android - 在 firebase 中更新用户的显示名称(android)

Question

我正在为登录屏幕创建一个带有 firebase 的项目。我正在尝试使用下面的代码更新用户的显示名称，但它没有更新显示名称。帮帮我

FirebaseUser user = FirebaseAuth.getInstance().getCurrentUser();
        UserProfileChangeRequest profileUpdates = new UserProfileChangeRequest.Builder()
                .setDisplayName(name)
                .build();
        user.updateProfile(profileUpdates).addOnCompleteListener(new OnCompleteListener<Void>() {
            @Override
            public void onComplete(@NonNull Task<Void> task) {
                if(task.isSuccessful()){
                    Toast.makeText(VerifyUser.this,"Name updated successfully",Toast.LENGTH_LONG).show();
                    startActivity(new Intent(VerifyUser.this,MainActivity.class));
                }else
                    Toast.makeText(VerifyUser.this,"Name update Failed",Toast.LENGTH_LONG).show();
            }
        });

您需要在登录或验证电子邮件和密码后立即更新用户资料。

我知道我来晚了，但为了后代，要在 firebase 上更新用户属性，他们需要先登录。

所以像这样:

 mAuth.signInWithCredential(credential)
            .addOnCompleteListener(LordRegister.this,
                    new OnCompleteListener<AuthResult>() {

                        @Override
                        public void onComplete(@NonNull Task<AuthResult> task) {
                            if (task.isSuccessful()) {
                                //verification successful we will start the profile activity
                                FirebaseUser user = task.getResult().getUser();
                                String name = nameInput.getText().toString().trim();
                                //user.updateProfile()
                                UserProfileChangeRequest profileUpdates = new UserProfileChangeRequest.Builder()
                                        .setDisplayName(name)
                                        .build();
                                user.updateProfile(profileUpdates).addOnCompleteListener(new OnCompleteListener<Void>() {
                                    @Override
                                    public void onComplete(@NonNull Task<Void> task) {
                                        if(task.isSuccessful()){
                                            Intent intent = new Intent(LordRegister.this, LordHome.class);
                                            intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_CLEAR_TASK);
                                            startActivity(intent);
                                        }else
                                            Toast.makeText(LordRegister.this,"Name update Failed, try again",Toast.LENGTH_LONG).show();
                                    }
                                });

                            } else {

                                //verification unsuccessful.. display an error message

                                String message = "Somthing is wrong, we will fix it soon...";

                                if (task.getException() instanceof FirebaseAuthInvalidCredentialsException) {
                                    message = "Invalid code entered...";
                                }
                                Toast.makeText(LordRegister.this,message,Toast.LENGTH_SHORT).show();
                            }
                        }
                    });
}

像上面一样，我使用用户电话号码登录或先验证用户，然后更新名称或任何其他属性。
