Images and Audio in an Alert Dialog

I'm using the following tutorial http://developer.android.com/resources/tutorials/views/hello-mapview.html in order to create a map view and plot points on to it. I have all of that done fine but now I'd like to embed开发者_StackOverflow社区 an image and even audio within the Alert dialogs that pop up. Is this possible in the current context? How would I do it?

You need to create a Custom Dialog.
