This article explains ArkUI's component lifecycle hooks, the low‑level FrameNode API, LazyForEach rendering strategy with key generation, the full rendering pipeline, custom measure/layout methods, event bubbling, differences between property and explicit animations, and the purpose of XComponent for native rendering.
This article explains HarmonyOS long‑list rendering techniques, comparing the one‑time ForEach approach with the on‑demand LazyForEach method, and detailing cacheCount and @Reusable component reuse strategies, migration challenges from iOS/Android, ArkTS and C‑API implementations, and performance test results.
This article examines the challenges of rendering long lists on HarmonyOS across iOS, Android, and Web platforms, explains the ForEach and LazyForEach mechanisms, and presents practical ArkTS and C++ solutions—including cacheCount, component reuse, and performance optimizations—to achieve smoother UI and lower memory usage.
This article explains HarmonyOS long‑list rendering challenges and presents practical ArkTS and C++ solutions—including LazyForEach, CacheCount, and @Reusable component reuse—to dramatically improve performance, reduce memory usage, and eliminate frame drops across iOS, Android, and HarmonyOS platforms.
