I'm trying to do this in such a way that I don't have to replicate code...what ideally I would like is when I press either of the rotate buttons, it invalidates the image causing it to be re-rendered and rotated, so far the only way I've been able to get the rotation to work is to get the imageview in my event listener, rotate the bitmap then put it back in the imageview.
I like to understand what is happening behind the scenes and I must admit I'm not quite sure what methods are available to me, I'll take a look at the links provided by Mark. Thank you.
