Drehen Sie AutoCompleteTextView in einen SearchView in der ActionBar statt

Ich habe eine AutoCompleteTextViewdie gibt dem Benutzer die auto-Vervollständigung Suche Ergebnis aus Google Places API. Sobald ich fertig war, entdeckte ich SearchView und wie es platziert werden kann, in der ActionBar. Ich überprüfte die SearchView Beispiel von google zur Verfügung gestellt und fügte hinzu, es auf meine Anwendung als Ausgangspunkt (es listet die installierten Anwendungen), aber ich weiß nicht, wie zu fahren von hier. Ich möchte die gleiche Funktionalität wie AutoCompleteTextView, sondern verwenden Sie die SearchView statt.
Jede Anregung?
Die ganze Klasse ist weiter unten.
