如何在数据库（Firebase）中进行身份验证后保存用户的电子邮件和姓名？

Question

我是 Android 新手，也是 Firebase 新手。我正在开发一个 Android 应用程序，用户使用电子邮件和密码创建他的帐户。

如何将用户身份（如姓名、地址等）连同电子邮件一起保存到 Firebase 数据库中？

这是我的代码，其中用户是使用电子邮件和密码创建的，以及有关要保存在数据库中的用户的额外信息的代码。

我的应用在创建新用户后崩溃了，而且它没有在数据库中存储信息。

auth.createUserWithEmailAndPassword(emailId, password)
    .addOnCompleteListener(MainActivity.this, new OnCompleteListener<AuthResult>() {
        @Override
        public void onComplete(@NonNull Task<AuthResult> task) {

                if (task.isSuccessful()) {

                    String user_id = auth.getCurrentUser().getUid();

                    DatabaseReference current_user_db = reference.child(user_id);

                    current_user_db.child("FNAME").setValue(nameF);

                    current_user_db.child("LNAME").setValue(nameL);

                    current_user_db.child("EMAIL").setValue(email);

                    progress.hide();

                    Intent intent = new Intent(MainActivity.this, ProfileActivity.class);

                    intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);

                    startActivity(intent);

                }

        }
    });

这是日志。

尝试使用 HashMap（个人认为我觉得它更具可读性）这是我更新用户设置的代码，整个函数通过一个按钮被调用，希望这会有所帮助。

private void updatesettings() {
    String UserName = username.getText().toString().toLowerCase().trim();
    String PhoneNumber= pno.getText().toString();

    FirebaseUser user = mauth.getCurrentUser();
    String uid = user.getUid();

    //this is to enter all the details under the UID of currently logged in user

    dbr = FirebaseDatabase.getInstance().getReference().child("Users").child(uid);

    HashMap<String, String> userMap = new HashMap<String, String>();
    userMap.put("name", UserName);
    userMap.put("phone number", PhoneNumber);
    userMap.put("status", "jdjdjjdjdjdj");
    userMap.put("image", "default");
    userMap.put("thumbnail", "default");

    dbr.setValue(userMap).addOnCompleteListener(new OnCompleteListener<Void>() {
        @Override
        public void onComplete(@NonNull Task<Void> task) {
            if(task.isSuccessful()){
                // Toast.makeText(UpdateUserSettings.this, "Your settings have been updated", Toast.LENGTH_LONG).show();
                startActivity(new Intent(UpdateUserSettings.this, MainActivity.class));
            }
            else{
                Toast.makeText(UpdateUserSettings.this, task.getException().getMessage(), Toast.LENGTH_LONG).show();
            }
        }
    });
}
