DialogFragment

class AlertDialogFragment : DialogFragment() {//상속 받을 때 주의

override fun onViewCreated(view: View, savedInstanceState: Bundle?) {
        super.onViewCreated(view, savedInstanceState)

        //5초뒤
        _binding?.btnAlertDialog1?.setOnClickListener {
            selectedAlarm = 1
        }
        //하루 전
        _binding?.btnAlertDialog2?.setOnClickListener {
            selectedAlarm = 2
        }
        //당일
        _binding?.btnAlertDialog3?.setOnClickListener {
            selectedAlarm = 3
        }
        //완료
        _binding?.alertBtnDialogComplete?.setOnClickListener {
            exit()
        }
        //취소
        _binding?.alertBtnDialogBack?.setOnClickListener {
            selectedAlarm = 0
            exit()
        }
    }

    //디테일페이지로 돌아가는 함수
    private fun exit() {
        val dialogResult =
            ContactDetailFragment.newInstance(friend!!, selectedAlarm)
        requireActivity().supportFragmentManager.beginTransaction()
            .replace(R.id.frame_layout, dialogResult).addToBackStack(null).commit()
        dismiss()
    }

MaterialAlertDialogBuider()

private fun requireAlarmPermission() {
        MaterialAlertDialogBuilder(
            requireContext(), R.style.detail_dialog_alert
        )
            .setTitle(getString(R.string.alarm_ask_permission))
            .setNegativeButton(getString(R.string.move)) { dialog, which ->
                val intent = Intent(Settings.ACTION_APP_NOTIFICATION_SETTINGS).apply {
                    putExtra(Settings.EXTRA_APP_PACKAGE, requireContext().packageName)
                }
                startActivity(intent)
            }
            .setPositiveButton(getString(R.string.cancel)) { dialog, which ->
                Toast.makeText(
                    requireContext(),
                    getString(R.string.alarm_need_permission),
                    Toast.LENGTH_LONG
                ).show()
            }
            .show()
        isNotCheck()
    }
