Android - Canvas that (virtually) extends off the end of the phone

I have seen many iPhone and开发者_运维百科 iPad note apps where there is a drawing canvas, and if you use 2 fingers and drag, the canvas itself moves, like it is endless. They can go to a different part of the canvas, but still be on the same note/page.

I was wondering if this is possible on Android, and if there are any tutorials out there?

I don't want it to be endless, but extend more than just the single part of the screen.
