java动态图片界面代码 java动态相册

java中在窗体的创建一个面板中加入一个gif动态图

你是说 JPanel 吗？两种方法：

添加 JLabel，给 JLabel 添加 ImageIcon，然后放置 JLabel 到 JPanel 上就行了：

JPanel pnl = new JPanel();

......

JLabel lblImage = new JLabel(new ImageIcon("你的文件名")); //创建一个带图片的 JLabel

lblImage.setBounds(0, 0, pnl.getWidth(), pnl.getHeight()); //设置 图片的横坐标、纵坐标、宽、高

pnl.add(lblImage); //放置这个 JLabel 到你的 JPanel 上面

还有一种方法是重写 JPanel 的 paint() 方法：

class YourPanel extends JPanel {

private Image img = Toolkit.getDefaultToolkit().createImage("你的文件名"); //用 Toolkit 的 createImage 方法来创建一个 Image 对象

@Override public void paint (Graphics g) {

super.paint(g);

g.drawImage(img, 0, 0, getWidth(), getHeight()); //绘制图片，第一个参数是 Image 对象，第二个参数是 横坐标，第三个是 纵坐标，第四个是 宽，第五个是 高

}

}

以上你隐式重写也可以：

JPanel pnl = new JPanel() {

@Override public void paint (Graphics g) {

...... //但是要注意这样如果你把 Image 声明成了局部变量或者参数形式，你需要声明成 final

}

}

java 如何生成动态的gif图片

实现思路java动态图片界面代码：无论是何种类型java动态图片界面代码，都是转换为流的形式进行的文件传输和存储。

可以通过BufferedReader 流的形式进行流缓存，之后通过readLine方法获取到缓存的内容。

BufferedReader bre = null;

OutputStreamWriter pw = null;//定义一个流

try {

String file = "D:/test/test.GIF";

bre = new BufferedReader(new FileReader(file));//此时获取到的bre就是整个文件的缓存流

pw = new OutputStreamWriter(new FileOutputStream(“D:/New.GIF”),"GBK");//确认流的输出文件和编码格式，此过程创建了“test.GIF”实例

while ((str = bre.readLine())!= null) // 判断最后一行不存在，为空结束循环

{

pw.write(str);//将要写入文件的内容，可以多次write

}；

bre.close()；

pw.close();//关闭流

备注：文件流用完之后必须及时通过close方法关闭，否则会一直处于打开状态，直至程序停止，增加系统负担。

java图形化界面中如果我要设置四个按钮，然后摁每个按钮可以切换不同的图片，谁能帮我做一下代码给我参考

参考代码,

注意图片的路径,拿不准的话,就使用绝对路径吧

import java.awt.*;

import java.awt.event.*;

import javax.swing.*;

//我的图片路径是 src\\images\\1.gif  .有四张 从1.jpg~~4.jpg

public class ImageDemo extends JFrame {

JLabel jl;

JPanel jp;

public ImageDemo() {

jp = new JPanel();

int i;

for (i = 0; i  4; i++) {

if(i ==0){//初始化的时候,默认显示的图片

jl = new JLabel(new ImageIcon("src\\images\\"+1+".gif"));

}

//按钮

JButton jb = new JButton("第"+(i+1)+"张图");

int z = i;

//当按钮点击的时候

jb.addActionListener(new ActionListener() {

@Override

public void actionPerformed(ActionEvent e) {

//设置jl的图片

jl.setIcon(new ImageIcon("src\\images\\"+(z+1)+".gif"));

}

});

jp.add(jb);

}

this.setLocation(200, 120);

this.setSize(500,200);

this.setLayout(new BorderLayout());

this.add(jl);

this.add(jp,BorderLayout.SOUTH);

this.setTitle("图片浏览");

this.setDefaultCloseOperation(EXIT_ON_CLOSE);

this.setVisible(true);

}

public static void main(String[] args) {

new ImageDemo();

}

}

用java语言写的动态屏保

美当然很复杂，如果只是简单实现，还是比较容易的。

我大概的思路就是有一个表，这个表是固定的内容，例如有列：表名，字段名，字段类型，PAGE TITLE等。根据需要可以增加一些其它的内容。

其它的表根据这个表里的数据来创建新表和alter字段就可以了。页面呈现部分也可以根据这里的设置来进行拼装。

当然这些内容都是可以配置进配置文件，也可以为每一种类型创建相应的类，通过数据库，或者配置文件的配置，通过反射机制来加载。

根据这个思路，如果抽象的好完全可以在后期动态创建页面，动态创建空间。只需要有一个配置界面去更新数据库里固定的那张表或配置文件的节点就好了。

具体问题具体分析，如果配置项少，完全可以在启动的时候将所有信息一次性加载进内存，这样在绘制界面的时候不用每次都去查询数据库或文件。关键还是看你需要动态到什么地步。但无论如何总应该有一个地方去存储这些动态生成的东西的结构，就像数据库自身的实现一样，它总是有些系统表存储这些用户定义的信息，你也可以考虑利用系统表来干这件事。
