FragmentLifecycleCallbacks

<init>

FragmentLifecycleCallbacks()

Callback interface for listening to fragment state changes that happen within a given FragmentManager.

onFragmentActivityCreated

open fun onFragmentActivityCreated(
    @NonNull fm: FragmentManager, 
    @NonNull f: Fragment, 
    @Nullable savedInstanceState: Bundle?
): Unit

Deprecated: To get a callback specifically when a Fragment activity's android.app.Activity#onCreate(Bundle) is called, register a androidx.lifecycle.LifecycleObserver on the Activity's Lifecycle in onFragmentAttached(FragmentManager, Fragment, Context), removing it when it receives the Lifecycle.State#CREATED callback.

Called after the fragment has returned from the FragmentManager's call to Fragment#onActivityCreated(Bundle). This will only happen once for any given fragment instance, though the fragment may be attached and detached multiple times.

onFragmentAttached

open fun onFragmentAttached(
    @NonNull fm: FragmentManager, 
    @NonNull f: Fragment, 
    @NonNull context: Context
): Unit

Called after the fragment has been attached to its host. Its host will have had onAttachFragment called before this call happens.

onFragmentCreated

open fun onFragmentCreated(
    @NonNull fm: FragmentManager, 
    @NonNull f: Fragment, 
    @Nullable savedInstanceState: Bundle?
): Unit

Called after the fragment has returned from the FragmentManager's call to Fragment#onCreate(Bundle). This will only happen once for any given fragment instance, though the fragment may be attached and detached multiple times.

onFragmentDestroyed

open fun onFragmentDestroyed(
    @NonNull fm: FragmentManager, 
    @NonNull f: Fragment
): Unit

Called after the fragment has returned from the FragmentManager's call to Fragment#onDestroy().

onFragmentDetached

open fun onFragmentDetached(
    @NonNull fm: FragmentManager, 
    @NonNull f: Fragment
): Unit

Called after the fragment has returned from the FragmentManager's call to Fragment#onDetach().

onFragmentPaused

open fun onFragmentPaused(
    @NonNull fm: FragmentManager, 
    @NonNull f: Fragment
): Unit

Called after the fragment has returned from the FragmentManager's call to Fragment#onPause().

onFragmentPreAttached

open fun onFragmentPreAttached(
    @NonNull fm: FragmentManager, 
    @NonNull f: Fragment, 
    @NonNull context: Context
): Unit

Called right before the fragment's Fragment#onAttach(Context) method is called. This is a good time to inject any required dependencies or perform other configuration for the fragment before any of the fragment's lifecycle methods are invoked.

onFragmentPreCreated

open fun onFragmentPreCreated(
    @NonNull fm: FragmentManager, 
    @NonNull f: Fragment, 
    @Nullable savedInstanceState: Bundle?
): Unit

Called right before the fragment's Fragment#onCreate(Bundle) method is called. This is a good time to inject any required dependencies or perform other configuration for the fragment.

onFragmentResumed

open fun onFragmentResumed(
    @NonNull fm: FragmentManager, 
    @NonNull f: Fragment
): Unit

Called after the fragment has returned from the FragmentManager's call to Fragment#onResume().

onFragmentSaveInstanceState

open fun onFragmentSaveInstanceState(
    @NonNull fm: FragmentManager, 
    @NonNull f: Fragment, 
    @NonNull outState: Bundle
): Unit

Called after the fragment has returned from the FragmentManager's call to Fragment#onSaveInstanceState(Bundle).

onFragmentStarted

open fun onFragmentStarted(
    @NonNull fm: FragmentManager, 
    @NonNull f: Fragment
): Unit

Called after the fragment has returned from the FragmentManager's call to Fragment#onStart().

onFragmentStopped

open fun onFragmentStopped(
    @NonNull fm: FragmentManager, 
    @NonNull f: Fragment
): Unit

Called after the fragment has returned from the FragmentManager's call to Fragment#onStop().

onFragmentViewCreated

open fun onFragmentViewCreated(
    @NonNull fm: FragmentManager, 
    @NonNull f: Fragment, 
    @NonNull v: View, 
    @Nullable savedInstanceState: Bundle?
): Unit

Called after the fragment has returned a non-null view from the FragmentManager's request to Fragment#onCreateView(LayoutInflater, ViewGroup, Bundle).

onFragmentViewDestroyed

open fun onFragmentViewDestroyed(
    @NonNull fm: FragmentManager, 
    @NonNull f: Fragment
): Unit

Called after the fragment has returned from the FragmentManager's call to Fragment#onDestroyView().
