数据未保存在firebase中的实时数据库中

Question

我已经创建了用户配置文件并与 fireabse 连接，但保存 btn 数据后未显示我在 firebase 中的实时数据库

我已经尝试了很多次并且

这是提供的实时数据库规则

  "rules": {
    ".read": "auth != null",
    ".write": "auth != null"
  }
}

btnsaveprofile.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                username = edtxtusername.getText().toString().trim();
                profession = spinnerprofession.getSelectedItem().toString();

                if (username.isEmpty()){
                    Toast.makeText(getApplicationContext(), "Please Enter Your Name", Toast.LENGTH_SHORT).show();
                } else if (profession.equals(getString(R.string.select_profession))) {
                    Toast.makeText(getApplicationContext(), "Please Select Your Profession", Toast.LENGTH_SHORT).show();
                } else {

                    mprogressbarofsaveprofile.setVisibility(View.VISIBLE);
                    btnsaveprofile.setVisibility(View.INVISIBLE);

                    firebaseAuth = FirebaseAuth.getInstance();
                    databaseReference = FirebaseDatabase.getInstance().getReference("users");
                    String userId = databaseReference.push().getKey();
                    User user = new User(username, profession);
                    
                    databaseReference.child(userId).setValue(user);

                    Toast.makeText(getApplicationContext(), "Success", Toast.LENGTH_SHORT).show();
                    Intent intent = new Intent(getApplicationContext(), NexusHome.class);
                    intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_CLEAR_TASK);
                    startActivity(intent);


                    btnsaveprofile.setVisibility(View.VISIBLE);
                    mprogressbarofsaveprofile.setVisibility(View.INVISIBLE);
                }
            }
        });

这是 User.class java 代码

public class User {
    private String username;
    private String profession;

    public User() {
    }
    public User(String username, String profession) {
        this.username = username;
        this.profession = profession;

    }

    public String getUsername() {
        return username;
    }

    public void setUsername(String username) {
        this.username = username;
    }
    public String getProfession() {
        return profession;
    }
    public void setProfession(String profession) {
        this.profession = profession;
    }
}

请帮助我更正此代码，我可以将数据保存在 firebase 中吗
