There is nothing in that example that says you have to be using a canvas. Any view that is a child of View will work. GLSurfaceView is a child of view and will work also.
Override the onTouchEvent of the GLSurfaceView and follow the example in that respect. The scaling is just a number that goes up when they get farther apart and lower as they get closer. If you aren't able to use this number, then you won't be able to use multi-touch pinch-to-zoom functionality. There is even a function that calculates the mid point for you (getFocusX, getFocusY), it doesn't get much simpler than that. Some things you just have to work through because that's how they are done. Refusing to use advice (especially from the creators of Android who would know best) won't help you figure out how to use the feature any faster.
