这个问题在这里已有答案:
我得到了这个用于在Java中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 .
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();
}
}
我尝试这样实现:... public static void main(String [] args){JFrame frame = new JFrame(); frame.setSize(500,500);
SplashWindow window = new SplashWindow("splash-scren.jpg", frame, 1000);
}
...
但没有任何表现 . 请帮帮我,谢谢:)
