Google+ 登录在 Android 片段上无法正常工作

我正在使用 google+ 登录我的应用程序，当我使用活动完成它的工作魅力之后，我将代码移动到片段中，之后当我尝试登录 google+ 时，它不起作用，我必须打开片段活动2 次登录 google+ 谁能告诉我发生了什么代码片段添加在下面

public class GooglePluseFragment extends Fragment implements
        ConnectionCallbacks, OnConnectionFailedListener {

private static final int RC_SIGN_IN = 0;

private static final String TAG = "MainActivity";

private static final int PROFILE_PIC_SIZE = 800;

private GoogleApiClient mGoogleApiClient;

private boolean mIntentInProgress;

private boolean mSignInClicked;

private ConnectionResult mConnectionResult;

private Button btnSignOut;

private Activity mActivity;



@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    mActivity = getActivity();
    mContext = getActivity().getApplicationContext();
}

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
        Bundle savedInstanceState) {

    View view = inflater.inflate(R.layout.compund_google_pluse_fragment,
            container, false);

    btnSignIn = (SignInButton) view.findViewById(R.id.btn_sign_in);

            String personName = currentPerson.getDisplayName();
            String personPhotoUrl = currentPerson.getImage().getUrl();
            String personGooglePlusProfile = currentPerson.getUrl();

            Log.e(TAG, "Name: " + personName + ", plusProfile: "

        } else {
            Toast.makeText(mContext, "Person information is null",
                    Toast.LENGTH_LONG).show();

        updateUI(false);

    }
}

}

这就是我在片段活动中添加framgent的方式

pluseFragment = new GooglePluseFragment();

        FragmentManager manager = getSupportFragmentManager();

        FragmentTransaction transaction = manager.beginTransaction();
transaction.add(R.id.pluse_frame_layout, pluseFragment);
transaction.commit();

有人可以告诉我我做错了什么吗？为什么我必须打开活动两次才能登录谢谢

终于找到了答案，问题是当片段中的结果活动调用被父活动捕获时，因此您必须手动将结果重定向到片段。只需在您的父片段活动中添加这一行

@Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {

        if (requestCode == GooglePluseFragment.RC_SIGN_IN) {
            GooglePluseFragment fragment = (GooglePluseFragment) getSupportFragmentManager()
                    .findFragmentById(R.id.pluse_frame_layout);
            fragment.onActivityResult(requestCode, resultCode, data);
        } else {
            super.onActivityResult(requestCode, resultCode, data);
        }
    }
