            public void onAuthSucceed() {
                postMessageInThread();
            }

            @Override
            public void onAuthFail(String error) {

            }
        };
        SessionEvents.addAuthListener(listener);
        facebookConnector.login();

    }
}

private void postMessageInThread() {
    Thread t = new Thread() {
        public void run() {

            try {
                facebookConnector.postMessageOnWall("test");
                mFacebookHandler.post(mUpdateFacebookNotification);
            } catch (Exception ex) {
                Log.e(TAG, "Error sending msg",ex);
            }
        }
    };
    t.start();
}

private void clearCredentials() {
    try {
        facebookConnector.getFacebook().logout(getApplicationContext());
    } catch (MalformedURLException e) {
        e.printStackTrace();
    } catch (IOException e) {
        e.printStackTrace();
    }
}

我上次尝试过

 AsyncFacebookRunner myAsyncRunner = new AsyncFacebookRunner(facebook);
    myAsyncRunner.request("me", new meRequestListener());

然后

 public class meRequestListener implements RequestListener {

    public void onComplete(String response, Object state) {

        fbName = response;
    }

当我得到字符串时

public String getUserName () {
    return fbName;
}

它仍然是空的。请帮忙。

你可以使用这个:(此代码使用 Facebook SDK 3.02)

用户 ID:

final Session session = Session.getActiveSession();
    if (session != null && session.isOpened()) {
        // If the session is open, make an API call to get user data
        // and define a new callback to handle the response
        Request request = Request.newMeRequest(session, new Request.GraphUserCallback() {
            @Override
            public void onCompleted(GraphUser user, Response response) {
                // If the response is successful
                if (session == Session.getActiveSession()) {
                    if (user != null) {
                        user_ID = user.getId();//user id
                        profileName = user.getName();//user's profile name
                        userNameView.setText(user.getName());
                    }   
                }   
            }   
        }); 
        Request.executeBatchAsync(request);
    }  

user_ID 和 profileName 是字符串。
