java图片自动播放代码

java：求一段代码,很简单,运行后直接播放一个小视频,播放完后（或者自行定时）立刻自动关闭.

下面是一个例子

import?java.awt.BorderLayout;

import?java.awt.Component;

import?java.net.MalformedURLException;

import?java.net.URL;

import?javax.media.Manager;

import?javax.media.MediaLocator;

import?javax.media.Player;

import?javax.swing.JFileChooser;

import?javax.swing.JFrame;

public?class?MediaPlayer?extends?javax.swing.JPanel?{

public?MediaPlayer(URL?mediauUrl)?{??

initComponents();

setLayout(new?BorderLayout());

try?{

Player?mediaPlayer?=?Manager.createRealizedPlayer(new?MediaLocator(mediauUrl));

Component?video?=?mediaPlayer.getVisualComponent();

Component?control?=?mediaPlayer.getControlPanelComponent();

if?(video?!=?null)?{

add(video,?BorderLayout.CENTER);??//?place?the?video?component?in?the?panel

}

add(control,?BorderLayout.SOUTH);??//?place?the?control?in?panel

mediaPlayer.start();

}?catch?(Exception?e)?{

private?void?initComponents()?{

javax.swing.GroupLayout?layout?=?new?javax.swing.GroupLayout(getTopLevelAncestor());

layout.setHorizontalGroup(

layout.createParallelGroup(javax.swing.GroupLayout.Alignment.LEADING)

);

layout.setVerticalGroup(

public?static?void?main(String[]?args)?{

JFileChooser?fileChooser?=?new?JFileChooser();

fileChooser.showOpenDialog(null);

URL?mediaUrl?=?null;

mediaUrl?=?fileChooser.getSelectedFile().toURI().toURL();

}?catch?(MalformedURLException?ex)?{

System.out.println(ex);

JFrame?mediaTest?=?new?JFrame("Movie?Player");

mediaTest.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

MediaPlayer?mediaPanel?=?new?MediaPlayer(mediaUrl);

mediaTest.add(mediaPanel);

mediaTest.setLocationRelativeTo(null);

mediaTest.setVisible(true);

如何用java实现图片预览功能,求代码

使用两种不同的方法实现图片预览功能

Java代码

BODY

script language="javascript"

function ShowImage(path){

function test(){

document.all.showimg.src=document.all.file1.value;

/script

input type="file" id="file1" onchange="test()"br/

/BODY

"java如何打开本地播放器后自动播放视频文件"

"执行的程序" 文件路径

//注意一：程序的路径要打引号,我的迅雷看看在f盘 ,文件在e盘.

//注意二:程序和文件夹路径中间有个空格.

根据下面的代码自己修改吧

用JAVA在界面中实现幻灯片播放,求代码

然后把改名后的照片文件放到你的项目名的目录下,比如你的项目名叫"slideshow",你就把照片文件放到slideshow文件夹下.

最后把下面的Java程序拷贝到你的项目中,把有DD类名的地方改成你的类名,就行了.

完整的让一些照片在JFrame窗体里自动随机播放的幻灯片程序如下

import java.awt.Graphics;

import javax.swing.ImageIcon;

import javax.swing.JFrame;

public class DD extends JFrame implements Runnable{

ImageIcon ii=new ImageIcon("photo1.jpg");//这里换成你的图片文件名,放在你的项目名的文件夹中

DD(){

super("Slide");

setLocationRelativeTo(null);

setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

setVisible(true);

public void paint(Graphics g){

super.paint(g);

@Override

public void run() {

while(true){

try {

} catch (InterruptedException e) {

e.printStackTrace();

this.repaint();

public static void main(String[] args) {

DD d=new DD();

Thread t=new Thread(d);

t.start();

怎么让图片在网页里自动播放

那是一个JAVA的图片切换代码,您可以在那些网页的原代码里面找到.

一般循环的图片不超过五张.当然超过是可以的只是要一行一行去写,比较麻烦.代码就不帖了,如果没有从网站里面拷贝出来,也可以加我的QQ来找我.
