ListView - Recycle Your Knowledge
summary
Covers Android list rendering: starts from naive view inflation and shows the ViewHolder pattern to avoid repeated findViewById calls and restore smooth scrolling (~60fps). Then explains RecyclerView features—layout managers, item decorators, and DiffUtil for animated list updates—and finally shows Jetpack Compose LazyColumn with compose identity/keys and coroutine-based scroll state; example code is provided and runnable.
