                @Override

                        FirebaseDatabase.getInstance().getReference("Users")
                                .child(FirebaseAuth.getInstance().getCurrentUser().getUid())

                    }
                }
            });
    }
}

问题根源与修复步骤

  • 核心错误：控件类型不匹配
    代码中registerUser被声明为TextView，但实际是布局中的Button，强转错误会导致点击事件绑定失效，后续注册逻辑完全不执行，ProgressBar一直处于显示状态。
    修复：将private TextView registerUser;改为private Button registerUser;

  • 冗余校验清理
    代码中重复判断password.isEmpty()，删除其中一处即可，避免逻辑冗余。

  • UI操作线程安全优化
    虽然Firebase的onComplete默认在主线程执行，但显式使用runOnUiThread包裹Toast和ProgressBar操作，可避免潜在的线程异常问题。

  • 添加异常信息捕获
    在失败分支中获取task.getException().getMessage()，能显示具体错误原因，便于排查注册失败问题（如邮箱已存在、网络异常等）。

修复后的Java代码 

private Button registerUser;
private EditText editTextUserName, editTextEmail, editTextPassword;
private ProgressBar progressBar;

private FirebaseAuth mAuth;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    registerUser = findViewById(R.id.button_daftar);
    registerUser.setOnClickListener(this);

    editTextUserName = findViewById(R.id.textuserregis);
    editTextEmail = findViewById(R.id.textregisemail);
    editTextPassword = findViewById(R.id.textregispassword);

    progressBar = findViewById(R.id.progressBar);
}

@Override
public void onClick(View v) {
    switch (v.getId()) {
        case R.id.button_daftar:
            registerUser();
            break;
    }
}

private void registerUser() {
    String fullName = editTextUserName.getText().toString().trim();
    String email = editTextEmail.getText().toString().trim();
    String password = editTextPassword.getText().toString().trim();

    if (fullName.isEmpty()) {
        editTextUserName.setError("Isi username anda");
        editTextUserName.requestFocus();
        return;
    }

    if (email.isEmpty()) {
        editTextEmail.setError("Isi email anda");
        editTextEmail.requestFocus();
        return;
    }

    if (!Patterns.EMAIL_ADDRESS.matcher(email).matches()) {
        editTextEmail.setError("mohon gunakan email yang valid (contoh = seseorang@gmail.com)");
        editTextEmail.requestFocus();
        return;
    }

    if (password.isEmpty()) {
        editTextPassword.setError("Mohon atur password anda");
        editTextPassword.requestFocus();
