Answer from AI
The lifecycle of a View in Android includes several key stages:
- Creation (Inflation) — The View is created from XML layout or programmatically.
- Measurement (Measure) — The system determines the size of the View considering parent constraints.
- Layout — The View receives coordinates for display on the screen.
- Drawing (Draw) — The View is rendered on the screen.
- Event Handling — The View responds to user actions (clicks, gestures).
- Update (Invalidate/RequestLayout) — When the View's state changes, it may request a redraw or re-layout.
- Removal (Detach/Destroy) — The View is removed from the hierarchy, and resources are released.
Understanding these stages is important for optimizing performance and ensuring the correct operation of the user interface.
