ConstraintLayout 2.0

on YouTube ↗41m

" summary

ConstraintLayout 2.0 claims faster layout by optimizing the constraint model and sometimes bypassing the solver, adds virtual viewgroups like Flow virtual layout for responsive chains and wrapping, and exposes declarative motion via MotionLayout with separate MotionScene files, keyframes, key cycles and time cycles, plus features like target matching, region swiping and auto transitions. Motion editor work is postponed but a Cycle Editor demo and many GitHub examples exist, and MotionLayout integrates into existing apps and RecyclerViews so complex coordinated animations are practical and reproducible.
