怎么用java做动画

重写paint方法，来实现将自己定义的图片绘制到组件中，然后启动一个线程来控制paint方法。 示例： ××××××××××××××××××××××××××× import javax.swing.*; import java.awt.*;class MyPanel extends JPanel implements Runnable {private Image img;private int i=0;private int j=0;public MyPanel(){img=new ImageIcon("1.png").getImage();}public void paint(Graphics g){g.drawImage(img,0,0,60,104,i*60,j*104,i*60+60,j*104+104,this);}public void run(){while(true){while(j {while(i {try{Thread.sleep(300);}catch(Exception e){}this.repaint();i++;}j++;i=0;}i=0;j=0;}} }public class test extends JFrame {private MyPanel p;public test(){p=new MyPanel();this.add(p,BorderLayout.CENTER);this.setBounds(300,200,300,300);this.setTitle("人物行走图");new Thread(p).start();this.setVisible(true);this.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);}public static void main(String args[]){new test();} }××××××××××××××××××××××× 将以上源码保存为：test.java，编译，然后下载下面的图片 将下载的图片改名为1.png" target="_blank"

,然后将其和编译后生成的class文件放在同一文件夹下，然后运行就可以了·～～

Java编程实现一个能循环地自左向右移动的动画程序。

效果图

参考代码

import java.awt.*;

import java.awt.event.*;

import javax.swing.*;

public class MoveTextFrame extends JFrame {

JLabel jl;//文字标签

int speed=2;//移动速度

public MoveTextFrame() {

jl = new JLabel("文字动画");

jl.setForeground(Color.RED);

add(jl);

setSize(380, 100);//窗口大小

setLocationRelativeTo(null);//窗口居中

setResizable(false);

setDefaultCloseOperation(EXIT_ON_CLOSE);

setVisible(true);

//设置定时器, 每隔25毫秒,改变一次文字标签的位置

Timer t = new Timer(25, new ActionListener() {

public void actionPerformed(ActionEvent e) {

int x = jl.getX()+speed;//计算移动后的位置

if(x=390){//如果超过就指定像素,就重新从左边开水移动

x=-30;

}

jl.setLocation(x, jl.getY());//更新位置

//repaint();

}

});

t.start();

}

public static void main(String[] args) {

new MoveTextFrame();
