Remove old Fragment from fragment manager

Question

I'm trying to learn how to use Fragments in android. I'm trying to remove old fragment when new fragment is calling in android.

Answer 1

You need to find reference of existing Fragment and remove that fragment using below code. You need add/commit fragment using one tag ex. "TAG_FRAGMENT".

Fragment fragment = getSupportFragmentManager().findFragmentByTag(TAG_FRAGMENT); if(fragment != null)     getSupportFragmentManager().beginTransaction().remove(fragment).commit(); 

That is it.

Answer 2

If you want to replace a fragment with another, you should have added them dynamically, first of all. Fragments that are hard coded in XML, cannot be replaced.

// Create new fragment and transaction Fragment newFragment = new ExampleFragment(); FragmentTransaction transaction = getFragmentManager().beginTransaction();  // Replace whatever is in the fragment_container view with this fragment, // and add the transaction to the back stack transaction.replace(R.id.fragment_container, newFragment); transaction.addToBackStack(null);  // Commit the transaction transaction.commit();
