I need to know which elements are currently displayed in my RecyclerView. There is no equivalent to the href=”http://developer.android.com/reference/android/widget/AbsListView.OnScrollListener.html#onScroll%28android.widget.AbsListView,%20int,%20int,%20int%29″>
OnScrollListener.onScroll(...) method on ListViews. I tried to work with
View.getGlobalVisibleRect(...), but that hack is too ugly and does not always work too.
Someone any ideas?
First / last visible child depends on the
LayoutManager. If you are using
GridLayoutManager, you can use
int findFirstVisibleItemPosition(); int findFirstCompletelyVisibleItemPosition(); int findLastVisibleItemPosition(); int findLastCompletelyVisibleItemPosition();
GridLayoutManager layoutManager = ((GridLayoutManager)mRecyclerView.getLayoutManager()); int firstVisiblePosition = layoutManager.findFirstVisibleItemPosition();
LinearLayoutManager, first/last depends on the adapter ordering. Don’t query children from
LayoutManager may prefer to layout more items than visible for caching.
