What methods can be used to create and display a Fragment in an application?

Creating and displaying a Fragment in Android can be implemented in several ways:

1. Dynamic addition via FragmentManager:

FragmentManager fragmentManager = getSupportFragmentManager();
FragmentTransaction transaction = fragmentManager.beginTransaction();
MyFragment fragment = new MyFragment();
transaction.add(R.id.container, fragment);
transaction.commit();

2. Static addition in XML layout:

<fragment
    android:id="@+id/my_fragment"
    android:name="com.example.MyFragment"
    android:layout_width="match_parent"
    android:layout_height="match_parent" />

3. Replacing a fragment:

FragmentTransaction transaction = getSupportFragmentManager().beginTransaction();
transaction.replace(R.id.container, new MyFragment());
transaction.addToBackStack(null);
transaction.commit();

The choice of method depends on the task: the static method is simpler but less flexible; the dynamic method allows managing fragments during app runtime.
