Question

我有一个接收通知的应用程序，一切正常。但是，自定义声音和振动不起作用。我正在Android 9 Pie上对其进行测试。

Uri sound = Uri.parse("android.resource://" +getApplicationContext().getPackageName()+ "/" +R.raw.siren); //ContentResolver.SCHEME_ANDROID_RESOURCE +

    String NOTIFICATION_CHANNEL_ID = "com.example.bantay.bantay.test";
    NotificationManager notificationManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);

    NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(this, NOTIFICATION_CHANNEL_ID);

    notificationBuilder.setAutoCancel(true);
    notificationBuilder.setWhen(System.currentTimeMillis());
    notificationBuilder.setSmallIcon(R.drawable.marikinalogo);
    notificationBuilder.setContentTitle(title);
    notificationBuilder.setContentText(body);
    notificationBuilder.setSound(sound);
    notificationBuilder.setVibrate(new long[]{500, 1000, 500, 1000});
    if(title.toLowerCase().contains("1")){
        notificationBuilder.setContentIntent(pendingIntent);
    }
    else{
        notificationBuilder.setContentIntent(pendingIntent3);
    }

    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
        NotificationChannel notificationChannel = new NotificationChannel(NOTIFICATION_CHANNEL_ID, "Notification", NotificationManager.IMPORTANCE_HIGH);

        AudioAttributes audioAttributes = new AudioAttributes.Builder()
                .setContentType(AudioAttributes.CONTENT_TYPE_SONIFICATION)
                .setUsage(AudioAttributes.USAGE_ALARM)
                .build();

        notificationChannel.enableLights(true);
        notificationChannel.setLightColor(Color.RED);
        notificationChannel.enableVibration(true);
        notificationChannel.setVibrationPattern(new long[]{500, 1000, 500, 1000});
        notificationChannel.setSound(sound, audioAttributes);
        notificationManager.createNotificationChannel(notificationChannel);
    }

    notificationManager.notify(0, notificationBuilder.build());

我不知道我的错误。 NOTIFICATION_CHANNEL_ID是否会影响通知的行为？

我正在使用MediaPlayer自定义声音。这对我来说很好。这适用于所有设备。

private MediaPlayer player;

要播放自定义声音：

 try {
       Uri uri = Uri.parse("android.resource://" + getPackageName() + "/" + R.raw.siren);

       player = MediaPlayer.create(this, uri);
       player.setLooping(true); // This will play sound in repeatable mode.
       player.start();

//     mBuilder.setSound(uri);
     } catch (Exception e) {
        e.printStackTrace();
    }

停止声音：

  if (player != null)
      player.stop();

这对我有用。希望这对您有帮助。
