登录 Facebook 注册回调未调用

这是我的 onCreate 方法：

@Override
protected void onCreate(Bundle bundle) {
    super.onCreate(bundle);
    setContentView(R.layout.activity_social_login);
    init();
    hideActiveSocialNetworks();
    FacebookSdk.sdkInitialize(getApplicationContext());
    CallbackManager callbackManager = CallbackManager.Factory.create();
    LoginManager.getInstance().registerCallback(callbackManager, new FacebookCallback<LoginResult>() {
        @Override
        public void onSuccess(LoginResult loginResult) {
            // not called
            Log.d("fb_login_sdk", "callback success");
        }

        @Override
        public void onCancel() {
            // not called
            Log.d("fb_login_sdk", "callback cancel");
        }

        @Override
        public void onError(FacebookException e) {
            // not called
            Log.d("fb_login_sdk", "callback onError");
        }
    });

    final Activity activity = this;

    findViewById(R.id.fb_login_sdk).setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            Log.d("fb_login_sdk", "click");
            List<String> perm = new ArrayList<String>();
            perm.add("user_friends");
            LoginManager.getInstance().logInWithReadPermissions(activity, perm);
        }
    });
}

登录后，不会触发 onSuccess()、onCancel()、onError() 方法。

我的活动中缺少这个：

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