RecyclerView ni kipengele cha kawaida cha Android cha kuonyesha orodha zinazosogezeka za data kwa ufanisi. "Hutumia tena" views (kuzitumia upya unaposogeza) badala ya kuunda view kwa kila kipengele — ni muhimu kwa utendaji kwenye orodha ndefu.
Kwa nini RecyclerView (dhana ya kutumia tena)
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.
