In Android, the fragment is the part of Activity which represents a portion of User Interface (UI) on the screen. It is the modular section of the android activity that is very helpful in creating UI designs that are flexible in nature and auto-adjustable based on the device screen size In Android, a Fragment is a part of an Activity that is used to make the activity design more modular. Therefore, it is easier to understand fragment by thinking of it as a kind of sub-activity. In Android development, a fragment is added with the help of the element. Although it is a part of an activity, a fragment has its own lifecycle and. Suppose we have one activity and in this activity we have one fragment with the name FirstFragment so when it's first load into the activity below Lifecycle event will be called for this fragment. onAttach > onCreate > onCreateView >onViewCreated >onActivityCreated > onStart > onResume of FirstFragment will be called. Now if we have one but A fragment life cycle is closely related to the lifecycle of its host activity which means when the activity is in the pause state, all the fragments available in the activity will also stop. Fragments added to the Android API in Android 3.0 which API version 11 to support flexible UI on large screens. The fragment has its lifecycle which runs.

Similarly, the Fragment class also provides A series of callback methods are used to cover every link in the fragment life cycle. Among them, the callback methods and Android Fragments in the activity Almost all of them, but Android Fragments also provide some additional callback methods, so let's focus on these callbacks 2) Life cycle and life cycle methods of fragment . onAttach() : The fragment instance is associated with an activity instance.The fragment and the activity are not fully initialized.Typically you get in this method a reference to the activity which uses the fragment for further initialization work The Android - Activity (UI Single Screen) lifecycle is implemented by callback methods. A good way to test the lifecycle implementation (ie the application's ability to restore its state) is to simply Android - Screen Rotation the device so that the screen orientation changes

A Fragment represents a behavior or a portion of user interface in an Activity.You can combine multiple fragments in a single activity to build a multi-pane UI and reuse a fragment in multiple activities. You can think of a fragment as a modular section of an activity, which has its own lifecycle, receives its own input events, and which you can add or remove while the activity is running. Form fragments is a brand new feature in LiveCycle Designer ES.In a nutshell, this new feature allows you to extract common elements, such as a form header and footer, across multiple forms and place them in a separate file called a fragment

Because fragments are included in activity, the lifespan of an Android fragment is influenced by the lifecycle of an activity. Because fragments are embedded in activity, each has its own life cycle techniques that are influenced by the activity life cycle.

Lifecycle. When an application is opened and shows its first activity, it follow a specific lifecycle. Within this, you can handle when the activity is destroyed, paused, resumed, or created The fragment lifecycle is shown below: Methods of Android Fragment. Our fragment class needs to implement the following methods for the fragments to work properly. Let us see them one by one: 1. onAttach.

The Android SDK and, by extension, the Xamarin.Android framework provide a powerful model for managing the state of activities within an application. When an activity's state is changing, the activity is notified by the OS, which calls specific methods on that activity. The following diagram illustrates these methods. Create A Fragment Class In Android Studio: For creating a Fragment firstly we extend the Fragment class, then override key lifecycle methods to insert our app logic, similar to the way we would with an Activity class.

  2. Questions: Using the compatibility package to target 2.2 using Fragments.

The logs from the orientation changes are weird, with multiple calls.
  3. The Fragment.setRetainInstance () method control whether a fragment instance is retained across Activity re-creation (such as from a configuration change).

A big thanks to one of our readers- Ramakrishna Joshi for pointing out that OnBackPressedDispatcher is not lifecycle aware. Therefore it expects you to unregister in onDestroyView() of fragment when fragment is destroyed. If it is not unregistered then it keeps a reference and gets called when back is pressed in some other fragment also Fragment can be thought like a sub activity, whereas the complete screen with which user interacts is called as activity. An activity can contain multiple fragments. Fragment are part of an activity. A Fragment is a section of an Activity, which has: · its own lifecycle. · receives its own input events Android Activity Lifecycle: is managing the state of Activity like when its start, stop, user, using, not in front of the user, no more longer. So that all states are managing by call back methods in action. You can override those methods and can do a particular operation to do the best output of your application The activity/fragment lifecycle is really one of the worst parts of developing on Android. Even with the new abstractions like loaders, making sure that state is retained properly is full of corner cases and other hard-to-get-right behavior. No wonder some people just say fuck it and set configChanges in their manifest Fragment life-cycle. A fragment has its own life cycle. But it is always connected to the life cycle of the activity which uses the fragment. If an activity stops, its fragments are also stopped. If an activity is destroyed, its fragments are also destroyed. Table Title. Metho
