1.解决
先调用((SimpleItemAnimator)imagesListView.getItemAnimator()).setSupportsChangeAnimations(false); //取消RecyclerView的动画果
fragmentLeftFloorAdapter2.notifyItemRangeChanged(0,fragmentLeftFloorAdapter2.getItemCount());
2.（没有测试）
手动创建给RecyclerViewPool对象，指定它的大小，再传给RecyclerView对象。
RecyclerView.RecycledViewPool pool= new RecyclerView.RecycledViewPool();
pool.setMaxRecycledViews(0, 10);
recyclerView.setRecycledViewPool(pool);
