上拉加载使用的是单独的viewtype方式做的，现在基于recyclerview的上拉加载都是基于这种方式实现的，我的印象中是rv是按照viewtype来复用的，但是上拉加载是一个单独的viewtype，所以不存在复用的情况。

你可以放心的，这种方式基本不用考虑内存的开销。

我的意思是他上拉加载后生成的每一个itemView好像都是一个全新的对象，这个是不是就有点奇怪了，我用的是你的demo中 StickyRvCoordinatorActivity，每个itemView里面都有一个mediaplayer，然后每次都生成一个新的对象，快速滑动的时候mediaplayer播放会出错

我觉得 你不加加载更多的功能，就用原生的RV，也是这样的情况。

这个和列表里加"倒计时功能"同理，我觉得你应该新建一个HashMap用来存储mediaplayer，存 position和mediaplayer，如果position没有就新建一个mediaplayer然后存起来；有position就直接取mediaplayer使用，然后再离开页面的时候销毁HashMap，你也可以限制HashMap的大小保障内存开销。

而且我觉得你应该还要记录item播放视频对应的进度，等再次滑到那个item时直接定位到那个进度
