我得到了用Java创建启动画面和线程管理的源代码。但我不知道如何实现它。如何实现启动画面Java
public class SplashWindow extends JWindow {
public SplashWindow(String filename, Frame f, int waitTime)
{
super(f);
JLabel l = new JLabel(new ImageIcon(filename));
getContentPane().add(l, BorderLayout.CENTER);
pack();
Dimension screenSize =
Toolkit.getDefaultToolkit().getScreenSize();
Dimension labelSize = l.getPreferredSize();
setLocation(screenSize.width/2 - (labelSize.width/2),
screenSize.height/2 - (labelSize.height/2));
addMouseListener(new MouseAdapter()
{
public void mousePressed(MouseEvent e)
{
setVisible(false);
dispose();
}
});
final int pause = waitTime;
final Runnable closerRunner = new Runnable()
{
public void run()
{
setVisible(false);
dispose();
}
};
Runnable waitRunner = new Runnable()
{
public void run()
{
try
{
Thread.sleep(pause);
SwingUtilities.invokeAndWait(closerRunner);
}
catch(Exception e)
{
e.printStackTrace();
// can catch InvocationTargetException
// can catch InterruptedException
}
}
};
setVisible(true);
Thread splashThread = new Thread(waitRunner, "SplashThread");
splashThread.start();
}
}
我尝试实施这样的: ... 公共静态无效的主要(字串[] args){ 的JFrame帧=新的JFrame(); frame.setSize(500,500);
SplashWindow window = new SplashWindow("splash-scren.jpg", frame, 1000);
}
...
但没有显示。 请帮帮我,谢谢:)
不要推倒重来; Java已经有了[启动画面]的内置实现(http://docs.oracle.com/javase/tutorial/uiswing/misc/splashscreen.html)。注意:此启动画面在* JVM启动之前显示*。之后,您可以使用['SplashScreen'](http://docs.oracle.com/javase/7/docs/api/java/awt/SplashScreen.html)类更改图像/ etc。 – Jeffrey
