我正在尝试向Firebase和Kotlin进行注册。 看一下docs,我看到了Java中的所有例子。因此,当我尝试在Kotlin中实施时,我无法使其发挥作用。

在Java中应该是这样的:

// [START create_user_with_email]
        mAuth.createUserWithEmailAndPassword(email, password)
                .addOnCompleteListener(this, new OnCompleteListener<AuthResult>() {
                    @Override
                    public void onComplete(@NonNull Task<AuthResult> task) {
                        if (task.isSuccessful()) {
                            // Sign in success, update UI with the signed-in user's information
                            FirebaseUser user = mAuth.getCurrentUser();

                        } else {
                            // If sign in fails, display a message to the user.
                            ......
                        }

                        // [START_EXCLUDE]
                        .......
                        // [END_EXCLUDE]
                    }
                });
        // [END create_user_with_email]

但是当我尝试在kotlin中实现这样的时候:

// [START create_user_with_email]
        mAuth.createUserWithEmailAndPassword(email, password)
                .addOnCompleteListener(this, OnCompleteListener<AuthResult> { task ->
                    if (task.isSuccessful) {
                        // Sign in success, update UI with the signed-in user's information                        
                        val user = mAuth.currentUser                       
                    } else {
                        ......
                    }

                    // [START_EXCLUDE]
                            .....
                    // [END_EXCLUDE]
                })
        // [END create_user_with_email]

但是这个,给我一个错误: enter image description here

而且我不知道如何解决它。

我已通过以下方式使用电子邮件和密码实施Firebase注册,并且可以正常运行:

this.firebaseAuth.createUserWithEmailAndPassword(email, password).addOnCompleteListener { task: Task<AuthResult> ->
    if (task.isSuccessful) {
        //Registration OK
        val firebaseUser = this.firebaseAuth.currentUser!!
    } else {
        //Registration error 
    }
}

auth.createUserWithEmailAndPassword(email,pass).addOnCompleteListener(object: OnCompleteListener<AuthResult>{
                        override fun onComplete(p0: Task<AuthResult>) {
                            TODO("not implemented") //To change body of created functions use File | Settings | File Templates.
                        }
                    })
