总是觉得Java Swing没有Android的好,不能自定义组件,实现漂亮的进度提示框,比如那种转圈的,谷歌了一下竟然发现有大牛实现了类似的额效果:
使用方法:
1.具体只需要两个类:AnimatedPanel.java, InfiniteProgressPanel.java,具体的内容如下:
AnimatedPanel.java的代码如下:
package com.jframe.ceshi;
/*
* Created on 25 juin 2004
* AnimatedPanel.java
* Panneau anim茅.
*/
import java.awt.AlphaComposite;
import java.awt.Color;
import java.awt.Font;
import java.awt.Graphics;
import java.awt.Graphics2D;
import java.awt.Image;
import java.awt.RenderingHints;
import java.awt.font.FontRenderContext;
import java.awt.font.TextLayout;
import java.awt.geom.Rectangle2D;
import java.awt.image.BufferedImage;
import java.awt.image.BufferedImageOp;
import java.awt.image.ConvolveOp;
import java.awt.image.Kernel;
import javax.swing.ImageIcon;
import javax.swing.JPanel;
/**
* Affiche un panneau anim茅. L'animation consiste en l'highlight d'une image.
*
* @author Romain Guy
*/
public
class AnimatedPanel extends JPanel {
/**
*
*/
private
static
final
long serialVersionUID =
1L;
private
float gradient;
private String message;
private Thread animator;
private BufferedImage convolvedImage;
private BufferedImage originalImage;
private Font font;
private
static AlphaComposite composite = AlphaComposite.getInstance(AlphaComposite.SRC_OVER);
/**

* ne d茅marre que par un appel 脿 start().
*
* @param message Le message 脿 afficher

* @author Romain Guy
*/
public AnimatedPanel(String message, ImageIcon icon) {
this.message = message;
this.font = getFont().deriveFont(
14.0f);
Image image = icon.getImage();
originalImage =
new BufferedImage(icon.getIconWidth(), icon.getIconHeight(), BufferedImage.TYPE_INT_ARGB);
convolvedImage =
new BufferedImage(icon.getIconWidth(), icon.getIconHeight(), BufferedImage.TYPE_INT_ARGB);
Graphics g = originalImage.createGraphics();
g.drawImage(image,
0,
0,
this);

1.0f);
setOpaque(
false);
}
@Override
public void paintComponent(Graphics g) {
super.paintComponent(g);
if (convolvedImage !=

2;
int y = (
int) (height - (convolvedImage.getHeight(
null) + bounds.getHeight() + layout.getAscent())) /
2;
g2.drawImage(convolvedImage, x, y,
this);
g2.setColor(
new Color(
0,
0,
0, (
int) (gradient *
255)));
layout.draw(g2, (
float) (width - bounds.getWidth()) /
2,
(
float) (y + convolvedImage.getHeight(
null) + bounds.getHeight() + layout.getAscent()));
}
}
}
/**

*

*/

repaint();
}
/**

*/
private void setGradientFactor(float gradient) {
this.gradient = gradient;
}

*/
public void start() {

this.animator.start();
}
/**

*/
public void stop() {

}
this.animator =
null;
}

*/

3.如何在你的Java Swing使用呢,如下步骤:
JFrame frame = new JFrame(); // ... InfiniteProgressPanel glasspane = new InfiniteProgressPanel();
Dimension dimension = Toolkit.getDefaultToolkit().getScreenSize(); glasspane.setBounds(100, 100, (dimension.width) / 2, (dimension.height) / 2); frame.setGlassPane(glasspane); glasspane.start();//开始动画加载效果 frame.setVisible(true); // Later, to disable,在合适的地方关闭动画效果 glasspane.stop();
