How to create button X inside fragment A that will replace fragment A to fragment B

Question

I have fragment A and button X inside it. When I click on button X, the fragment A will be replaced by fragment B? How should I do that? Thank a lot.

Answer 1

public void changeFragment(){
    FragmentTransaction ft = getFragmentManager().beginTransaction();
    xyzFragment fragment = new xyzFragment();
    ft.replace(R.id.details_fragment, fragment );
    ft.setTransition(FragmentTransaction.TRANSIT_FRAGMENT_FADE);
    ft.commit();
}
