ListView - RecyclerView

on YouTube ↗25m

" summary

Facebook reworks News Feed from Android ListView to the Support Library RecyclerView, building a migration library (GitHub: FBampleview to recyclerview) and running an A/B test to compare both in production. Key changes are splitting view creation/binding, switching to granular notifies, and using SortedList and DiffUtil to emit precise change events. Result: a measurable large scroll‑performance win and richer item animations, plus workarounds for texture‑view video detach issues and a custom recycler to avoid flicker.
