如何用java實現(xiàn)圖片預覽功能，求代碼

使用兩種不同的方法實現(xiàn)圖片預覽功能

Java代碼

BODY

script language="javascript"

function ShowImage(path){

document.all.divShow.filters.item("DXImageTransform.Microsoft.AlphaImageLoader").src = path;

}

function test(){

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

}

/script

INPUT style="Z-INDEX: 101; LEFT: 232px; POSITION: absolute; TOP: 272px" type="file"onchange="ShowImage(this.value)"

div id="divShow" style="FILTER:progid:DXImageTransform.Microsoft.AlphaImageLoader(sizingMethod=image);WIDTH:274px;HEIGHT:100px"

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

img id="showimg" style="width:200px;height:200px;"

"java如何打開本地播放器后自動播放視頻文件"

“執(zhí)行的程序” 文件路徑

//注意一：程序的路徑要打引號，我的迅雷看看在f盤 ，文件在e盤。

//注意二:程序和文件夾路徑中間有個空格.

根據(jù)下面的代碼自己修改吧

Runtime.getRuntime().exec("\"f:\\Program?Files?(x86)\\Thunder?Network\\Xmp\\Program\\XMP.exe\"?e:\\mp4\\high歌.mp4");

用JAVA在界面中實現(xiàn)幻燈片播放，求代碼

要讓照片隨機播放,需要把照片名改成比如photo1.jpg,photo2.jpg,photo3.jpg...的有序號順序排列的文件名,

然后把改名后的照片文件放到你的項目名的目錄下,比如你的項目名叫"slideshow",你就把照片文件放到slideshow文件夾下.

最后把下面的Java程序拷貝到你的項目中,把有DD類名的地方改成你的類名,就行了.

完整的讓一些照片在JFrame窗體里自動隨機播放的幻燈片程序如下

(我用的圖片文件是photo1.jpg,photo2.jpg,photo3.jpg,注意事項在注釋中注明

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");//這里換成你的圖片文件名,放在你的項目名的文件夾中

DD(){

super("Slide");

setSize(400, 400);

setLocationRelativeTo(null);

setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

setVisible(true);

}

public void paint(Graphics g){

super.paint(g);

g.drawImage(ii.getImage(),0,0,400,400,null);

}

@Override

public void run() {

while(true){

try {

Thread.sleep(500);//這里是幻燈片播放間隔的時間,這里為500毫秒=0.5秒

} catch (InterruptedException e) {

e.printStackTrace();

}

int i=(int)(Math.random()*3)+1;//這里是產(chǎn)生從1-3的隨機數(shù),如果你有6個圖片文件,把3改成6就是從1-6的隨機數(shù)了.

ii=new ImageIcon("photo"+i+".jpg");//這里調用你的圖片文件,如果你有6個圖片文件,改成從1-6的文件名方便調用

this.repaint();

}

}

public static void main(String[] args) {

DD d=new DD();

Thread t=new Thread(d);

t.start();

}

}

怎么讓圖片在網(wǎng)頁里自動播放

那是一個JAVA的圖片切換代碼，您可以在那些網(wǎng)頁的原代碼里面找到。

一般循環(huán)的圖片不超過五張。當然超過是可以的只是要一行一行去寫，比較麻煩。代碼就不帖了，如果沒有從網(wǎng)站里面拷貝出來，也可以加我的QQ來找我。
