android-layouts

What problem does it solve?

This Skill eliminates the common pain points of slow, inefficient Android layouts—both legacy XML/View systems and modern Jetpack Compose—that suffer from deep view hierarchies, double measurement overhead, incorrect modifier ordering, poor View-Compose interop, and improper inset handling, leading to janky UI and poor user experience.

Core Features & Use Cases

• XML Layout Optimization: Guidance on flattening hierarchies, using ConstraintLayout, merge/include, ViewStub, avoiding double taxation in weighted LinearLayouts, and implementing RecyclerView and CoordinatorLayout patterns.
• Compose Layout Best Practices: Covers layout phases, modifier order, WindowInsets handling, lazy layout content padding, custom layouts, SubcomposeLayout use cases, and adaptive layouts with WindowSizeClass for foldables and varying screen sizes.
• View-Compose Interop: Patterns for incremental migration including embedding Compose in XML via ComposeView, embedding XML views in Compose via AndroidView and AndroidViewBinding, and common interop pitfalls to avoid.
• Use Case: For example, if you are optimizing a news app's home screen that is experiencing layout jank on low-end devices, use this Skill to flatten the XML hierarchy, replace nested weighted LinearLayouts with ConstraintLayout, and verify no double taxation is occurring. For a new Compose feature screen, use it to ensure correct modifier order, proper WindowInsets handling, and efficient LazyColumn implementation.

Quick Start

Use the android-layouts skill to review your existing Android app's layout files for performance bottlenecks and implement recommended optimizations for both XML and Compose screens.
