原理很简单，用Gif图片的连续几帧图片，在JPanel中画出来，显示出动态图效果

package multi_media;import java.awt.Graphics;import java.awt.Image;import java.io.File;import java.net.URI;import java.util.ArrayList;import java.util.List;import javax.imageio.ImageIO;import javax.swing.JFrame;import javax.swing.JPanel;public class MyDraw extends JPanel{/** *  */private static final long serialVersionUID = 1L;private int curPic;private int allPic;private int picHeight;private int picWidth;private List<Image> images;public MyDraw() {try{final URI dir = getClass().getResource(".").toURI();String [] files = new File(dir).list();images = new ArrayList<Image>();for(String file : files) {if(file.toLowerCase().endsWith(".gif")) {Image i = ImageIO.read(new File(new File(dir), file));images.add(i);if(picHeight == 0 || picWidth == 0) {picHeight = i.getHeight(this);picWidth = i.getWidth(this);}}}allPic = images.size();}catch(Exception e) {e.printStackTrace();}}@Overrideprotected void paintComponent(Graphics g) {// TODO Auto-generated method stubsuper.paintComponent(g);if(images == null || images.size() == 0) {return ;}//System.out.println(allPic);g.drawImage(images.get(curPic), 0, 0, this);curPic++;if(curPic == allPic)curPic = 0;}public static void main(String[] args) {JFrame f = new JFrame();MyDraw d = new MyDraw();f.add(d);f.setSize(d.picWidth, d.picHeight);f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);f.setVisible(true);while(true) {try {Thread.sleep(100);} catch (InterruptedException e) {// TODO Auto-generated catch blocke.printStackTrace();}d.repaint();}}}
