[패스트캠퍼스 챌린지 20일차] Android alarm앱 마무리

class AlarmReceiver:BroadcastReceiver() {
    companion object{
        const val NOTIFICATION_ID = 100
        const val NOTIFICATION_CHANNEL_ID = "1000"
    }
    override fun onReceive(context: Context, intent: Intent?) {
        createNotificationChannel(context)
        notifyNotification(context)
    }

    private fun createNotificationChannel(context: Context) {
        if(Build.VERSION.SDK_INT >= Build.VERSION_CODES.O){
            val notificationChannel = NotificationChannel(
                NOTIFICATION_CHANNEL_ID,
                "기상 알람",
                NotificationManager.IMPORTANCE_HIGH
            )
            NotificationManagerCompat.from(context).createNotificationChannel(notificationChannel)
        }
    }

    private fun notifyNotification(context: Context){
        with(NotificationManagerCompat.from(context)){
            val build = NotificationCompat.Builder(context, NOTIFICATION_CHANNEL_ID)
                .setContentTitle("알람")
                .setContentText("일어날 시간입니다.")
                .setSmallIcon(R.drawable.ic_alarm)
                .setPriority(NotificationCompat.PRIORITY_HIGH)


            notify(NOTIFICATION_ID, build.build())

        }
    }
}

전달받은 알람이 휴대폰에 보여지기 위해서 notification channel을 생성하고 notify 해주는 기능을 담은 AlarmReceiver 클래스를 작성하였습니다.

private fun fetchDataFromSharedPreferences(): AlarmDisplayModel {
        val sharedPreferences = getSharedPreferences(SHARED_PREFERENCES_NAME, Context.MODE_PRIVATE)
        val timeDBValue = sharedPreferences.getString(ALARM_KEY, "9:30") ?: "9:30"
        val onOffDBValue = sharedPreferences.getBoolean(ON_OFF_KEY, false)
        val alarmData = timeDBValue.split(":")

        val alarmModel = AlarmDisplayModel(
            hour = alarmData[0].toInt(),
            minute = alarmData[1].toInt(),
            onOff = onOffDBValue
        )

        val pendingIntent = PendingIntent.getBroadcast(this, ALARM_REQUEST_CODE, Intent(this, AlarmReceiver::class.java), PendingIntent.FLAG_NO_CREATE)
        if((pendingIntent == null) and alarmModel.onOff){
            //알람은 꺼져있는데 데이터가 켜져있는 경우
            alarmModel.onOff = false

        }else if((pendingIntent != null) and alarmModel.onOff.not()){
            //알람은 켜져있는데 데이터가 꺼져있는경우
            //알람을 취소함
            pendingIntent.cancel()
        }
        return alarmModel
    }
