请告诉我如何绘制整个动画的简单方法?！"

这可能与您在图像中的阅读方式有关.如果您使用 ImageIO.read，它将不起作用.如果您将其作为 ImageIcon 阅读，它似乎可以工作

It may have to to do with how you're reading in the image. If you use ImageIO.read, it won't work. If you read it as an ImageIcon it seems to work

ImageIcon.getImage()

Image icon = new ImageIcon(new URL("http://i.stack.imgur.com/KSnus.gif")).getImage();
...
g.drawImage(icon, 20, 20, this);

带有 ImageIO 的图像

Image icon = ImageIO.read(new URL("http://i.stack.imgur.com/KSnus.gif"));
...
g.drawImage(icon, 20, 20, this);
