Android Facebook 使用 LoginManager & 设置权限

Question

我正在尝试使用 LoginManager 并在用户登录时设置权限。我希望 publish_actions 对用户可用。

我像这样使用 LoginManager:

    LoginManager.getInstance().registerCallback(callbackManager, new FacebookCallback<LoginResult>() {
        @Override
        public void onSuccess(LoginResult loginResult) {
            final AccessToken accessToken = loginResult.getAccessToken();
            GraphRequestAsyncTask request = GraphRequest.newMeRequest(accessToken, new GraphRequest.GraphJSONObjectCallback() {
                @Override
                public void onCompleted(JSONObject user, GraphResponse graphResponse) {
                    //Do stuff when the login is complete
                }
            }).executeAsync();
        }

        @Override
        public void onCancel() {
            Toast.makeText(getApplicationContext(), "Facebook Login Cancelled", Toast.LENGTH_LONG).show();
        }

        @Override
        public void onError(FacebookException exception) {
            Toast.makeText(getApplicationContext(), "Facebook Login Error", Toast.LENGTH_LONG).show();
        }
    });

现在，我想添加一个权限行:

LoginManager.getInstance().logInWithPublishPermissions(StartPage.this, Arrays.asList("publish_actions"));

虽然我不确定把它放在哪里。当我把它放在第一个 LoginManager 之外(之前或之后)时，我得到了一些登录 facebook 的无限循环，并且 facebook 模式说“你已经允许我的应用程序”。

使用LoginManager时如何设置权限？另外，有没有办法在登录时不显示“您已经允许此应用”屏幕？

为清楚起见，

更新。

protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);
    FacebookSdk.sdkInitialize(this.getApplicationContext());
    setContentView(R.layout.activity_start_page);
    callbackManager = CallbackManager.Factory.create();

    ...

    final LoginButton loginButton = (LoginButton) view.findViewById(R.id.login_button);
    loginButton.setReadPermissions("user_friends");
    // If using in a fragment
    //loginButton.setFragment();
    // Other app specific specialization

    // Callback registration
    loginButton.registerCallback(callbackManager, new FacebookCallback<LoginResult>() {
        @Override
        public void onSuccess(LoginResult loginResult) {
            final AccessToken accessToken = loginResult.getAccessToken();
            GraphRequestAsyncTask request = GraphRequest.newMeRequest(accessToken, new GraphRequest.GraphJSONObjectCallback() {
                @Override
                public void onCompleted(JSONObject user, GraphResponse graphResponse) {
                    loginButton.clearPermissions();
                    loginButton.setPublishPermissions(Arrays.asList("publish_actions"));

                    facebook_id = user.optString("id");
                    facebook_name.setText(user.optString("name"));
                    facebook_name.setVisibility(View.VISIBLE);
                    exc_share_facebook.setVisibility(View.GONE);
                    share_facebook_user.setVisibility(View.VISIBLE);
                    share_facebook_auto.setVisibility(View.VISIBLE);
                    profilePictureView.setProfileId(user.optString("id"));
                }
            }).executeAsync();
        }

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

        @Override
        public void onError(FacebookException exception) {
            // App code
        }
    });
}
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    callbackManager.onActivityResult(requestCode, resultCode, data);

}

你不能同时授予读取和发布权限，先授予读取权限，然后再请求发布权限

_loginfb=(LoginButton)findViewById(R.id.fblogin);

    _loginfb.setReadPermissions(mReadPermissions);

    _loginfb.registerCallback(callbackManager, new FacebookCallback<LoginResult>() {
        @Override
        public void onSuccess(LoginResult loginResult) {

            final Bundle params = new Bundle();
            params.putString("fields", "id, email, name, picture.type(large)");

            System.out.println("Success callback");
            GraphRequest mRequest = GraphRequest.newMeRequest(
                    loginResult.getAccessToken(), new GraphRequest.GraphJSONObjectCallback() {
                        @Override
                        public void onCompleted(JSONObject json, GraphResponse response) {
                            _loginfb.clearPermissions();
                            _loginfb.setPublishPermissions(mPublishPermissions);
                            if (response.getError() != null) {
                                // handle error

                            } else {

                                String jsonresult = String.valueOf(json);



                            }
                        }
                    });
            mRequest.setParameters(params);
            mRequest.executeAsync();

        }

        @Override
        public void onCancel() {

        }


    @Override
    public void onError(FacebookException error) {
        // TODO Auto-generated method stub
        System.out.println(error);
    }
});
