RecyclerView is an Android component caighdeánach chun liostaí sonraí inscrolálaithe a thaispeáint go héifeachtúil. Déanann sé "athchúrsáil" ar dhéanann sé (á n-athúsáid agus a bhíonn tú ag scrolláil) seachas amharc a dhéanamh do gach mír — ríthábhachtach do dheis le liostaí fada.
Cén fáth RecyclerView (an coincheap athchúrsála)
Displaying a long list naively (a view per item) is WASTEFUL — thousands of items =
thousands of views = memory/performance problems.
RECYCLERVIEW reuses a small pool of views:
→ only views for VISIBLE items exist; as you scroll, off-screen views are RECYCLED
(re-bound with new data) for newly-visible items
→ constant memory regardless of list size → smooth, efficient scrolling
→ This recycling is the key to performant lists.
