android - Facebook Android SDK 4.0.0 未获取个人资料信息

在我的应用程序中登录到 Profile.getCurrentProfile() 后，我遇到了获取 Facebook 的问题。我正在使用 Facebook Android SDK 4.0.0 。登录后，我想获取用户名并将其显示在 TextView 中，但我得到的是 profile == null，我不知道为什么。我有正确的应用程序 ID 和 HashKey 。

这是我的代码:

public class MyFragment extends Fragment {

    CallbackManager callbackManager;
    LoginButton loginButton;
    FacebookCallback<LoginResult> loginResultFacebookCallback = new FacebookCallback<LoginResult>() {
        @Override
        public void onSuccess(LoginResult loginResult) {
            AccessToken accessToken = loginResult.getAccessToken();
            Log.e("FB", String.valueOf(accessToken));
            Profile profile = Profile.getCurrentProfile();

            if (profile != null) {
                name.setText("Witam " + profile.getName());
                Log.e("FB", "w");
            }
        }

        @Override
        public void onCancel() {
            // App code
        }

        @Override
        public void onError(FacebookException exception) {
            // App code
        }
    };
    TextView name;

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        FacebookSdk.sdkInitialize(getActivity().getApplicationContext());
        callbackManager = CallbackManager.Factory.create();
    }

    @Override
    public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {
        View view = inflater.inflate(R.layout.myfragment_facebook, container, false);
        name = (TextView) view.findViewById(R.id.name);
        return view;
    }

    @Override
    public void onViewCreated(View view, @Nullable Bundle savedInstanceState) {
        super.onViewCreated(view, savedInstanceState);
        loginButton = (LoginButton) view.findViewById(R.id.login_button);
        loginButton.setReadPermissions(Arrays.asList("public_profile", "user_friends"));
        loginButton.setFragment(this);
        loginButton.registerCallback(callbackManager, loginResultFacebookCallback);
    }

    @Override
    public void onActivityResult(int requestCode, int resultCode, Intent data) {
        super.onActivityResult(requestCode, resultCode, data);
        callbackManager.onActivityResult(requestCode, resultCode, data);
    }
}

当我在 Logcat 中检查 Token 时，我得到 AccessToken token:ACCESS_TOKEN_REMOVED

最佳答案

登录发生后异步获取配置文件。如果要跟踪它，类似于此示例:https://github.com/facebook/facebook-android-sdk/blob/b384c0655fe96db71229bfdcb981a522f3f1e675/samples/SwitchUserSample/src/com/facebook/samples/switchuser/ProfileFragment.java#L54
