Question

If the user interface for a fragment uses Preference objects instead of View objects, the fragment needs to extend the ________________ class instead of the Fragment class.

Answer 1

When a fragment in Android utilizes Preference objects for its user interface, it should extend the PreferenceFragmentCompat class to manage and display preferences properly.

Step-by-step explanation:

If the user interface for a fragment uses Preference objects instead of View objects, the fragment needs to extend the PreferenceFragmentCompat class instead of the Fragment class. This is the specialized subclass of Fragment for creating preference hierarchies within an activity. Extending PreferenceFragmentCompat allows a fragment to display a hierarchy of Preference objects as a list, manage the Preference objects, and handle the persistence of their states. This is essential in Android development for creating settings screens.
