【问题描述】：

我是火力基地的新手。我试图将我的应用程序中列出的用户的属性保存到数据库Firebase，这是代码

mAuthListener = new FirebaseAuth.AuthStateListener() {
        @Override
        public void onAuthStateChanged(@NonNull FirebaseAuth firebaseAuth) {
            firebaseuser = firebaseAuth.getCurrentUser();
            if (firebaseuser != null) {
                finish();
                firebaseuser = mAuth.getCurrentUser();
                String nama = firebaseuser.getDisplayName();
                String mail = firebaseuser.getEmail();
                //String pass = password.getText().toString();
                String id = firebaseuser.getUid();
                //Uri gambar = firebaseuser.getPhotoUrl();
                member1 = new Member(nama, mail, "", "belum", "belum", "belum", id);
                datab.getReference("member").push().setValue(member1);
                startActivity(new Intent(getApplicationContext(), HalamanUtama.class));
            }
        }
    };

这里的问题是当我使用谷歌登录进入我的应用程序时，我无法将使用谷歌登录到我的应用程序的用户的信息保存到我的 firebase 数据库中，但我可以使用保存用户的登录信息电子邮件方法。这是使用电子邮件进入我的应用程序的代码

mAuth.createUserWithEmailAndPassword(email.getText().toString(), password.getText().toString())
                        .addOnCompleteListener(HalamanPendaftaran.this, new OnCompleteListener<AuthResult>() {
                            @Override
                            public void onComplete(@NonNull Task<AuthResult> task) {
                                if (task.isSuccessful()) {
                                    progressdialog.dismiss();
                                    finish();
                                    firebaseuser = mAuth.getCurrentUser();
                                    String nama = firebaseuser.getDisplayName();
                                    String mail = firebaseuser.getEmail();
                                    String pass = password.getText().toString();
                                    String id = firebaseuser.getUid();
                                    Uri gambar = firebaseuser.getPhotoUrl();
                                    member1 = new Member(nama, mail, pass, "belum", "belum", "belum", id, gambar);
                                    datab.getReference("member").push().setValue(member1);
                                    startActivity(new Intent(HalamanPendaftaran.this, HalamanUtama.class));
                                } else {
                                    progressdialog.dismiss();
                                    Toast.makeText(HalamanPendaftaran.this, "tidak dapat mendaftarkan user, tolong coba lagi !", Toast.LENGTH_SHORT).show();
                                    email.setText("");
                                    password.setText("");
                                }
                            }
                        });

至于我在尝试存储使用谷歌登录的用户数据时遇到的错误

这是成功保存的用户的数据之一 Firebase Database data

任何帮助将不胜感激

【问题讨论】：

我没有发现任何错误，但我想知道你为什么这么早就打电话给finish()？
em，用于在活动之间移动。问题出在代码“datab.getReference("member").push().setValue(member1);"
我知道它的用途，但我只是想知道为什么你在代码的早期而不是之后调用它。我认为你不应该这么早打电话给finish()。在实际开始新活动后尝试调用它。
哦好的我改一下，问题还没解决
您还获得了当前用户两次。在您检查 user != null 之前和之后一次。你能提供你的Member.class吗？我想这有什么问题。

【解决方案1】：

您的Member 类包含Uri 类型的字段。 Uri 不是 Firebase 序列化的 one of the native types。

更改您的 Member 类以将 Uri 存储为字符串并使用 Uri.toString() 和 Uri.parse() 进行转换。

非常感谢，因为这个，我整晚都在拉扯我的头发。 Firebase 应该生成更易于理解的错误消息，而不是向这一行发送垃圾邮件com.google.android.gms.internal.zzbqi$zza
