Canvas with image underneath

I want to make a canvas with an image underneath, like for tracing. I set up an image and surface view in XML and it looks fine but when I run the program, I can't see the image underneath. I've played with the canvas alpha level and nothing seems to work.

I know this can be done because I've done it with MIT's app inventor but want to program with Java.

(I'd love to see a graphical drawing program as a tutorial!)

It sounds like you're trying to make the SurfaceView transparent...if that's the case, this StackOverflow answer might help: http://stackoverflow.com/a/7061396/475217
