final SearchView searchView = (SearchView) menu.findItem(R.id.menu_search).getActionView();

My method is

    super.onCreateOptionsMenu(menu, inflater);
    inflater.inflate( R.menu.menu_search, menu);
    System.out.println( "inflating menu");

    final SearchView.OnQueryTextListener queryTextListener = new SearchView.OnQueryTextListener() {
        @Override
        public boolean onQueryTextChange(String newText) {
            showFilteredItems( newText );
            return true;
        }

        @Override
        public boolean onQueryTextSubmit(String query) {

If you are using AppCompat library, then in your menu.xml, add

app:actionViewClass="android.support.v7.widget.SearchView"

instead of

app:actionViewClass="android.widget.SearchView"

Some times problem is with

setHasOptionsMenu(true);

Move it from oncreate or onviewcreate to on attached method and try it.

If you are using the Appcompat library, maybe you forgot to add your own xmlns on your menu_search.xml.

As the example says: 

<menu xmlns:android="http://schemas.android.com/apk/res/android"
  xmlns:yourapp="http://schemas.android.com/apk/res-auto" >
<!-- Search, should appear as action button -->
<item android:id="@+id/action_search"
      android:icon="@drawable/ic_action_search"
      android:title="@string/action_search"
      yourapp:showAsAction="ifRoom"  />
</menu>

You need to add the folowing:

<item android:id="+@id/..."
      android:actionViewClass="android.widget.SearchView"
      yourapp:actionViewClass="android.widget.SearchView" />

To reference a layout from a menu xml use the actionLayout attribute:

<menu>
<item android:id="@+id/menu_name"
  android:actionLayout="@layout/your_layout"
  android:showAsAction="always"/>
</menu>
