android - GCM 通知 setAutoCancel(true) 在 Android 5.1.1 中不起作用

Question

我正在使用此代码显示通知，但 setAutoCancel(true) 不起作用，因为当我按下通知以打开应用程序时，通知仍在通知栏上，我必须用手指手势手动删除它用于删除通知或使用通知栏中的全部清除按钮。

它在 android 4.4.2 设备上工作正常，但在我的 nexus 7 和 5.1.1 上不工作

怎么了？

private void generateNotification(Context context, String message) {

    Intent intent = new Intent(GCMListenerService.this, MainActivity.class);
    intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
    PendingIntent pendingIntent = PendingIntent.getActivity(context, 0, intent, PendingIntent.FLAG_ONE_SHOT);

    Bitmap image = BitmapFactory.decodeResource(getResources(), R.drawable.ic_launcher);
    String appName = context.getResources().getString(R.string.app_name);       

    int width;
    int height;
    if (Util.checkAndroidVersionUpperOrEqualThan(11)){      
        width = getResources().getDimensionPixelSize(android.R.dimen.notification_large_icon_width); 
        height = getResources().getDimensionPixelSize(android.R.dimen.notification_large_icon_height);
    }else{
        width = 64;
        height = 64;
    }

    image = Bitmap.createScaledBitmap(image, width, height, false);

    Uri defaultSoundUri = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
    NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(getApplicationContext())
    .setSmallIcon(R.drawable.ic_launcher)
    .setLargeIcon(image)
    .setContentTitle(appName)
    .setContentText(message)
    .setSound(defaultSoundUri)
    .setPriority(NotificationCompat.PRIORITY_HIGH)
    .setContentIntent(pendingIntent)
    .setAutoCancel(true)
    .setStyle(new NotificationCompat.BigTextStyle().bigText(message));

    NotificationManager notificationManager = (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);

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

}

您必须使用 .setOngoing(true) 设置通知标志

   val builder = NotificationCompat.Builder(context, channelId)
   builder.setOngoing(true)
   notification = builder.build()
   notification.flags = Notification.FLAG_ONGOING_EVENT
