Question

我尝试按照Google登录的片段进行操作，但不是将其放在活动上，而是在片段上使用它。它只适用于牛轧糖。问题似乎依赖于给予谷歌的意图。每当我点击Google中的标志时，它都会关闭我的应用。

对话框出现在我的应用程序之外，并且它没有回到我的片段。它只是关闭了。

所以这是我的代码：它与代码段几乎相同。但问题是，当我点击Google登录时应用程序关闭时，它允许用户每次都选择电子邮件，但它不会返回到onActivityResult，因为我的logcat上没有记录数据

public class LoginFragment extends Fragment implements OnConnectionFailedListener {
    private FragmentManager fragmentManager;
    private FragmentTransaction fragmentTransaction;
    private Button signUp, login;
    private View view;
    private SharedPref pref;


    private SignInButton signInButton;
    private GoogleSignInOptions gso;
    private GoogleApiClient mGoogleApiClient;
    private int RC_SIGN_IN = 0;
    private static final String TAG = "GPlusFragment";

    private Retrofit retrofit;
    private RequestInterface requestInterface;
    private ServerRequest request;
    private boolean connectionError = false;
    @Override

        super.onCreate(savedInstanceState);

        gso = new GoogleSignInOptions.Builder(GoogleSignInOptions.DEFAULT_SIGN_IN)
                .requestEmail()
                .requestProfile()
                .build();

        mGoogleApiClient = new GoogleApiClient.Builder(getActivity())
                .enableAutoManage(getActivity() /* FragmentActivity */, this /* OnConnectionFailedListener */)
                .addApi(Auth.GOOGLE_SIGN_IN_API, gso)

        login = (Button) view.findViewById(R.id.login);
        fragmentManager = getFragmentManager();


        //Initializing signinbutton
        signInButton = (SignInButton) view.findViewById(R.id.google_sign_in_button);
        signInButton.setSize(SignInButton.SIZE_WIDE);

        return view;

                startActivityForResult(signInIntent, RC_SIGN_IN);
            }
        });
    }

    private void handleSignInResult(GoogleSignInResult result) {

        if (result.isSuccess()) {
             //my code here doing the login
