Conquering Common Conundrums with ConstraintLayout
summary
Notes how ConstraintLayout treats dimensions: avoid match_parent and use 0dp (match_constraint) which unlocks attributes like DimensionRatio and bias; use constraintWidth=true or constraintHeight to prefer match-constraint when wrap-content would break constraints. Use Baseline for text alignment, Barrier for dynamic edge guarding, and Guidelines for reusable keylines. Treat chains sparingly (only for spacing behavior); use Flow as a Flow (flexbox-like) wrapper to get wrapping layouts. These techniques reduce brittle hacks and make layouts adapt.
