I have created an app with coverflow. I have looked everywhere and can't seem to work out how to use an onclicklistener to get to just a simple activity when you click on each seperate image in the cover flow. Below is my code and i'm hoping somebody can help because the app is all good to go apart from this 1 problem!!
