图片移动java代码 java图片滚动

IT技术图片

java如何实现图片拖动，放大缩?。?。这个只是实现图片移动java代码了移动图片移动java代码，图片移动java代码你参考以下吧 图片移动java代码！
public class MoveImage {
static int x,y;
private static int num=0;
private static Icon icon=null;
public static void main(String[] args) throws Exception{
JFrame f = new JFrame();
f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
f.getContentPane().setLayout(null);//这个要设置成 null
//图片
icon = new ImageIcon("d:/test.gif");//d:/test.gif本地一张图片
JLabel l = new JLabel(icon); //创建具有指定图像图片移动java代码的 JLabel 实例 。
l.setSize(icon.getIconWidth(),icon.getIconHeight());//设置面板的宽度和高度
l.setBorder(BorderFactory.createLineBorder(Color.red));//给图片加上红色外框
f.getContentPane().add(l);
f.setSize(900,700);
f.setVisible(true);
l.addMouseListener(new MouseAdapter(){
public void mousePressed(MouseEvent e){
x=e.getX();
y=e.getY();
}
});
l.addMouseMotionListener(new MouseMotionListener(){
public void mouseDragged(MouseEvent e) {
JLabel l = (JLabel)e.getSource();
l.setLocation(l.getX() e.getX()-x,l.getY() e.getY()-y);
}
public void mouseMoved(MouseEvent e) {}
});
}
java语言里怎么让图象移动到指定位置啊,最好用一小段代码说明.改变规制时候图片移动java代码的X Y就行图片移动java代码了.伪代码如下.
int x =0,y=0,;
x; y;
g.drawImage( "图片信息" , x, y,锚点);
大概就这样图片就动图片移动java代码了.图片移动java代码你想移动到哪加个判断就行图片移动java代码了.
在Java怎么让图片水平移动？java让图片水平移动图片移动java代码，就是不断监听图片的位置图片移动java代码，示例如下图片移动java代码：
//给个实例
import java.awt.Color;
import java.awt.event.MouseAdapter;
import java.awt.event.MouseEvent;
import java.awt.event.MouseMotionListener;
import java.net.URL;
import javax.swing.BorderFactory;
import javax.swing.Icon;
import javax.swing.ImageIcon;
import javax.swing.JFrame;
import javax.swing.JLabel;
public class ImageMove {
static int x,y;
public static void main(String[] args) throws Exception{
JFrame f = new JFrame();
f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
f.getContentPane().setLayout(null);//这个要设置成 null
//图标
Icon icon = new ImageIcon(new URL(""));
// Icon icon = new ImageIcon("c:/logo-zhidao.gif");//本地图片文件
JLabel l = new JLabel(icon);
l.setSize(icon.getIconWidth(),icon.getIconHeight()); l.setBorder(BorderFactory.createLineBorder(Color.red));
f.getContentPane().add(l); f.setVisible(true);
l.addMouseListener(
new MouseAdapter(){
public void mousePressed(MouseEvent e){ x=e.getX();y=e.getY(); } });
l.addMouseMotionListener(new MouseMotionListener(){ public void mouseDragged(MouseEvent e) { JLabel l = (JLabel)e.getSource();
l.setLocation(l.getX() e.getX()-x,l.getY() e.getY()-y);
}
public void mouseMoved(MouseEvent e) {} }); } }
java 中移动图片，并且在按键盘的“回车”时 ， 切换到另外一张图片?。∏朐谖蚁旅娴拇敫慕 。。⌒恍唬 。?/h2>你好 ， 按照你的要求代码如下，修改了三处
简单说明一下，就是加了一个标识boolean，用true/false来表示显示第一张/第二张图片
import java.awt.*;
import java.awt.event.*;
import java.awt.event.KeyEvent;
import java.awt.event.KeyListener;
import javax.swing.*;
public class zhandou extends JFrame implements KeyListener {
Image roleImage, Image1;
int x, y;
public zhandou() {
super("MOVE");
Container c = getContentPane();
setSize(320, 240);
setVisible(true);
loadImage();
setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
// setFocusable(true);
addKeyListener(this);
}
boolean key = true;// 加这样一个标识 ， true是第一张图片，false为第二张图片
public void paint(Graphics g) {
super.paint(g);
// drawRole(g);
if (key) {// 根据标识判断需要显示的图片
g.drawImage(roleImage, x, y, this);
} else {
g.drawImage(Image1, x, y, this);
}
}
public void loadImage() {
ImageIcon icon = new ImageIcon("tupian/草地.jpg");
roleImage = icon.getImage();
ImageIcon ic = new ImageIcon("tupian/right.gif");
Image1 = ic.getImage();
}
class Thread1 extends Thread {
}
/*
* private void drawRole(Graphics g) { g.drawImage(roleImage,100,100,this);
* }
*/
public void keyPressed(KeyEvent e) {
if (e.getKeyCode() == KeyEvent.VK_UP)
y = y - 5;
else if (e.getKeyCode() == KeyEvent.VK_DOWN)
y = y5;
else if (e.getKeyCode() == KeyEvent.VK_RIGHT)
x = x5;
else if (e.getKeyCode() == KeyEvent.VK_LEFT)
x = x - 5;
else if (e.getKeyCode() == KeyEvent.VK_ENTER)
key = !key;// 切换标识状态
repaint();
}
public void keyReleased(KeyEvent e) {
}
public void keyTyped(KeyEvent e) {
}
public static void main(String args[]) {
new zhandou();
}
}
怎么编写java程序实现图片的移动(最好有例子)import java.awt.Color;
import java.awt.Graphics;
import java.awt.Image;
import java.awt.event.KeyAdapter;
import java.awt.event.KeyEvent;
import javax.swing.JFrame;
public class DrawTest extends JFrame {
private int x = 50;
private int y = 50;
private Image offScreenImage = null;
@Override
public void paint(Graphics g) {
Color c = g.getColor();
g.setColor(Color.BLACK);
g.fillOval(x, y, 30, 30);
g.setColor(c);
}
public void update(Graphics g) {
if (offScreenImage == null) {
offScreenImage = this.createImage(500, 500);
}
Graphics gOffScreen = offScreenImage.getGraphics();
Color c = gOffScreen.getColor();
gOffScreen.setColor(Color.GREEN);
gOffScreen.fillRect(0, 0, 500, 500);
gOffScreen.setColor(c);
paint(gOffScreen);
g.drawImage(offScreenImage, 0, 0, null);
}
public static void main(String[] args) {
DrawTest d = new DrawTest();
}
public DrawTest() {
init();
addKeyListener(new KeyAdapter() {
public void keyPressed(final KeyEvent e) {
int code = e.getKeyCode();
switch (code) {
case KeyEvent.VK_UP:
y -= 5;
break;
case KeyEvent.VK_RIGHT:
x= 5;
break;
case KeyEvent.VK_DOWN:
y= 5;
break;
case KeyEvent.VK_LEFT:
x -= 5;
break;
}
}
});
}
public void init() {
this.setDefaultCloseOperation(this.EXIT_ON_CLOSE);
this.setBackground(Color.GREEN);
this.setResizable(false);
this.setBounds(140, 140, 500, 500);
this.setVisible(true);
MyThread mt = new MyThread();
new Thread(mt).start();
}
class MyThread implements Runnable {
public void run() {
while (true) {
repaint();
try {
Thread.sleep(100);
} catch (InterruptedException e) {
e.printStackTrace();
}
}
}
}
}
