        setMenuItemState(R.string.pizzasList_viewShoppingCart, true,
                !isShoppingCartEmpty());

        MenuItem item = menuItemsMap.get(itemTitleResID);
        item.setEnabled(enabled);
        item.setVisible(visible);
    }

    @Override
    public boolean onOptionsItemSelected(MenuItem item) {
        if (item.getTitle().equals(getString(R.string.pizzasList_viewUserData))) {
            showUserDataActivity();

        } else if (item.getTitle().equals(
                getString(R.string.pizzasCart_pizzasList))) {
            showPizzasListActivity();

        } else if (item.getTitle().equals(
                getString(R.string.pizzasList_viewShoppingCart))) {
            showPizzasCartListActivity();

        } else if (item.getTitle().equals(
                getString(R.string.pizzasCart_checkout))) {
            checkoutShoppingCartPromptUser();
        }
