# Android XML Views Standards
## **Priority: P1**
## Implementation Guidelines
### ViewBinding
- **Standard**: Use ViewBinding for all XML layouts.
- **Synthetics**: `kotlin-android-extensions` Dead. Remove it.
- **KAPT**: Avoid DataBinding unless strictly necessary (impacts build speed).
### RecyclerView
- **Adapter**: Always inherit `ListAdapter` (wraps AsyncListDiffer).
- **Updates**: Provide proper `DiffUtil.ItemCallback`. NEVER call `notifyDataSetChanged()`.
### Layouts
- **ConstraintLayout**: Use for complex flat hierarchies.
- **Performance**: Avoid deep nesting (LinearLayout inside LinearLayout).
## Anti-Patterns
- **No findViewById**: Deprecated. Use ViewBinding for all XML layouts.
- **No kotlin-android-extensions**: Deprecated. Remove all `import kotlinx.android.synthetic.*`.
