简介： RecyclerView是support-v7包中的新组件，是一个强大的滑动组件，与经典的ListView相比，同样拥有item回收复用的功能，但是直接把viewholder的实现封装起来，用户只要实现自己的viewholder就可以了，该组件会自动帮你回收复用每一个item。 它不但变得更精简，也变得更加容易使用，而且更容易组合设计出自己需要的滑动布局。 要使用RecyclerView，其实你也可以只下载一个jar包，添加到自己的libs里就能使用它了 使用它的理由： RecyclerView is a more advanced and flexible version of ListView . This widget is a container for large sets of views that can be recycled and scrolled very efficiently. Use the RecyclerView widget when you have lists with elements that change dynamically. 简单说，它是ListView的进化，为了当你需要动态展示一组数据的时候就会需要它。 当然，如果只是动态展示数据，listview也可以做到，用它替代listview的原因有几个：

So far, I have tried getting the View at the first visible position of the RecyclerView , but that is always null . It's getChildCount() keeps returning 0 , and findViewHolderForPosition is always null . The adapter returns a non-0 number from getItemCount() (there are definitely items in the adapter). I'm using Robolectric 2.4 SNAPSHOT. 回答1: Seems like the issue was that RecyclerView needs to be measured and layed out manually in Robolectric. Calling this solves
