Darwind's answer will do the job but that only works when user presses the back button to close the keyboard and when SearchView doesn't have focus anymore.

The better way to do it is to listen for SearchView's text changes.
This way you can restore views and control UI as the text is updating.
here's how I do it.

SearchView searchView = new SearchView(context);
searchView.setOnQueryTextListener(new SearchView.OnQueryTextListener() {
    @Override
    public boolean onQueryTextSubmit(String query) {
        // this is when user is done typing and clicks search
        return false;
    }

    @Override
    public boolean onQueryTextChange(String newText) {
        // you can use this to do a "live" search while the user is typing.
        // this will trigger each time user changes (adds or removes) text
        // so when newText is empty, restore your views
        return false;
    }
});
