Android 无法从GraphRequest Facebook获取值

我正在使用Facebook SDK 4.16.1通过使用

Profile

我可以得到

名字

，

姓氏

，

名字

和

id

我的代码是这样的

public class LoginActivity extends Activity {

String id, fname, lname, email, name, gender, locale, verified;
private CallbackManager callbackManager;
private AccessTokenTracker accessTokenTracker;

 @Override
protected void onCreate(Bundle savedInstanceState) {
 super.onCreate(savedInstanceState);
 setContentView(R.layout.loginactivity);

FacebookSdk.sdkInitialize(getApplicationContext());
    callbackManager = CallbackManager.Factory.create();

    accessTokenTracker = new AccessTokenTracker() {
        @Override
        protected void onCurrentAccessTokenChanged(AccessToken oldToken, AccessToken newToken) {
        }
    };

    LoginButton loginButton = (LoginButton)findViewById(R.id.login_button);
    loginButton.setReadPermissions(Arrays.asList(Constants.FACEBOOK_PERMISSIONS));

    FacebookCallback<LoginResult> callback = new FacebookCallback<LoginResult>() {
        @Override
        public void onSuccess(LoginResult loginResult) {
            AccessToken accessToken = loginResult.getAccessToken();
            Profile profile = Profile.getCurrentProfile();

            FB_TOKEN=loginResult.getAccessToken().getToken();

            GraphRequest request = GraphRequest.newMeRequest(
                    loginResult.getAccessToken(),
                    new GraphRequest.GraphJSONObjectCallback() {
                        @Override
                        public void onCompleted(
                                JSONObject object,
                                GraphResponse response) {
                            // Application code
                            response.getError();
                            Log.e("JSON:", object.toString());

                            try {
                                email = object.getString("email");

                            } catch (JSONException e) {
                                e.printStackTrace();
                            }
                        }
                    });
            Bundle parameters = new Bundle();
            parameters.putString("fields", "id,name,link,birthday,first_name,last_name,email,gender,verified,locale");
            request.setParameters(parameters);
            request.executeAsync();


            id = profile.getId();
            fname = profile.getFirstName();
            lname = profile.getLastName();
            name = profile.getName();

            nextActivity(profile);
            Toast.makeText(getApplicationContext(), "Logging in...", Toast.LENGTH_SHORT).show();
        }

        @Override
        public void onCancel() {
        }

        @Override
        public void onError(FacebookException e) {
        }
    };

    loginButton.registerCallback(callbackManager, callback);
}

 }

public static final String[] FACEBOOK_PERMISSIONS = new String[] {
                                                                "public_profile",
                                                                "user_friends",
                                                                "email" };

GraphRequest request = GraphRequest.newMeRequest(
                    loginResult.getAccessToken(),
                    new GraphRequest.GraphJSONObjectCallback() {

                                GraphResponse response) {

                            response.getError();
                            Log.e("JSON-RESULT:", object.toString());

                            JSONObject jsonObject = null;
                            try {

                                email = jsonObject.getString("email");
                                gender = jsonObject.getString("gender");
                                locale = jsonObject.getString("locale");
                                verified = jsonObject.getString("verified");

                                Log.e(TAG, email + " This is the email");
                            } catch (JSONException e) {

                            }
                        }
                    });
            Bundle parameters = new Bundle();
            parameters.putString("fields", "id,name,link,birthday,first_name,last_name,email,gender,verified,locale");
            request.setParameters(parameters);
            request.executeAsync();

我正在尝试获取电子邮件、性别、地区以及是否已经验证。我将如何获得其他信息？除了通过

Profile

更新

我像这样更新我的

在我的

Logcat

中，它显示我正确设置了电子邮件和其他邮件，但当你设置

断点时，它没有进入
GraphRequest
，因此我的全局
变量
电子邮件仍然为空。即使在
Log.e（“JSON:，object.toString（））和
Log.e（标签，电子邮件+“这就是电子邮件”）它显示我获取并设置值。我想知道如何获取
Bundle
的值？
尝试使用下面的代码获取其他信息

 private FacebookCallback<LoginResult> mFacebookCallback = new FacebookCallback<LoginResult>() {
            @Override
            public void onSuccess(LoginResult loginResult) {
               // Log.d("Login", "onSuccess");
                GraphRequest.newMeRequest(
                        loginResult.getAccessToken(), new GraphRequest.GraphJSONObjectCallback() {
                            @Override
                            public void onCompleted(JSONObject me, GraphResponse response) {
                                if (response.getError() != null) {
                                    // handle error
                                } else {
                                    email = me.optString("email");
                                    String id = me.optString("id");
                                    String email=me.optString("email");
                                    String name= me.optString("name");
                                    String gender= me.optString("gender");
                                    String verified= me.optBoolean("is_verified") + "";

你看到了吗？所以我将在fb sdk 4.1中的
onCreate
中调用
mFacebookCallback
？如果你检查了官方文档，请注册回拨并在onCreateView中调用我看到了，我错过了这一部分，我应该把它全部放在一个片段中，我现在就编辑它，因为我把它都放在了我的活动中。没有问题，你可以尝试一下，如果需要任何帮助，你可以问我。。如果它帮助你，那么请接受并投票，这样别人也可以认为这是正确答案。
