If you start again a particular fragment, after the onStop() method, it will begin from the onStart() method. When the fragment closes, these methods start to work: onPause(), onStop(), onDestroyView(), onDestroy(), onDetach(). Now with the onResume() method, the fragment continues to work. After that, these three methods start to work, onViewCreated(), onStart(), onResume(). So, when a fragment first starts, these three methods start to work onAttach(), onCreate(), onCreateView(). We're going to talk about this particular life cycle right now. So, that means the fragment has a life cycle from the moment it was created to the moment it was closed. So, we've got to continue with the life cycles because that's what we got to do. And you know what? I think that's enough right now about fragments. Also, you can use one fragment in more than one activity. For example, you can create fragments as much as you want in one activity. And because of that, developers prefer using fragments. So, fragments are the more useful and more dynamic user interfaces. You can find fragments as small activity particles. Fragments are basically a user interface that works in the activity. So, fragments are presented to the developer after API level 11. In this particular video, we just want to talk about life cycles and fragment first, okay? So just a little bit of information about fragments. We're not going to go into too much detail about fragments. We're going to talk about the life cycle in fragments, all right? So, we will discuss fragments in detail in the following videos. This fragment displays a list of items using a RecyclerView.Hello everyone. Toast.makeText(getActivity(), “Button clicked”, Toast.LENGTH_SHORT).show() View view = inflater.inflate(R.agment_button, container, false) īutton button = view.findViewById(R.id.button) public class ButtonFragment extends Fragment implements View.OnClickListener View onCreateView(LayoutInflater inflater, ViewGroup container,.This fragment contains a single button that displays a Toast message when clicked. Here are some Android fragments examples. To learn more about fragment in android and how it is used, you can opt for an Android development course. This approach is used by the system to separate the fragment from its host activity. This is triggered to perform the final cleanup of the fragment and its lifecycle. The system invokes this method to remove any resources and view hierarchies associated with the fragment. This is a technique to remove the fragment from the user’s screen and end its operation. It shows that the user is navigating away from the fragment. This method is called to make the fragment interactive. This method is used by the system to display the fragment on the user’s device. This shows that the activity has been created where the fragment exists. This method is invoked by the system to build the fragment’s user interface. With this function, the fragment is initialized by adding all necessary components and attributes. It is executed only once during the lifetime. This is the first method executed after the fragment has been linked to the activity. The fragment lifecycle in Android has the following methods: Method The lifecycle methods of an activity, such as onCreate() and onDestroy, are also available to a fragment when it is added to an activity(). It is essential to keep in mind that the Activity lifecycle and the Fragment lifecycle are interconnected. This can be done by putting the proper lifecycle methods into place. You can ensure that your pieces operate as expected and release resources when they are no longer required. Understanding the fragment lifecycle is essential for Android applications that employ fragments to function effectively and efficiently. It makes them more adaptable and user-friendly.Īlso Read: List Of Android Version Fragment Lifecycle in Android Screen Support: Applications that can adjust to various screen sizes and orientations can be made using fragments.It reduces the amount of time and effort required for development. Reusability: The ability to reuse fragments across multiple activities and layouts enables a more modular design approach.Simplified Code: Developers can write cleaner, more manageable code that is simpler to maintain and debug by breaking complex user interfaces into smaller bits.It is a modular component of activity with its own user interface, behavior, and lifecycle.įragments offer several advantages over traditional user interface design. It is done to form a multi-pane user interface in Android programming. A fragment is a piece of an activity’s user interface that can be reused and merged with other fragments.
