我无法将用户数据从注册活动代码发送到实时。我尝试了不同的方法，并确保所有连接都是正确的，但信息仍然没有到达实时。我正在使用的Gmail只能达到身份验证。我怀疑问题出在我的代码上。下面是相关的代码片段：
java注册

private FirebaseAuth mAuth;
private FirebaseAuth.AuthStateListener authStateListener;

ActivitySignUpBinding binding;
DatabaseReference usersRef = FirebaseDatabase.getInstance().getReference("Users");

ProgressDialog dialog;
EditText emailEditText;
EditText passwordEditText;
EditText phoneEditText;
EditText firstNameEditText;
EditText lastNameEditText;
EditText CompassE;
private String email;
private String password;
private String phone;
private String firstName;
private String lastName;
private String repass;

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

    mAuth = FirebaseAuth.getInstance();
    dialog = new ProgressDialog(sign_up.this);
    dialog.setTitle("Created Account");
    dialog.setMessage("We created your account");

    binding = ActivitySignUpBinding.inflate(getLayoutInflater());
    setContentView(binding.getRoot());

    emailEditText = binding.Textemail;
    passwordEditText = binding.Textpass;
    phoneEditText = binding.Textphone;
    firstNameEditText = binding.Textname;
    lastNameEditText = binding.Textlast;
    CompassE = binding.repass;



    findViewById(R.id.button1).setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            email = emailEditText.getText().toString().trim();
            password = passwordEditText.getText().toString().trim();
            phone = phoneEditText.getText().toString().trim();
            firstName = firstNameEditText.getText().toString().trim();
            lastName = lastNameEditText.getText().toString().trim();
            repass = CompassE.getText().toString().trim();

            

            // Registration logic
            mAuth.createUserWithEmailAndPassword(email, password)
                    .addOnCompleteListener(new OnCompleteListener<AuthResult>() {
                        @Override
                        public void onComplete(@NonNull Task<AuthResult> task) {
                            if (task.isSuccessful()) {
                                String userId = mAuth.getCurrentUser().getUid();
                                String email = emailEditText.getText().toString();
                                String refer = email.substring(0, email.lastIndexOf("@"));
                                String referCode = refer.replace(".", "");

                                DatabaseReference usersRef = FirebaseDatabase.getInstance().getReference("Users");

                                HashMap<String, Object> map = new HashMap<>();
                                map.put("name", firstNameEditText.getText().toString());
                                map.put("phone", phoneEditText.getText().toString());

                                map.put("password", passwordEditText.getText().toString());
                                map.put("refer code", referCode);

                                map.put("cis", 20);
                                map.put("sps", 4);

                                // Send the data to the database
                                usersRef.child(mAuth.getCurrentUser().getUid()).setValue(map);

                                Intent intent = new Intent(sign_up.this, testMain.class);
                                startActivity(intent);
                                finish();

                                Toast.makeText(sign_up.this, "Your account has been created", Toast.LENGTH_SHORT).show();
                                DatabaseReference databaseRef = FirebaseDatabase.getInstance().getReference("Users");

                            } else {

                        }
                    });

用户Java类
