Answer from AI
The lifecycle of a View in Android includes several key stages:
- Creation (Initialization) — The View is created, usually via XML layout or programmatically.
- Measurement (Measure) — The system calls the
onMeasure()method to determine the size of the View considering parent constraints. - Layout (Layout) — The
onLayout()method is called, where the View receives coordinates for placement within the parent. - Drawing (Draw) — The
onDraw()method is called, where the View's content is rendered on the screen. - Event Handling — The View can handle user events, such as touches.
These stages repeat when the interface state changes, for example, when sizes change or data is updated.
