ConstraintLayout 2.0
summary
ConstraintLayout 2.0 adds MotionLayout (alpha) as a drop‑in replacement that moves animation state into a MotionScene XML with transitions, keyframes and key attributes, plus a planned visual keyframe editor in Android Studio. It demonstrates concrete tricks: three screens rebuilt with just six key attributes to tidy a poster animation, a YouTube‑style two‑fragment swipe implemented with motion listeners to sync progress, and coordinate modes (parent/path/delta) that explain surprising axis flips; it’s practical but still alpha.
