How Can I Dynamically Replace Hard-coded Fragments in Android?

Replacing Fragments Dynamically Within Activity Groups

Replacing fragments within an activity group can pose challenges. This article addresses the issue of swapping one fragment for another when the initial fragment is hard-coded in XML.

Solution

To dynamically replace a fragment, it must have been initially added dynamically. Here's how to achieve this:

// 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();

Note:

• Ensure that R.id.book_description_fragment is a layout container in the parent activity.
• Remove any fragments hard-coded in XML before dynamically adding them.
