Setting hint text for search widget when used as part of menu
<p>I have a menu item as part of my action bar menu, and I am setting the action view class to the search widget like so:</p>

<pre><code>   &lt;item android:id="@+id/menu_search"
        android:title="Search"
        android:icon="@drawable/ic_menu_search"
        android:showAsAction="always"
        android:actionViewClass="android.widget.SearchView" /&gt;
</code></pre>

<p>This makes the search widget pop out when it is clicked - however, I want it to always be visible, and I also want to be able to set the query hint etc.</p>

<p>When I attempt to call <code>SearchView searchItem = (SearchView) menu.findItem(R.id.menu_search)</code>      to get a reference to it, it throws an error as the item cannot be cast to a <code>SearchView</code>.</p>
