in order to have an options menu you need to tell your fragment about it in onCreate after which you override onCreateOptionsMenu. then to handle any clicks on the items override onOptionsItemSelected() your full Activity should look like this:

class TestFragment : Fragment() {
override fun onCreate(savedInstanceState: Bundle?) {
    super.onCreate(savedInstanceState)
    setHasOptionsMenu(true)
}

override fun onCreateOptionsMenu(menu: Menu, inflater: MenuInflater) {
    inflater.inflate(R.menu.menu_test, menu);

    super.onCreateOptionsMenu(menu, inflater)
}

You can also try to use the actionBar widget provided by android incase the appcompat one doesn't work for you
