有同学希望能加上下拉刷新，上拉加载，其实也是简单的。我们还是用SwipeRefreshLayout吧。但我们现在面临一个问题，这个SwipeRefreshLayout加在哪？我见过案例是把SwipeRefreshLayout做为顶级View包在CoordinatorLayout的外面，我觉得这个做法还是很糟糕的，首先CoordinatorLayout推荐做为顶级View使用，现在又在外面套了个刷新，不伦不类的；其次，如上面的案例就会出现一个SwipeRefreshLayout会对应三个子列表的刷新，处理起来还是麻烦。我们是不是可以把SwipeRefreshLayout套在ViewPager外面呢？也是可以的，但还是麻烦。我们就把下拉刷新这件事交给Fragment自己来做好了。
