Check if RecyclerView is scrollable

Question

How to check if a RecyclerView is scrollable, ie, there are items below/above the visible area

I have a dropdown in my recycler view which works by using

Answer 1

What about

// 1 = down; -1 = up
recyclerView.canScrollVertically(-1)

If you want to check if there is any scrollable space, no matter which direction

cardList.canScrollVertically(1) || cardList.canScrollVertically(-1)
