Research direction
Examine how individual layout helpers handle background drawing by looking at the LayoutHelper base class and related drawing code. The issue requests a way to apply a single background across multiple helpers, which may require modifying the RecyclerView's canvas or introducing a new layout helper. Check the assigned developer's activity and any comments on the issue for additional context.
