Firebase createUser使用电子邮件和密码任务.isSuccessful（）

Question

我正在创建一个安卓应用程序，并正在实现登录/注册功能。

我正处于注册活动在我的Firebase应用程序中成功创建用户条目的阶段，但是，我似乎无法跟踪任务是否成功。

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).addOnSuccessListener(new OnSuccessListener<AuthResult>() {

            @Override

            public void onSuccess(AuthResult authResult) {

                Toast.makeText(Register.this, "Success", Toast.LENGTH_LONG).show();

            }

        }).addOnFailureListener(new OnFailureListener() {

            @Override

            public void onFailure(@NonNull Exception e) {

                Toast.makeText(Register.this, "Failure", Toast.LENGTH_LONG).show();

            }

        });

    }

}

如果 ！task.是成功的（） 或者块曾经被到达，但用户是在火库中创建的。任何想法为什么我不能跟踪成功/如果它失败了？

相比之下：

这在我的登录类中起作用。

        mAuth.signInWithEmailAndPassword(email, password).addOnCompleteListener(new OnCompleteListener<AuthResult>() {

            @Override

            public void onComplete(@NonNull Task<AuthResult> task) {

                if (!task.isSuccessful()) {

                    Toast.makeText(Login.this, "Credentials error, user may not exist.", Toast.LENGTH_LONG).show();

                }

            }

        });

很难说目前的实施方式是怎么回事。尝试直接添加成功mAuth.createUserWithEmailAndPassword(email, pass).addOnSuccessListener(new OnSuccessListener<AuthResult>() {&nbsp; &nbsp; &nbsp; &nbsp; @Override&nbsp; &nbsp; &nbsp; &nbsp; public void onSuccess(AuthResult authResult) {&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;//done&nbsp; &nbsp; &nbsp; &nbsp; }&nbsp; &nbsp; }).addOnFailureListener(new OnFailureListener() {&nbsp; &nbsp; &nbsp; &nbsp; @Override&nbsp; &nbsp; &nbsp; &nbsp; public void onFailure(@NonNull Exception e) {&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; //display toast if registering failed&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; ToastRect.failed(RegisterActivity.this, getString(R.string.app_activities_error_text)&nbsp;&nbsp; &nbsp; &nbsp; &nbsp; }&nbsp; &nbsp;});

public class Register extends AppCompatActivity {private EditText mEmailField;private EditText mPasswordField;private EditText mConfirmPassword;private Button mRegisterButton;private FirebaseAuth mAuth;private FirebaseAuth.AuthStateListener mAuthListener;@Overrideprotected void onCreate(Bundle savedInstanceState) {&nbsp;

&nbsp; }&nbsp; &nbsp; &nbsp; &nbsp; });&nbsp; &nbsp; }}}为了确认火垒身份验证状态列表（）正在启动。这是来自我的登录类的糟糕的复制和粘贴作业。这阻止了我处理成功的用户创建。然后修复程序如下所示：public class Register extends AppCompatActivity {private EditText mEmailField;private EditText mPasswordField;private EditText mConfirmPassword;private Button mRegisterButton;private FirebaseAuth mAuth;private FirebaseAuth.AuthStateListener mAuthListener;@Overrideprotected void onCreate(Bundle savedInstanceState) {&nbsp;
