小编dgn*_*can的帖子

RecyclerView有一个InfiniteScrollListener并且在该侦听器中,在OnScrolled()方法I中计算可见项和总项数以检查是否应该加载新项.当totalItemCount和visibleItemCount相同时,它会导致无限循环加载.听众与我RecyclerView没有CoordinatorLayout或NestedScrollView作为父母的其他人完美无瑕地工作.我想保留这种结构,因为客户不会接受更改.

我在活动中有一个像这样的布局的片段

CoordinatorLayout{
 NestedScrollView{
    RecyclerView{
    }
 }
}
