MyView needs to inherit the View and implement the onDraw (Canvas canvas) method in it. Canvas is equivalent to a blank sheet of white paper, while painting is the pen of the painting tool, these two classes can be used to achieve good graphics in the game.
Call the invalidate () method to redraw it, that is, call the onDraw () method once. If it is called in other classes, you must call postInvalidate.
