当我试着打电话的时候 dismiss() 在我的messageboxbuilder上，但我 Unresolved reference: dismiss ，我尝试在messageboxview上调用它并更改它 setCancelable() 至 true 但同样的事情发生了。

fun create_Alert_Dialog(){
    //Alert dialog builder
    val messageBoxView = LayoutInflater.from(this).inflate(R.layout.layout_dialog,null)
    //Alert dialog builder
    val messageBoxBuilder = AlertDialog.Builder(this).setView(messageBoxView)
    //Setting undissmissable
    messageBoxBuilder.setCancelable(false)
    //Show
    messageBoxBuilder.create().show()
    bt4 = messageBoxView.findViewById(R.id.bt4)
    bt4.setOnClickListener {
        Lose()
        messageBoxBuilder.dismiss()
    }
}
