Episode notes
INSIGHT

Lazy Layout Focus

  • Compose's lazy layouts prioritize lazy creation over explicit reuse.
  • They offer similar performance to RecyclerView through automatic reuse and optimization.
INSIGHT

Layout Node Reuse

  • Compose lazy layouts reuse layout nodes, which are internal objects representing UI tree nodes.
  • This allows for potential optimizations like skipping re-measuring or re-drawing if parts of items haven't changed.
ADVICE

LazyColumn vs. RecyclerView

  • Use LazyColumn in Compose apps instead of RecyclerView.
  • Profile your app with baseline profiles in release builds to identify performance bottlenecks.
