What's new in ConstraintLayout
summary
ConstraintLayout 2 adds concrete features: MotionLayout animates between full constraint sets with keyframes, key attributes and key cycles; the team ships 2.0 beta1 and a MotionScene XML model plus a Motion Editor for Android Studio. Virtual helpers like Flow virtual layout handle wrapping/chaining without extra view groups. Runtime APIs such as ConstraintSet let code swap states; examples include draggable RecyclerView item expansion and multi-state swipe carousels that run smoothly.
