Deep dive into MotionLayout
summary
MotionLayout (ConstraintLayout 2.0 alpha3) lets layouts animate declaratively via a separate motionScene XML that holds constraintSets, transitions, and key controls. It supports keyPosition/keyAttribute keyframes, key cycle/time cycle oscillations (sine/cosine for circular motion) with monotonic splines to avoid overshoot, and custom attributes for color/rotation. Alpha4 plans rename some attributes, add visibility opt-out, better resize behavior and initial RecyclerView choreography tools so items can animate into full-screen without rewriting UI.
