Fragments

 Fragments

Fragments are self-contained UI components that can be combined to create a single activity. Fragments can be used to create flexible and responsive layouts that can adapt to different screen sizes and orientations.

Here's an example of how to create a simple fragment:

java

public class MyFragment extends Fragment {

   @Override

   public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {

       View view = inflater.inflate(R.layout.fragment_layout, container, false);

       return view;

   }

}

In the above example, we have defined a fragment called "MyFragment". In the onCreateView method, we inflate a layout called "fragment_layout" and return the view.

To add the fragment to an activity, use the following code:

scss

FragmentManager fragmentManager = getSupportFragmentManager();

FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction();

MyFragment fragment = new MyFragment();

fragmentTransaction.add(R.id.fragment_container, fragment);

fragmentTransaction.commit();

In the above example, we create a FragmentManager and FragmentTransaction objects, create an instance of the MyFragment class, and add it to the activity using the add method of the FragmentTransaction object.
