如何配置 Firebase Auth 對話框的超鏈接

Question

使用 Firebase 身份驗證的 Google 登錄方法時，隱私政策和服務條款的超鏈接不起作用。 請注意，在某些設備上沒有超鏈接。 我關注了文檔： https://firebase.google.com/docs/auth/android/google-signin

活動：

public class MainActivity extends AppCompatActivity {

    GoogleSignInClient mGoogleSignInClient;
    private int RC_SIGN_IN =10996;
    private FirebaseAuth mAuth;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        createRequest();
        // Initialize Firebase Auth
        mAuth = FirebaseAuth.getInstance();

        findViewById(R.id.loginId).setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                openSomeActivityForResult();
            }
        });
    }

    private void createRequest() {

        GoogleSignInOptions gso = new GoogleSignInOptions
                .Builder(GoogleSignInOptions.DEFAULT_SIGN_IN)
                .requestIdToken(getString(R.string.default_web_client_id))
                .requestEmail()

                @Override
                public void onActivityResult(ActivityResult result) {
                    if (result.getResultCode() == Activity.RESULT_OK) {
                        Intent data = result.getData();

        FirebaseUser currentUser = mAuth.getCurrentUser();
        if(currentUser!=null){

            startActivity(new Intent(MainActivity.this,SignOut.class));

請注意， onActivityResult已棄用。 您應該做的是使用registerForActivityResult 。 在 Java 中，它應該是這樣的：

ActivityResultLauncher<Intent> someActivityResultLauncher = registerForActivityResult(
        new ActivityResultContracts.StartActivityForResult(),
        new ActivityResultCallback<ActivityResult>() {
            @Override
            public void onActivityResult(ActivityResult result) {
                if (result.getResultCode() == Activity.RESULT_OK) {
                    Intent data = result.getData();
                    //Do that you need to do with the data
                }
            }
        });

public void openSomeActivityForResult() {
    Intent intent = new Intent(this, SomeActivity.class);
    someActivityResultLauncher.launch(intent);
}
