我正在使用Recycler View来显示共享首选项ID中的项目。我必须删除Recyler View项目以及SharedPreference商店项目。 但是当我试图删除Recycler View的项目时，我收到了错误。

如何解决这个问题我使用两个模型作为一个适配器可能是因为我收到这样的错误。 在此先感谢。
答案 0 :(得分：1)
在调用getAdapterPosition()
getPosition而不是removeAt
答案 1 :(得分：0)
在你的getItem（int position）上，你将返回你的cartlistadp2（arraylist2）。
我不知道下面的代码在getItemCount（）中实际执行了什么，但也将此代码用于getItem（）
if (cartlistadp.equals(cartlistadp)) {
return cartlistadp.get(position);
}
if (cartlistadp2.equals(cartlistadp2)) {
return cartlistadp2.get(position);
}
