阻止扩展通知视图

Question

我有这段代码来设置我的通知样式：

    remoteViews = new RemoteViews(context.getPackageName(), R.layout.notification);

    mBuilder = new NotificationCompat.Builder(context);
    mBuilder.setSmallIcon(R.drawable.ic_stat_notification);
    mBuilder.setCustomContentView(remoteViews);
    mBuilder.setOngoing(true);
    mBuilder.setCategory(NotificationCompat.CATEGORY_PROGRESS);
    mBuilder.setPriority(NotificationCompat.PRIORITY_HIGH);
    mBuilder.setShowWhen(false);
    mBuilder.setStyle(new NotificationCompat.DecoratedCustomViewStyle());
    mBuilder.setAutoCancel(true);

如您所见，我没有通过调用mBuilder.setCustomBigContentView() 为通知定义扩展视图。然而，通知显示为向上箭头，就好像我的通知已展开一样。如何防止该箭头显示？

mBuilder.setStyle(new NotificationCompat.DecoratedCustomViewStyle());
