_x000D_ First / last visible child depends on the LayoutManager. If you are using LinearLayoutManager or GridLayoutManager, you can use int findFirstVisibleItemPosition(); int findFirstCompletelyVisibleItemPosition(); int findLastVisibleItemPosition(); int findLastCompletelyVisibleItemPosition(); For example: GridLayoutManager layoutManager = ((GridLayoutManager)mRecyclerView.getLayoutManager()); int firstVisiblePosition = layoutManager.findFirstVisibleItemPosition(); For LinearLayoutManager, first/last depends on the adapter ordering. Don't query children from RecyclerView; LayoutManager may prefer to layout more items than visible for caching.
