Why are there separate methods onCreateView and onDestroyView for Fragment in Android instead of using a single method to manage UI?

In Android, separate methods onCreateView and onDestroyView are provided for Fragment to clearly distinguish the stages of creating and destroying the user interface (UI) of the fragment. This is related to the fragment's lifecycle, which can exist independently of its UI.

• onCreateView is called to create and initialize the fragment's UI. Typically, the layout is created and inflated here.
• onDestroyView is called when the fragment's UI is destroyed, but the fragment itself may still remain in memory (for example, when transitioning to another screen while preserving state).

This separation allows for efficient resource management: UI resources can be released without destroying the fragment itself and its data. If there were only one method to manage the UI, it would be more difficult to control the lifecycle and avoid memory leaks or incorrect state restoration.
