Using SearchView

Now that FlickrFetchr supports searching, it is time to add a way for the user to enter a query and initiate a search. Do this by adding a SearchView.

As we said at the beginning of the chapter, SearchView is an action view, meaning your entire search interface can live in your application’s app bar.

Create a new menu XML file for PhotoGalleryFragment called res/menu/fragment_photo_gallery.xml. This file will specify the items that should appear in the toolbar. (See Chapter 14 for detailed steps on adding the menu XML file, if you need a reminder.)
