RecyclerView SnapHelper fails to show first/last items

Question

I have a RecyclerView which is attached to a LinearSnapHelper to snap to center item. When I scroll to the first or last items, these items are not ful

Answer 1

I tried to implement a simple solution. Basically I checked if the first/last items are completely visible. If so, we don't need to perform the snap. See the solution below:

class CarouselSnapHelper : LinearSnapHelper() {

    override fun findSnapView(layoutManager: RecyclerView.LayoutManager): View? {
        val linearLayoutManager = layoutManager as? LinearLayoutManager
            ?: return super.findSnapView(layoutManager)

        return linearLayoutManager
            .takeIf { isValidSnap(it) }
            ?.run { super.findSnapView(layoutManager) }
    }

    private fun isValidSnap(linearLayoutManager: LinearLayoutManager) =
        linearLayoutManager.findFirstCompletelyVisibleItemPosition() != 0 &&
            linearLayoutManager.findLastCompletelyVisibleItemPosition() != linearLayoutManager.itemCount - 1
}
