Dynamic lists like RecyclerView in Android show data efficiently by reusing views. This reuse keeps the frame rate smooth, aiming for 60fps. It reduces memory use because it only creates views for visible items, not the whole list. This also saves battery since less work is done when scrolling.
To keep scrolling smooth, use view recycling properly. Avoid creating new views unnecessarily. Use DiffUtil to update only changed items instead of refreshing the whole list. Load images asynchronously and cache them to avoid blocking the UI thread. Keep item layouts simple and avoid heavy operations in binding.
Using dynamic lists adds minimal size because RecyclerView is part of Android Jetpack libraries. Custom adapters and layouts add small size depending on complexity. Startup time is mostly unaffected since views are created on demand during scrolling, not all at once.
Android uses RecyclerView for dynamic lists, which recycles views efficiently. iOS uses UITableView or UICollectionView with similar reuse patterns. Both platforms aim for smooth scrolling and low memory use. Implementation details differ, but the concept of view reuse is key on both.
Both Google Play and Apple App Store require apps to be responsive and not freeze during use. Efficient dynamic lists help meet these guidelines by preventing UI hangs. Avoid excessive memory use to prevent app crashes, which can cause rejection. Follow platform UI guidelines for list appearance and behavior.
Your app takes 5 seconds to load this screen. What's likely wrong? You might be creating all list item views at once instead of recycling. Or loading large images on the main thread blocking UI. Check if you update the whole list unnecessarily instead of using DiffUtil or similar.
