Hi, If you were using SurfaceView's onDraw() method then you were not getting any benefit. You have to use lockCanvas()/unlockCanvasAndPost() and post on the underlying Surface. TextureView works in a similar way: you can call lockCanvas()/unlockCanvasAndPost().
However, it seems all you need is a View. It's easier to use and since you are not using SurfaceView properly anyway it will do the same thing.
