| -------------------- | ------------------------------------- | -------------------------------------------------------------- |
| **Basics** | Tags, Attributes, Nesting | `content` |
| | Well-formed vs Valid XML | Well-formed = correct syntax; Valid = follows schema (DTD/XSD) |
| | Common Uses | Data storage, configs, **Android layouts** |
| **Layouts** | LinearLayout | Vertical/Horizontal stacking |
| | RelativeLayout | Position views relative to each other |
| | ConstraintLayout | Flexible, modern, supports chains, bias, guidelines |
| | Others | FrameLayout, TableLayout, GridLayout |
| **UI Widgets** | TextView, EditText, Button, ImageView | Core UI elements |
| | RecyclerView / ListView | Show lists of items |
| | CheckBox, RadioButton, Switch | User input toggles |
| **View Attributes** | `id`, `layout_width`, `layout_height` | Must-have attributes |
| | Padding, Margin, Gravity | Spacing & alignment |
| | `textSize`, `textColor`, `background` | Styling |
| **Styles & Themes** | `styles.xml`, themes, dark mode | Centralized design control |
| **Drawable XML** | Shape (rectangle, oval, gradient) | Custom backgrounds |
| | Selector | Different states (pressed, focused, etc.) |
| | Layer-list, Ripple | Layered & touch feedback |
| **Values XML** | `strings.xml` | All text resources |
| | `colors.xml` | Centralized color definitions |
| | `dimens.xml` | Centralized sizes (dp, sp) |
| | `styles.xml` | Theme & style definitions |
| **Menus** | Options Menu | `menu.xml` for activity menus |
| | Context Menu | Right-click/long-press menus |
| | Toolbar/ActionBar | Navigation menus |
| **Animations (XML)** | Tween | Scale, rotate, translate, alpha |
| | Drawable | Frame-based (`animation-list`) |
| | MotionLayout | Animations + transitions with constraints |
| **Custom Views** | `attrs.xml` | Define custom attributes |
| | Inflate custom view | Use XML + Kotlin together |
| **Extra Concepts** | XML Namespaces | `xmlns:android=...`, `xmlns:app=...` |
| | ConstraintLayout Advanced | Chains, bias, guidelines |
| | Data Binding | ` ... @{user.name}` |
| | Jetpack Compose | Kotlin-based UI alternative |
