When using surfaceview, you will find that the ondraw (canvas) method of the parent class is not executed. The reason is that in surfaceview, we do not directly deal with it, but control it through surfaceholder. Use the lockcanvas () function of surfaceholder to obtain the canvas object of surfaceview, and modify the data in surfaceview by drawing the content on the canvas. Public class mysurfaceview extends surfaceview implements callback, runnable {private surfaceholder SFH; private paint;
