Question

我已经创建了一个闹钟应用作为我的第一个 kotlin 个人项目，但我在使用“请勿打扰”模式时遇到了问题。我创建闹钟的方式是：

使用日期选择器选择闹钟时间/日期。

使用挂起的 Intent 和 AlarmManager 来安排警报，如您在代码中所见。

//2. Get AlarmManager instance
alarmManager = getSystemService(ALARM_SERVICE) as AlarmManager
//3. Pending Intent
val pendingIntentRequestCode = 10  //Para recuperar el intent
val flag = 0
pendingIntentAlarm = PendingIntent.getBroadcast(this, pendingIntentRequestCode, intent, flag)
// 4. Schedule the alarm
alarmManager!!.setExactAndAllowWhileIdle(AlarmManager.RTC_WAKEUP, schedule.timeInMillis, pendingIntentAlarm)

要接收待处理的意图，请运行我使用 BroadcastReceiver 的警报操作：

class AlarmReceiver: BroadcastReceiver() {
@RequiresApi(Build.VERSION_CODES.O)
override fun onReceive(context: Context, intent: Intent) {

我过去打开闹钟的方式是发出通知。为了在 android 中创建和运行通知，我为 android Oreo 及更高版本创建了通知通道。代码是：

通知渠道创建：

val CHANNEL_ID = "runAlarm"
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
        val name = getString(R.string.channel_runal_name)
        val descriptionText = getString(R.string.channel_runal_desc)
        val importance = NotificationManager.IMPORTANCE_HIGH
        val channel = NotificationChannel(CHANNEL_ID, name, importance).apply {
            description = descriptionText
        }
        val audioAttributes = AudioAttributes.Builder()
                .setContentType(AudioAttributes.CONTENT_TYPE_MUSIC)
                .setLegacyStreamType(AudioManager.STREAM_ALARM)
                .setUsage(AudioAttributes.USAGE_ALARM)
                .setFlags(AudioAttributes.FLAG_AUDIBILITY_ENFORCED)
                .build()

        channel.setSound(RingtoneManager.getDefaultUri(RingtoneManager.TYPE_ALARM), audioAttributes)
        channel.enableLights(true)
        channel.enableVibration(true)
        channel.lockscreenVisibility = NotificationCompat.VISIBILITY_PUBLIC
        channel.setBypassDnd(true)
        // Register the channel with the system
        notificationManager = (getSystemService(Context.NOTIFICATION_SERVICE) as NotificationManager)
        notificationManager!!.createNotificationChannel(channel)

通知构建和启动：

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
        val notification = Notification.Builder(context, "runAlarm")
                .setSmallIcon(R.drawable.alarm_icon) 
                .setContentTitle("GET UP!!!")          
                .setCategory(Notification.CATEGORY_ALARM)
                .setOngoing(true) 
                .setFullScreenIntent(fullScreenPendingIntent, true)
                .setOnlyAlertOnce(true)                    
                .build()

        //Launch notification
        val notifId = 2
        val notificationManager = context.getSystemService(Context.NOTIFICATION_SERVICE) as NotificationManager
        notificationManager.cancel(schedNotifId)
        notificationManager.notify(notifId, notification)           

    } else { //NO SUENA PARA SISTEMAS MENORES O IGUALES QUE OREO_MR1 EN MODO DO NOT DISTURB
        val notification = NotificationCompat.Builder(context, "runAlarm")
                .setSmallIcon(R.drawable.alarm_icon)
                .setContentTitle("GET UP!!!")  
                .setPriority(NotificationCompat.PRIORITY_MAX)
                .setCategory(NotificationCompat.CATEGORY_ALARM)
                .setVisibility(NotificationCompat.VISIBILITY_PUBLIC)
                .setOngoing(true)
                .setFullScreenIntent(fullScreenPendingIntent, true)
                .setSound(RingtoneManager.getDefaultUri(RingtoneManager.TYPE_ALARM), AudioManager.STREAM_ALARM)
                .setOnlyAlertOnce(true)
                .setDefaults(Notification.DEFAULT_SOUND or NotificationCompat.DEFAULT_VIBRATE)
                .build()

        //Launch notification
        val notifId = 2
        val notificationManager = NotificationManagerCompat.from(context)
        notification.flags = NotificationCompat.FLAG_INSISTENT
        notificationManager.cancel(schedNotifId)
        notificationManager.notify(notifId, notification)

但是，使用此配置，通知会出现，但不会在正常模式和免打扰 (DnD) 模式下响铃。

为了尝试修复它，我在通知调用后添加了声音服务。调用服务的代码是：

val startIntent = Intent(context, RingtonePlayingService::class.java)
context.startService(startIntent)

服务描述如下：

class RingtonePlayingService : Service() {
private var ringtone: Ringtone? = null
override fun onBind(intent: Intent): IBinder? {
    return null
}

override fun onStartCommand(intent: Intent, flags: Int, startId: Int): Int {
    val ringtoneUri = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_ALARM)
    ringtone = RingtoneManager.getRingtone(this, ringtoneUri)

    ringtone!!.play()
    return START_NOT_STICKY
}

override fun onDestroy() {
    ringtone!!.stop()
}

现在，Android Oreo 及更高版本的闹钟在正常和 DnD 模式下响起，在 android < Oreo 中在正常模式下响起，但其音量取决于铃声音量而不是闹钟音量。

但是在 DnD 模式下它不会在 android < Oreo 中发声，并且音量还取决于铃声音量而不是闹钟音量。

我不知道问题是否是因为这是最好的方法，任何帮助将不胜感激。

先谢谢你！
