Answer 1

Not sure if this is what you want, but I have a fragment which opens a new Actvity (with a fragment inside):

 public boolean onOptionsItemSelected(MenuItem item)
{
    switch(item.getItemId())
    {
        case R.id.action_about:
         Intent intent_to = new Intent(getActivity(),MyNewActivity.class);
            startActivity(intent_to);
            break;

    }
    return true;
}

Inside MyNewActivity class you should have a container and open a fragment using getFragmentManager()

You can even use startActivityForResult if you want to do something depending in how the new fragment closes

Hope it helps

Old question but WTH.You do this using a FragmentManager and her friend FragmentTransaction :

@Override
public boolean onOptionsItemSelected(MenuItem item){
   switch (item.getItemId()){

    case R.id.action_reset:

        Unsafe.uhs1a.setSelection(0);
        Unsafe.uhs1b.setSelection(0);
        Unsafe.uhs1c.setSelection(0);
        Precondition.phs1a.setSelection(0);
        Precondition.phs1b.setSelection(0);
        Precondition.phs1c.setSelection(0);

    case R.id.action_about:
      Fragment newFragment = new TheFragmentYouWantToOpen();
      FragmentManager fragmentManager = getFragmentManager();
      FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction();
            fragmentTransaction.replace(R.id.frame_container, newFragment);
            fragmentTransaction.addToBackStack(null);
            fragmentTransaction.commit();
    //frame_container is the id of the container for the fragment
    return true;
    default:
        return super.onOptionsItemSelected(item);
}
