Android通知 - setSound不起作用

我已经查看过有关此主题的几个问题,并且似乎都建议在通知构建器中简单地使用.setSound(alarmSound)会导致手机播放通知声音。但是,我这样做并且它无法正常工作。

我可能错过了一些东西,但我无法找到它。

以下是我用来发出通知的代码:

private void newArrivalNotification(String locId, String userId) {

    ...

    mNotificationManager = (NotificationManager)
            this.getSystemService(Context.NOTIFICATION_SERVICE);

    Intent mainActivity = new Intent(this, MainActivity.class);

    PendingIntent contentIntent = PendingIntent.getActivity(this, locId.hashCode(),
            mainActivity, 0);

    Uri alarmSound = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);

    if(alarmSound == null) {
        Log.w("GcmIntentService", "alarmSound is null");
    }

    NotificationCompat.Builder mBuilder =
            new NotificationCompat.Builder(this)
                .setAutoCancel(true)
                .setSmallIcon(R.drawable.ic_launcher)
                .setContentTitle(title)
                .setStyle(new NotificationCompat.BigTextStyle()
                    .bigText(msg))
                .setSound(alarmSound, AudioManager.STREAM_NOTIFICATION)
                .setTicker(msg)
                .setContentText(msg);

    mBuilder.setContentIntent(contentIntent);

    Notification arrivalNotification = mBuilder.build();
    arrivalNotification.defaults |= Notification.DEFAULT_VIBRATE;

    mNotificationManager.notify(NOTIFICATION_ID, arrivalNotification);
}

你能发现我做错的事吗?我找了几个小时,却找不到任何东西。

问题是您正在使用这行代码修改默认通知行为(声音和振动)。

Notification arrivalNotification = mBuilder.build();
arrivalNotification.defaults |= Notification.DEFAULT_VIBRATE;
mNotificationManager.notify(NOTIFICATION_ID, arrivalNotification);

您可以使用以下方法再次激活它:

int defaults = 0;
defaults |= Notification.DEFAULT_SOUND;
defaults |= Notification.DEFAULT_VIBRATE;
mBuilder.setDefaults(defaults);
mNotificationManager.notify(NOTIFICATION_ID, mBuilder.build());

我希望这对你有所帮助! ;)
