UIs f'Android jinbnew minn Views (widgets tal-UI bħal buttons, test) arranġati minn ViewGroups/layouts (kontenituri bħal LinearLayout, ConstraintLayout). Tradizzjonalment definiti f'XML layouts, Android modern l-iktar jużi Jetpack Compose (deklarattiv). Nifhem is-sistema tal-view huwa fundamentali għall-bini ta' UIs.
Views u ViewGroups
VIEW → a single UI element (TextView, Button, ImageView, EditText, etc.)
VIEWGROUP → a container that holds/arranges child views (LinearLayout, ConstraintLayout,
FrameLayout, RecyclerView, etc.) — layouts ARE ViewGroups
→ UIs are a TREE of views inside view groups (composition).
