The Curious Case of Android Button
summary
Yelp measures tens of millions clicks a day and tunes every pixel: shadow elevations, ripple animations, padding insets and color layers. The code dive traces actual framework assets—inset drawable, gradient shape, theme attributes—and shows how buttons resolve colors via ColorStateList and animate with StateListAnimator (elevation + translation for press/disabled). The team builds a small utilities layer that emits proper state lists, defines five button styles across products, and reports that using styles and theme overlays fixes inconsistent disabled visuals and supports runtime color changes.
