為了確認火壘身份驗證狀態列表（）正在啟動。這是來自我的登錄類的糟糕的復制和粘貼作業。這阻止了我處理成功的用戶創建。
然后修復程序如下所示：
public class Register extends AppCompatActivity {
private EditText mEmailField;
private EditText mPasswordField;
private EditText mConfirmPassword;
private Button mRegisterButton;
private FirebaseAuth mAuth;
private FirebaseAuth.AuthStateListener mAuthListener;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
FirebaseApp.initializeApp(this);
setContentView(R.layout.activity_register);
mEmailField = findViewById(R.id.registerEmailField);
mPasswordField = findViewById(R.id.registerPasswordField);
mConfirmPassword = findViewById(R.id.registerConfirmPassword);
mRegisterButton = findViewById(R.id.registerButton);
mAuth = FirebaseAuth.getInstance();
// https://stackoverflow.com/questions/10936042/how-to-open-layout-on-button-click-android
Button register = (Button) findViewById(R.id.navigate_to_login);
register.setOnClickListener(new View.OnClickListener() {
public void onClick(View view) {
Intent myIntent = new Intent(view.getContext(), Login.class);
startActivityForResult(myIntent, 0);
}
});
mRegisterButton.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
startRegister();
}
});
}
@Override
protected void onStart() {
super.onStart();
}
private void startRegister() {
String email = mEmailField.getText().toString();
String password = mPasswordField.getText().toString();
String confirmPassword = mConfirmPassword.getText().toString();
// Check that fields are not empty
if (TextUtils.isEmpty(email) || TextUtils.isEmpty(password) || TextUtils.isEmpty(confirmPassword)) {
Toast.makeText(Register.this, "Email, password or confirm password field cannot be empty.", Toast.LENGTH_LONG).show();
} else if (!password.equals(confirmPassword)) {
Toast.makeText(Register.this, "Password and confirm password should match", Toast.LENGTH_LONG).show();
} else {
mAuth.createUserWithEmailAndPassword(email, password).addOnCompleteListener(new OnCompleteListener<AuthResult>() {
