Question

我在我的应用程序中使用facebook集成登录。我使用了facebook SDK 4.2。一切正常。按下登录按钮后，Facebook会提示登录，然后是权限页面。但是一旦我给予许可，没有回拨是在代码中调用，即使提供了权限，因为我可以在我的facebook帐户中查看.Below是回调代码

public void onActivityCreated(@Nullable Bundle savedInstanceState) {

    super.onActivityCreated(savedInstanceState);
    loginButton = (LoginButton) getView().findViewById(R.id.connectWithFbButton);
    loginButton.setCompoundDrawablePadding(50);
    List<String> permissionNeeds = Arrays.asList("user_photos", "email", "user_birthday", "public_profile");
    loginButton.setReadPermissions(permissionNeeds);
    loginButton.setFragment(this);

    loginButton.registerCallback(callbackManager, new FacebookCallback<LoginResult>() {
        @Override
        public void onSuccess(LoginResult loginResult) {
            System.out.println("onSuccess");
            Log.v("LoginActivity", "onSuccess");

            AccessToken token = loginResult.getAccessToken();

            GraphRequest request = GraphRequest.newMeRequest
                    (loginResult.getAccessToken(), new GraphRequest.GraphJSONObjectCallback() {
                        @Override
                        public void onCompleted(JSONObject object, GraphResponse response) {
                            // Application code
                            //  Log.v("LoginActivity", response.toString());
                            System.out.println("Check: " + response.toString());
                            try {
                                String id = object.getString("id");
                                String name = object.getString("name");
                                String email = object.getString("email");
                                String gender = object.getString("gender");
                                String birthday = object.getString("birthday");


                                Toast.makeText(getActivity(), "Logged In", Toast.LENGTH_SHORT);
                                System.out.println(id + ", " + name + ", " + email + ", " + gender + ", " + birthday);
                            } catch (JSONException e) {
                                e.printStackTrace();
                            }

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

        @Override
        public void onCancel() {
            System.out.println("onCancel");
        }

        @Override
        public void onError(FacebookException exception) {
            System.out.println("onError");

        }
    });

}`

我也覆盖了onActivityResult（）;

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

请建议任何解决方案？

注意：我在片段

中使用了这段代码

Answer 1

我发现解决方案.FB回调没有进入片段。当我移动整个代码时，活动回调开始被调用。它在片段内部不起作用。

在android facebook SDK中没有调用回调
