Life Cycle of a Fragment methods
Description
When a fragment is being created, it goes through the following states:
- onAttach()
- onCreate()
- onCreateView()
- onActivityCreated()
When the fragment becomes visible, it goes through these states:
- onStart()
- onResume()
When the fragment goes into the background mode, it goes through these states:
- onPause()
- onStop()
When the fragment is destroyed (when the hosting activity is destroyed), it goes through the following states:
- onPause()
- onStop()
- onDestroyView()
- onDestroy()
- onDetach()
You can restore an instance of a fragment using a Bundle object, in the following states:
- onCreate()
- onCreateView()
- onActivityCreated()
We can save a fragment's state in the onSaveInstanceState() method.
Difference
Most of the states experienced by a fragment are similar to those of activities. A few new states are specific to fragments:
- onAttached() is called when the fragment has been associated with the activity
- onCreateView() is called to create the view for the fragment
- onActivityCreated() is called when the activity's onCreate() method has been returned
- onDestroyView() is called when the fragment's view is being removed
- onDetach() is called when the fragment is detached from the activity
