Android Ilhasoft+；在数据绑定验证程序中出错；科特林

我试图将Android库与Kotlin一起使用，但我遇到了以下错误：未解析引用：验证

有人能帮我吗。

谢谢

validate

是库示例中按钮的id

您应该使用要验证的按钮的id。我认为这是新用户按钮

因此，对于绑定，它应该类似于

newUserButton

因此，您的完整示例如下所示：

override fun onCreateView(inflater: LayoutInflater, container: ViewGroup?, savedInstanceState: Bundle?): View? {

    val view = inflater.inflate(R.layout.fragment_cadastrar_user, null)

    //Binding Api
    val binding: FragmentCadastrarUserBinding = DataBindingUtil.setContentView(activity as Activity, R.layout.fragment_cadastrar_user)
    val  validator =  Validator(binding);

    // CHANGE IN BELOW LINE
    binding.newUserButton.setOnClickListener(View.OnClickListener {
        if (validator.validate()) {
            registerUser()
        }
    })

    binding.setUser(user);

    view.user_phone.addTextChangedListener(PhoneNumberFormattingTextWatcher())

    return view
}
