Migrating to ViewPager2? Beware This Invisible Layout Bug

ViewPager2 can render blank pages when migrating from ViewPager due to a layout measurement issue. Unlike the original ViewPager, ViewPager2 relies on RecyclerView and requires a measurable height from its parent layout. If the parent uses wrap_content or weak constraints, ViewPager2 gets assigned 0 height, causing fragments not to render. The fix involves ensuring the parent provides measurable dimensions through match_parent, fixed dp values, or proper ConstraintLayout constraints with 0dp. Special considerations apply when nesting inside ScrollView (disable swipe or use fixed height) and ConstraintLayout (use MATCH_CONSTRAINT with proper constraints).
