本文介绍了如何在WEEX-EEUI项目中，通过引入新的依赖并创建自定义的scrollview实现类SWRecyler，用SmartRefreshLayout替代原生的SwipeRefreshLayout。教程包括修改build.gradle文件添加配置、复制并重命名Recycler为SWRecyler，以及调整组件注册位置。这种方法虽非最佳实践，但能有效达成目标。欢迎点赞和关注以支持作者。

引入依赖

去eeui库目录下的build.gradle文件中添加下面配置如图

implementation 'com.scwang.smartrefresh:SmartRefreshLayout:1.1.2'

这里为了方便起见，直接复制Recycler,重命名SWRecyler
