一手遮天 Android - view(RecyclerView): RecyclerView 下拉刷新(结合 SwipeRefreshLayout 控件实现)
示例如下:
/view/recyclerview/RecyclerViewDemo3.java
/**
* 演示 RecyclerView 的下拉刷新,结合 SwipeRefreshLayout 控件实现
*
*
* 引入 SwipeRefreshLayout 控件的话,需要在 app 的 build.gradle 中配置好 implementation "androidx.swiperefreshlayout:swiperefreshlayout:x.x.x"
