Fragments

A Fragment represents a behavior or a portion of user interface in an Activity You can combine multiple fragments in a single activity to build

a multi-pane UI and reuse a fragment in multiple activities You can think of a fragment as a modular section of an activity, which has its own lifecycle, receives its own input events, and which you can add or remove while the activity is running (sort of like a "sub activity" that you can reuse in different activities).

Fragments – Lifecycles

onCreate—This method is called when a Fragment is created The MainActivityFragment and SettingsActivityFragment are created when the app

inflates their parent activities’ layouts The DialogFragment that displays the quiz results is created and displayed dynamically when the user completes a quiz

onCreateView—This method (which you’ll override in class MainActivityFragment) is called after onCreate to build and return a View containing the

Fragment’s GUI As you’ll see, this method receives a LayoutInflater, which you’ll use to programmatically inflate a Fragment’s GUI from the

components specified in a predefined XML layout.
