Android XML Views Standards

Priority: P1

Implementation Guidelines

ViewBinding

  • Standard: Use ViewBinding for all XML layouts.
  • Synthetics: kotlin-android-extensions is Dead. Remove it.
  • KAPT: Avoid DataBinding unless strictly necessary (impacts build speed).

RecyclerView

  • Adapter: Always inherit ListAdapter (wraps AsyncListDiffer).
  • Updates: Provide a proper DiffUtil.ItemCallback. NEVER call notifyDataSetChanged().

Layouts

  • ConstraintLayout: Use for complex flat hierarchies.
  • Performance: Avoid deep nesting (LinearLayout inside LinearLayout).

Anti-Patterns

  • findViewById: **Deprecated**: Use ViewBinding.
  • Synthetics: **Deprecated**: Remove import kotlinx.android.synthetic.*.
