Question

我不知道自己的代码有什么问题，它不会给我任何错误消息。

这是以下代码：SignInFragment

public class SignInFragment extends Fragment implements View.OnClickListener {

private static final String TAG = "email";

private TextView mEmail, mPassword, mHeading, mToRegister, mFckyou;
private EditText eEmail, ePassword;
private Button btnSignin;
private ProgressBar mProgressBar;

//Firebase
private FirebaseAuth mAuth;
private FirebaseAuth.AuthStateListener mAuthListener;

//Facebook
private CallbackManager callbackManager;
private LoginButton loginButton;
@Nullable
@Override
public View onCreateView(@NonNull LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {
    View view = inflater.inflate(R.layout.signin_fragment, container, false);

    //TextView
    mEmail = view.findViewById(R.id.tvEmail);
    mPassword = view.findViewById(R.id.tvPassword);
    mHeading = view.findViewById(R.id.heading);
    mToRegister = view.findViewById(R.id.toRegister);
    mFckyou = view.findViewById(R.id.fckyou);
    //EditText
    eEmail = view.findViewById(R.id.etEmail);
    ePassword = view.findViewById(R.id.etPassword);
    //Changing the font style of hint
    eEmail.setTypeface(Typeface.SANS_SERIF);
    ePassword.setTypeface(Typeface.SANS_SERIF);
    //Button
    btnSignin = view.findViewById(R.id.btnSignin);
    //ProgressBar
    mProgressBar = view.findViewById(R.id.progressBar);
    //Facebook
    loginButton = view.findViewById(R.id.login_button);
    //Firebase
    mAuth = FirebaseAuth.getInstance();

    //Progress Bar and Text view = GONE
    mProgressBar.setVisibility(View.GONE);
    mFckyou.setVisibility(View.GONE);

    setupFbAuth();
    navigateToReigster();
    setupFirebaseAuth();
    signInUser();

    return view;
}

Answer 1

如下更改 readPermissions ：

使用：

loginButton.setReadPermissions("email", "public_profile");

而不是：

loginButton.setReadPermissions(Arrays.asList("email"));

它为您工作。祝您好运！
