Let's sprinkle some #PerfMatters on our ViewGroups (fr)
summary
Claims that replacing generic layouts and TextViews with a purpose-built flat ViewGroup and direct text drawing using Android text layouts yields real, measurable gains. Uses systrace and Hierarchy Viewer to find expensive layout passes, then implements a custom onMeasure/onLayout and draws text with StaticLayout on the canvas to avoid per-child layout and heavy view inflation. Targets the 16ms frame budget for 60fps, shows far fewer missed frames on devices like the Moto G, and verifies improvements with frame stats.
