Android UI How to - Life Cycle of a Fragment methods

• Back to Fragment  ↑

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
