购物车圈子，adapter-优快云博客

本文链接：https://blog.youkuaiyun.com/Jang_AnGe/article/details/90743987

这篇博客探讨了购物车圈子的实现，重点关注了一个名为Fragment2的Fragment类，它实现了ConteatInterface.Fragment2Interface接口，并包含了QuanAdpater的使用。在Fragment中，初始化了一个包含QuanBean.ResultBean对象的列表，以及一个页面计数器。同时，博客还介绍了QuanAdpater，这是RecyclerView的适配器，用于展示QuanBean.ResultBean数据。
