求大神相助，仿MIUI、微信来电通知无法解决通知折叠到通知列表

求相助，希望有大神帮我解决下，我想做一个类似小米来电的通知功能，我发现小米的来电通知不会自动折叠到通知列表，而我无论如何设置，我的通知都会折叠通知列表里，求助解决方案

如图：来电通知并不会折叠到下拉通知列表

我的通知部分代码：

    public static void buildCallNotification(Service service, final PendingIntent resultPendingIntent) {
        Log.d(TAG,"buildCallNotification");
        NotificationCompat.Builder builder;
        if (android.os.Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
            builder = new NotificationCompat.Builder(service, NotificationChannelsUtils.CALL_CHANNEL);
        } else {
            builder = new NotificationCompat.Builder(service);
        }
        builder.setSmallIcon(getSmallIconResId())
                .setContentTitle(service.getResources().getText(R.string.channel_call))
                .setCategory(NotificationCompat.CATEGORY_CALL)
                .setContentIntent(resultPendingIntent)
                .setTicker(service.getResources().getText(R.string.channel_call))
                .setFullScreenIntent(resultPendingIntent,true)
                .setPriority(NotificationCompat.PRIORITY_MAX)
                .setOngoing(true);

        Notification notification = builder.build();
        service.startForeground(NOTIFICATION_ID_INCOMINGCALL, notification);
    }

渠道部分代码：

    @RequiresApi(api = Build.VERSION_CODES.O)
    private static NotificationChannel getCallChannel(Context context){
        NotificationChannel notificationChannel = new NotificationChannel(CALL_CHANNEL, context.getString(R.string.channel_call), NotificationManager.IMPORTANCE_HIGH);
        notificationChannel.setLockscreenVisibility(Notification.VISIBILITY_PUBLIC);
        notificationChannel.setSound(null, null);
        notificationChannel.setImportance(NotificationManager.IMPORTANCE_HIGH);
        return notificationChannel;
    }
