Simple App Question

**skylab** · 08-13-2012, 08:27 AM

I have this code below. It is for an android app. What it does now is, it uses a slider similar to the picture attached. What I want is to modify the code below so that it can play the appropriate audio for each page not only the audio called cat.mp3. Because now, whenever I slide to the next image and click on it, I still here the audio of the cat, not the dog or cow. Any help would be greatly appreciated.

Image of the app: View image: prototype
