Go to the bottom of the new UI definition, and add a container structure, right above
the closing container closing tag, and add an tag inside it, as
is shown in Figure 8-20.

Since the UI widget needs a digital image to use for its “source” or android:src
parameter, let’s copy the three galaxy images, named galaxybutton1.png, galaxybutton2.png, and
galaxybutton3.png into the /res folder using the Windows Explorer file management utility next.

As you can see in Figure 8-21, I have copied these files, which are in the project files repository for
the book, into the /res/drawable-hdpi folder.
