NotificationManager.cancel（id）不起作用

Question

这是我的发送通知方法，但问题是我收到通知但无法取消它。我希望我的通知在15分钟后被删除，并且在通知后由用户点击后也会被删除。

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

    contentIntent = PendingIntent.getActivity(
      this, 
      0, 
      intent, 
      0); 

    NotificationCompat.Builder alamNotificationBuilder = new NotificationCompat.Builder(
      this).setContentTitle("Recite Dua").setSmallIcon(R.mipmap.ic_launcher) 
      .setStyle(new NotificationCompat.BigTextStyle().bigText(msg)) 
      .setContentText(msg); 

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

    long[] pattern = {500, 500, 500, 500, 500, 500, 500, 500, 500}; 
    alamNotificationBuilder.setVibrate(pattern); 

    alamNotificationBuilder.setContentIntent(contentIntent); 
    alarmNotificationManager.notify(1, alamNotificationBuilder.build()); 
    Log.d("AlarmService", "Notification sent."); 

    removeNotification(); 
} 

private void removeNotification() { 

     Handler handler = new Handler(); 
     long delayInMilliseconds = 1000; 
     handler.postDelayed(new Runnable() { 
      public void run() { 
       stopForeground(false); 
       alarmNotificationManager.cancel(1); 
      } 
     }, delayInMilliseconds); 
}

使用stopForeground(true); 它清除该ID在startForeground方法使用的通知。
