8/15/2023 0 Comments Fragment lifecycleOnDetach(): This method called after onDestroy() method to notify that the fragment has been disassociated from its hosting activity means Fragment is detached from its host Activity. This method called after onDestroyView() method. OnDestroy(): This method is called to do final clean up of the Fragment’s state but Not guaranteed to be called by the Android platform. OnDestroyView(): This method is called when the view and other related resources created in onCreateView() method is removed from the activity’s view hierarchy and destroyed. it occurs either after the fragment is about to be removed or Fragment Transition is processed(replace Fragment) or when the host activity stops. This method calls when the Fragment is no longer visible. OnStop(): This method is called after onPause() method.Fragment going to be stopped by calling onStop(). It occurs when any Fragment Transition processed or Fragment is removed. OnPause(): This method is the first indication that the user is leaving the current fragment or fragment is no longer interactable. OnResume(): This method is called when the Fragment is visible and intractable. OnStart(): This method is called once the fragment gets visible. This method indicates that the activity’s onCreate() has completed. OnActivit圜reated(): This method is called after the onCreateView() method when the host activity is created. We can also return null if the fragment does not provide a UI.

To draw a UI for our fragment we must return a View component from this method that is the root of our fragment’s layout. fragment-lifecycle Star Here are 31 public repositories matching this topic. The following diagram outlines the lifecycle of the Fragment. For example, when an Activity pauses, all of its associated Fragments are paused. OnCreateView(): The will be called when it’s time for the fragment to draw its UI(user interface) for the first time. Fragments have their own lifecycle that is somewhat independent of, but still affected by, the lifecycle of the hosting Activity. It means when a new fragment instance initializes, which always happens after it attaches to the host. OnCreate(): This will be called when creating the fragment. This method let us know that our Fragment has been attached to an activity. OnAttach(): The fragment instance is associated with an activity instance.This method is called first, even before onCreate() method. A fragment must always be embedded in an activity and the fragment’s life-cycle is directly affected by the host activity’s life-cycle.įragments have their own life cycle very similar to an Activity but it has extra events that are particular to the Fragment’s view hierarchy, state and attachment to its activity. We can combine multiple Fragments in single Activity to build a multi pane UI and reuse a Fragment in multiple Activities. It represents a behavior or a portion of user interface in an Activity. It will not be wrong if we say a fragment is a kind of sub-activity. The log is as follows after orientation changes. I'm obviously missing something - like detatching the fragment and reattaching it rather than creating a new instance, but I can't see any documentation which would indicate where I'm going wrong.Ĭan anyone shed some light on what I'm doing wrong here please. The logs from the orientation changes are weird, with multiple calls to the fragments OnCreateView. Using the compatibility package to target 2.2 using Fragments.Īfter recoding an activity to use fragments in an app I could not get the orientation changes/state management working so I've created a small test app with a single FragmentActivity and a single Fragment.
