Gire AutoCompleteTextView en un SearchView en ActionBar en su lugar

Tengo un AutoCompleteTextView que proporciona resultados de búsqueda de autocompletado del usuario de la API de Google Places . Una vez que terminé descubrí SearchView y cómo se puede colocar en ActionBar . Comprobé el ejemplo de SearchView proporcionado por google y lo añadí a mi aplicación como punto de partida (enumera las aplicaciones instaladas) pero no sé cómo proceder desde aquí. Quiero tener la misma funcionalidad que AutoCompleteTextView pero usar el SearchView en su lugar. ¿Cualquier sugerencia? La clase entera se proporciona a continuación.

Después de actualizar el código sugerido por saxman, puedo ver que el método de consulta en el proveedor nunca se llama:

• Searchview que no cierra correctamente en la PRIMERA prensa trasera (es solamente perdida del foco)
• Quitar icono de la vista de búsqueda del texto de la pista
• Enviar una consulta cuando haga clic en el botón de búsqueda en el teclado
• SearchView en OptionsMenu no es el ancho completo
• No se puede obtener la vista de búsqueda en la barra de acciones para trabajar

Mi archivo de manifiesto tiene este aspecto:

Utilizo la misma autoridad en el manifiesto, proveedor de contenido y archivo de manifiesto. Veo el searchView en el menú y no he modificado el método de la consulta así que debe apenas volver el cursor de una línea. Pero el método de consulta nunca se llama. por favor ayuda. Otro problema que acabo de detectar es que el searchView no muestra el search_hint especificado!
