Android でハードコードされたフラグメントを動的に置き換えるにはどうすればよいですか?

// Create new fragment and transaction
Fragment newFragment = new SectionDescriptionFragment();
FragmentTransaction transaction = getActivity().getSupportFragmentManager().beginTransaction();

// Replace the existing fragment
transaction.replace(R.id.book_description_fragment, newFragment);
transaction.setTransition(FragmentTransaction.TRANSIT_FRAGMENT_OPEN);
transaction.addToBackStack(null); // Optional: Add to back stack for navigation

// Commit the transaction
transaction.commit();
