Answer from AI
The lifecycle of a Fragment in Android consists of several key stages that manage the creation, display, and destruction of the fragment:
- onAttach() — the fragment is attached to an Activity.
- onCreate() — initializing the fragment, creating necessary data.
- onCreateView() — creating and returning the View hierarchy for the fragment.
- onViewCreated() — called after the View is created, can initialize UI elements.
- onActivityCreated() — the Activity and fragment are fully created, can work with Activity data.
- onStart() — the fragment becomes visible to the user.
- onResume() — the fragment is active and interacting with the user.
When leaving the screen, the reverse methods are called:
- onPause() — the fragment is no longer active.
- onStop() — the fragment is no longer visible.
- onDestroyView() — the View of the fragment is destroyed.
- onDestroy() — resources of the fragment are released.
- onDetach() — the fragment is detached from the Activity.
These stages allow managing resources and the state of the fragment at different times in its lifecycle.
