怎么用java做動(dòng)畫

重寫paint方法，來實(shí)現(xiàn)將自己定義的圖片繪制到組件中，然后啟動(dòng)一個(gè)線程來控制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("人物行走圖");new Thread(p).start();this.setVisible(true);this.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);}public static void main(String args[]){new test();} }××××××××××××××××××××××× 將以上源碼保存為：test.java，編譯，然后下載下面的圖片 將下載的圖片改名為1.png" target="_blank"

在昌黎等地區(qū)，都構(gòu)建了全面的區(qū)域性戰(zhàn)略布局，加強(qiáng)發(fā)展的系統(tǒng)性、市場前瞻性、產(chǎn)品創(chuàng)新能力，以專注、極致的服務(wù)理念，為客戶提供做網(wǎng)站、網(wǎng)站建設(shè) 網(wǎng)站設(shè)計(jì)制作按需定制開發(fā),公司網(wǎng)站建設(shè),企業(yè)網(wǎng)站建設(shè),高端網(wǎng)站設(shè)計(jì),成都營銷網(wǎng)站建設(shè),外貿(mào)營銷網(wǎng)站建設(shè),昌黎網(wǎng)站建設(shè)費(fèi)用合理。

,然后將其和編譯后生成的class文件放在同一文件夾下，然后運(yùn)行就可以了·～～

2.Java有哪幾種常見的實(shí)現(xiàn)動(dòng)畫的方法?

一: 用多線程播放一組圖片, 實(shí)現(xiàn)動(dòng)畫片的效果; 類似于逐幀動(dòng)畫,每個(gè)圖片是動(dòng)畫的一幀

二: 在awt/swing界面里, 可以使用paint方法,去繪制圖形,然后用swing提供的Timer或者多線程技術(shù),去刷新繪制的圖形

三:在JavaFX里, 本身就支持動(dòng)畫,并且封裝了很多動(dòng)畫效果可以直接使用,比如逐幀動(dòng)畫.縮放動(dòng)畫,漸變動(dòng)畫,旋轉(zhuǎn)動(dòng)畫,位置動(dòng)畫等.

強(qiáng)烈推薦使用javaFX來實(shí)現(xiàn)動(dòng)畫, 因?yàn)閖avaFX是現(xiàn)代化的圖形界面工具,具有簡單,強(qiáng)大,組件豐富,跨平臺(tái),支持Html5, 支持表格, 支持動(dòng)畫等多種優(yōu)勢?
