Her zaman fromPosition<\/code> ve toPosition<\/code> parametrelerinin do\u011fru oldu\u011fundan ve Collections.swap<\/code> gibi metodlarla veri listesinin de g\u00fcncellendi\u011finden emin olun.
\n*   \u0130\u00e7 \u0130\u00e7e RecyclerView’lar:<\/strong> Bir RecyclerView i\u00e7inde ba\u015fka bir RecyclerView varsa, dokunma olaylar\u0131 \u00e7ak\u0131\u015fabilir.

G\u00f6rsel geri bildirimler i\u00e7in sadece View \u00f6zelliklerini (arka plan rengi, y\u00fckselme) de\u011fi\u015ftirmek genellikle yeterlidir. notifyDataSetChanged()<\/code> yerine notifyItemMoved()<\/code> kullanmak da performans\u0131 art\u0131r\u0131r.
\n*   G\u00f6rsel Hatalar (Flickering, Overlapping):<\/strong> Bazen s\u00fcr\u00fckleme s\u0131ras\u0131nda \u00f6\u011felerin titremesi veya \u00fcst \u00fcste binmesi gibi g\u00f6rsel hatalar olu\u015fabilir. Bu genellikle onMove<\/code> veya onSelectedChanged<\/code> metodlar\u0131nda yap\u0131lan yanl\u0131\u015f UI g\u00fcncellemelerinden kaynaklan\u0131r. clearView<\/code> metodunda t\u00fcm g\u00f6rsel de\u011fi\u015fikliklerin s\u0131f\u0131rland\u0131\u011f\u0131ndan emin olun.
