Question

修改：问题图片，http://imgur.com/a/N4pRb

使用Facebook登录时，我会弹出提示用户登录，这会将我带到一个“确认登录”页面，上面写着我的应用程序已被授权。我单击确定，它会将我带回初始登录弹出窗口。当我单击左上角的“x”时，我的onSuccess（）代码运行。登录完成后，onSuccess（）方法应处理登录并将用户带到另一个活动。我从哪里开始？

MainActivity，

    @Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    Fragment fragment = getSupportFragmentManager().findFragmentById(R.id.content_main);
    fragment.onActivityResult(requestCode, resultCode, data);
}

LoginFragment，

public class LoginFragment extends MvpFragment<LoginView, LoginPresenter> implements LoginView, View.OnClickListener {

private EditText _userName;
private EditText _password;
private Button _loginWithFacebook;
private CallbackManager _callbackManager;
private static final String TAG = LoginFragment.class.getSimpleName();


@Nullable
@Override
public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {
    View view = inflater.inflate(R.layout.fragment_login, container, false);

    view.findViewById(R.id.login_btn).setOnClickListener(this);
    view.findViewById(R.id.login_forgot_password).setOnClickListener(this);
    view.findViewById(R.id.login_signup).setOnClickListener(this);
    view.findViewById(R.id.login_skip).setOnClickListener(this);

    _userName = (EditText) view.findViewById(R.id.login_username);
    _password = (EditText) view.findViewById(R.id.login_password);

    _loginWithFacebook = (Button) view.findViewById(R.id.facebook_login_button);
    _loginWithFacebook.setOnClickListener(this);

    LoginManager.getInstance().logOut();

    return view;
}

@NonNull
@Override
public LoginPresenter createPresenter() {
    return new LoginPresenterImpl((LoginRouter) getActivity(), new PreferencesManager(getContext()));
}

@Override
public void authenticationError() {
    AlertDialogFragment.newInstance(R.string.login_authentication_error, false).show(getChildFragmentManager(), null);
}

@Override
public void onShowEmptyFieldError() {
    AlertDialogFragment.newInstance(R.string.login_empty_field_error, false).show(getChildFragmentManager(), null);
}

@Override
public void onClick(View v) {
    switch (v.getId()) {
        case R.id.facebook_login_button:
            //presenter.onFacebookLoginClick();
            facebookLogIn();
            break;
        case R.id.login_btn:
            doLogin();
            break;
        case R.id.login_forgot_password:
            presenter.onForgotPasswordClick();
            break;
        case R.id.login_signup:
            presenter.onSignUpClick();
            break;
        case R.id.login_skip:
            presenter.onSkipForNowClick();
            break;
    }
}


private void doLogin() {
    presenter.onLocalLoginClick(_userName.getText().toString().trim(),
            _password.getText().toString().trim());
}

@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    if (_callbackManager != null) {
        _callbackManager.onActivityResult(requestCode, resultCode, data);
    }

                                        }
                                    })
                    );

                    batch.executeAsync();

                }

                @Override
