How can I recreate a fragment?

If you're using Navigation Component, you can use this:

findNavController().navigate(
    R.id.current_dest,
    arguments,
    NavOptions.Builder()
        .setPopUpTo(R.id.current_dest, true)
        .build()
)

This lets NavController pop up the current fragment and then navigate to itself. You get a new Fragment and fragment ViewModel also gets recreated.

You can use :

getSupportFragmentManager().beginTransaction()
                .replace(R.id.container, LobbyFragment.newInstance()).commit();

To recreate your fragment

Note:getSupportFragmentManager() is if you are using support fragment and AppCompatActivity , if you are using framework fragment class you need to use getFragmentManager()

I'm using .detach() and .attach() for recreating the fragment.

ATTACH

Re-attach a fragment after it had previously been deatched from the UI with detach(Fragment). This causes its view hierarchy to be re-created, attached to the UI, and displayed.

DETACH

Detach the given fragment from the UI. This is the same state as when it is put on the back stack: the fragment is removed from the UI, however its state is still being actively managed by the fragment manager. When going into this state its view hierarchy is destroyed.

HOW I USE IT

getFragmentManager()
        .beginTransaction()
        .detach(LobbyFragment.this)
        .attach(LobbyFragment.this)
        .commit();
