android - 匿名登录和用户名 : Firebase + AuthUI

Question

我是 Firebase 和 Firebase Auth UI 的新手，有两个问题:

1. 我正在使用 Firebase Auth UI 进行简单的登录 Activity 。如何在屏幕上添加匿名登录选项？该选项在 Firebase 控制台中激活。
2. 如何为用户添加用户名/昵称？注册完成后添加是可以的，但是我必须调用哪个方法？

这是我的代码:

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

        FirebaseAuth auth = FirebaseAuth.getInstance();
        if (auth.getCurrentUser() != null) {
            // User is already signed in
            Intent intent = new Intent(LoginActivity.this, MainActivity.class);
            startActivity(intent);
        } else {
            // User isn't already signed in
            startActivityForResult(
                    AuthUI.getInstance()
                            .createSignInIntentBuilder()
                            .setProviders(
                                    AuthUI.EMAIL_PROVIDER,
                                    AuthUI.GOOGLE_PROVIDER)
                            .setLogo(R.mipmap.ic_launcher)
                            .build(),
                    RC_SIGN_IN);
            }
}

protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        super.onActivityResult(requestCode, resultCode, data);
        if (requestCode == RC_SIGN_IN) {
            if (resultCode == RESULT_OK) {
                // user is signed in!
                startActivity(new Intent(this, MainActivity.class));
                finish();
            } else {
                Toast.makeText(LoginActivity.this, "Error during login :(", Toast.LENGTH_SHORT).show();
            }
        }
    }

Answer 1

您可以从 link 中找到所有可能的 Firebase 登录实现.

Q1. I am using Firebase Auth UI for a simple login activity. How can I add a anonymous login option to the screen? The option is activated in the Firebase console.

../AnonymousAuthActivity.java

Q2. How can I add a username / nickname to the user? It is okay to add it after the registration completed, but which method do I have to call?

.../EmailPasswordActivity.java
