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;
}
