how to hide or remove actionbar icon when moving to favorite fragment?

Solution

You just need to make your FavoriteFragment options menu aware and then in onCreateOptionsMenu, simply clear the menu. this can be done by updating FavoriteFragment with following changes

In onCreateView, call setHasOptionsMenu(true) to receive options menu related callbacks in Fragment

override fun onCreateView(inflater: LayoutInflater, container: ViewGroup?,
                              savedInstanceState: Bundle?): View? {
    // Allows your fragment to receive options menu related callbacks (onCreateOptionsMenu etc)
    setHasOptionsMenu(true)
    ...
}

now override onCreateOptionsMenu and clear the already populated menu as

override fun onCreateOptionsMenu(menu: Menu, inflater: MenuInflater) {
    super.onCreateOptionsMenu(menu, inflater)
    menu.clear()
}
