Grokking the contrastaint layout

on YouTube ↗45m

" summary

Demo-heavy coverage of ConstraintLayout and the revamped layout editor in Android Studio with concrete claims and caveats: requires Android Studio 2.2+ (recommend 2.4 preview), add one Gradle line, supports chains, guidelines, percent positioning, aspect ratios and a match_constraint (0dp) sizing model; handles view visibility with GONE in chains, but preview can mislead unconstrained views and error coloring shows warnings as red. Shows programmatic edits via ConstraintSet and several editor bugs and workarounds.
