    I've used onPrepareOptionsMenu in this way to achieve what you are trying to do. (not tested but should give you an idea.)

    private boolean mIsLoading = true;
    
    @Override
    public void onPrepareOptionsMenu(Menu menu) {
        super.onPrepareOptionsMenu(menu);
        refresh = (MenuItem) menu.findItem(R.id.menu_item_refresh);
        if (!mIsLoading) {
            refresh.setActionView(null);
        }
    }
    
    @Override
    public void onLoadFinished(Loader loader, Cursor data) {
        mAdapter.swapCursor(data);
        mIsLoading = false;
        getActivity().invalidateOptionsMenu();
    }
