Fragment screen to call another screen Fragment

Question

I’m in a fragment, and in that fragment I want to call another screen which is also a fragment. I’m using recycleview. If I try to call one activity, I can, but I can’t call a fragment.

See the code below:

@Override
public void onNoteClick(int position) {
    listaCursos.get(position);
   // aqui deve chamar outro fragment
}

I tried some examples I found, but does not open another screen that has the fragment. Just remembering that my app only has one activity, all else only fragment.

Calling the screen using Intent is not my case.

I tried something like this I found and it wasn’t:

Fragment fr = new Fragment();
FragmentManager fm = getFragmentManager();
FragmentTransaction fragmentTransaction = fm.beginTransaction();
fragmentTransaction.replace(R.id.container, fr);
fragmentTransaction.commit();

I will put here as ta my xml:

<?xml version="1.0" encoding="utf-8"?>

Answer 1

You can start another Fragment from the following:

FragmentManager fragmentManager = getActivity().getSupportFragmentManager();
FrgmentTransaction fragmentTransaction = fragmentManager.beginTransaction();
fragmentTransaction.replace(R.id.fragmentContainer,new Fragment2()).commit(); 

Note that R.id.fragmentContainer is your xml frameLayout and Fragment2() is the fragment you want to call;
