summary
Shows how RecyclerView’s ConcatAdapter (introduced as MergeAdapter in RecyclerView 1.2.0‑alpha) composes multiple adapters sequentially so each list stays encapsulated and reusable, with APIs to addAdapter(index, adapter) and removeAdapter(adapter), constructors taking adapter lists or configs, and a Config for isolateViewTypes and three stable ID modes (NO, ISOLATED, SHARED). getBindingAdapterPosition returns per‑adapter positions, notifyDataSetChanged broadcasts to all children, adapters cannot interleave (only sequential) and horizontal carousels work via nested RecyclerViews.
