the view parameter of onViewCreated() is the inflated view returned from onCreateView().įor most beginner applications you only need to really to understand the CREATED state and the methods it calls. onViewCreated() is the last method called and it is where any view related work should be done. It is in onCreateView() that you can manually inflate the view by using the LayoutInflater class. onCreateView() is called after onCreate() but before onViewCreated(). It is used for reinitializing previously saved data form the savedInstanceState state. Remember that fragments can not exist on their own and must be hosted by either a activity or another fragment.Įnter fullscreen mode Exit fullscreen modeįrom the code above: onCreate() is called right after onAttach() and before the other two methods. Once the fragment has been added to the Fragment Manager, the onAttach() callback is invoked to attach the fragment to it host activity. The Fragment Manager is responsible for determining what state a fragment should be in and then moving it to that state. For a fragment to then transition through the rest of its lifecycle, it must be added to a Fragment Manager. when a fragment is instantiated, it begins in the INITIALIZED state.As the user navigates and interacts with the app, the fragment transitions through 5 possible phases. Each fragment that gets created has it's own lifecycle. I also want to stress again, this is a very simplified version of the Fragment lifecycle, so please read the documentation HERE if you want a deeper understanding.
