java - Firebase createUserWithEmailAndPassword task.isSuccessful()

Question

我正在创建一个 Android 应用程序并正在实现登录/注册功能。

我正处于注册 Activity 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();
            }
        });
    }
}

if !task.isSuccessful() 或 else block 都会到达，但用户是在 Firebase 中创建的。为什么我无法跟踪成功/失败的任何想法？

比较:

这在我的登录类中有效。

        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();
                }
            }
        });

很难说当前的实现方式如何。尝试直接添加一个 onSuccess

mAuth.createUserWithEmailAndPassword(email, pass).addOnSuccessListener(new OnSuccessListener<AuthResult>() {
        @Override
        public void onSuccess(AuthResult authResult) {
           //done
        }
    }).addOnFailureListener(new OnFailureListener() {
        @Override
        public void onFailure(@NonNull Exception e) {
            //display toast if registering failed
            ToastRect.failed(RegisterActivity.this, getString(R.string.app_activities_error_text) 
        }
   });
