我在项目https://github.com/IslamKhSh/CardSlider中使用此库 我需要在两个方向上实现无限滚动。 我试图从stackoverflow中找到一些实现，但是没有一个对我有帮助。
我在两个冻结的应用程序中都尝试了两种解决方案。

也许您知道一些替代库？

我这样实现了此功能。
val items = ArrayList<Level>()
override fun getItemCount(): Int = if (items.isEmpty()) 0 else Integer.MAX_VALUE
override fun onBindViewHolder(holder: CategoryViewHolder, position: Int) {
holder.bind(items[position % items.size])
}
