Android LoginActivity、Facebook CallbackManager和Graph API请求：executeAndWait（）方法不起作用

我是android新手，我正在构建一个需要登录的应用程序。到目前为止，google+和基本的电子邮件登录都很有效，但我在Facebook登录时遇到了麻烦。我的大部分代码都来自Facebook开发者文档，我曾尝试用不同的方式解决这个问题，但没有成功

这是我的onCreate方法，我在其中设置callbackManager和loginButton。loginButton注册回调。如果成功，它将启动一个图形请求。但是，

executeAndWait（）

方法永远不起作用

 @Override
 public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    FacebookSdk.sdkInitialize(getApplicationContext());
    setContentView(R.layout.activity_login);

    mFacebookCallbackManager = CallbackManager.Factory.create();

    // Set up facebook login button
    LoginButton facebookLoginButton = (LoginButton) findViewById(R.id.facebook_sign_in_button);
    facebookLoginButton.setReadPermissions("public_profile", "email");

    facebookLoginButton.registerCallback(mFacebookCallbackManager, new FacebookCallback<LoginResult>() {
        @Override
        public void onSuccess(LoginResult loginResult) {
            Log.e("callback", "success");
            new GraphRequest(AccessToken.getCurrentAccessToken(), "/me", null, HttpMethod.GET, new GraphRequest.Callback() {
                public void onCompleted(GraphResponse response) {
                    /* handle the result */
                    try {
                        getFacebookUserData(response.getJSONObject());
                    } catch (JSONException e) {
                        Log.e("graph request", "json exception");
                        e.printStackTrace();
                    }
                }
            }
            ).executeAndWait(); //<<<<----- problem is here!!! :(
            Log.e("graph request", "executed");
            uploadUserToServer();
            startLaunchActivity();
        }

        @Override
        public void onCancel() { }

        @Override
        public void onError(FacebookException exception) {
            Log.e("callback", "error");
            exception.printStackTrace();}

    });

}

在我的代码中还有其他一些方法我还没有展示，但是它们做了其他不相关的事情。这段代码还不包括google+登录，这给它的

onConnectedMethod（）

增加了一层难度。我只想执行GraphRequest

这是日志

使用此代码登录facebook。这对我很有用

callbackManager=callbackManager.Factory.create（）；
loginButton=（loginButton）findviewbyd（R.id.login_按钮）；
ListpermissionNeeds=Arrays.asList（“用户照片”、“电子邮件”，
“用户生日”、“公共个人资料”、“AccessToken”）；
loginButton.registerCallback（callbackManager，
新建FacebookCallback（）{@Override
成功时公共无效（LoginResult LoginResult）{
System.out.println（“onSuccess”）；
字符串accessToken=loginResult.getAccessToken（）
.getToken（）；
Log.i（“accessToken”，accessToken）；
GraphRequest请求=GraphRequest.newmereRequest(
loginResult.getAccessToken（），
新建GraphRequest.GraphJSONObjectCallback（）{@Override
未完成的公共void（JSONObject对象，
GraphResponse（反应）{
Log.i（“LoginActivity”，
response.toString（））；
试一试{
stringid=object.getString（“id”）；
试一试{

"http://graph.facebook.com/“+id+”/picture？type=large”）；
Log.i（“个人资料图片”，

}
}
});
Bundle参数=新Bundle（）；
parameters.putString（“字段”，
“身份证、姓名、电子邮件、性别、生日”）；
请求。设置参数（参数）；
request.executeAsync（）；
}
@凌驾
公开作废{
System.out.println（“onCancel”）；
}
@凌驾
public void onError（facebook异常）{
System.out.println（“onError”）；
Log.v（“LoginActivity”，exception.getCause（）.toString（））；
}
});

这就像一个Asynctask任务，这意味着它需要时间，我需要知道这是完成的，并且应该得到值我将如何做？我有同样的问题，下面的答案对我有效，但现在我有一个问题，我应该知道任务何时完成，并且应该得到值，请帮助我
