RecyclerView Pulltorefresh and loadmore it still has some problems ,when your recyclerview LayoutManager is StaggeredGridLayoutManager then you pull to refresh the data you will get empty view 这个项目还有问题,当你把recyclerview的LayoutManager设置成StaggeredGridLayoutManager的时候,下拉刷新会得到空白的view 填充在最上面(解决办法是不再回调中再次设置adapter,直接notify的话就不会有问题)。这个应该是StaggeredGridLayoutManager的 一个小bug
