In style

Answer 1

If you change android:actionViewClass to app:actionViewClass your existing code will continue working.

Answer 2

You should use the static methods in MenuItemCompat do deal with all AppCompat menu items. This was mentioned in this blog post as the last item under 'New Integration'. Just replace your SearchView declaration with the following.

SearchView searchView = (SearchView) MenuItemCompat.getActionView(menu.findItem(R.id.action_search));

Here's a link to the MenuItemCompat documentation.

Edit: I just assumed you are using the latest version of AppCompat with the support for the new Toolbar widget.
