        val builder = AlertDialog.Builder(this)
        builder.setTitle("주의!")
            .setMessage("메시지")
            .setPositiveButton("확인",DialogInterface.OnClickListener { dialogInterface, i ->  Positive_Button()})
            .setNegativeButton("취소", DialogInterface.OnClickListener { dialogInterface, i -> Negative_Button() })
        builder.show()
    }

2. List AlertDialog

    binding.button2.setOnClickListener {
        val Items : Array<String> = arrayOf("사과","포도","복숭아","키위","바나나")
        val builder = AlertDialog.Builder(this)
            .setTitle("과일 선택")
            .setItems(Items, DialogInterface.OnClickListener { dialogInterface, i ->
                Choice(Items[i])
            })
        builder.show()
