I want pan and zoom functionality (like a MapView) on my own map image

Question

How can I get my own image to be able to pan and zoom (like a MapView)?

Answer 1

I tried hosting an image in a WebView (built-in pan and zoom), but there were a number of problems. I ended up extending the View class and overriding onDraw. It was not hard, once I finally decided to use that method.
