[英]How to use animated gif file as a splash screen in java?
我正在使用Java 1.5,希望在启动应用程序之前显示动画,并在加载应用程序时关闭它。 我在Google搜索后创建了一些东西,但是如果我使用的不是动画gif,则动画gif不会动画。
请问有人有什么问题,知道怎么做吗?
public class SplashFrameSwing extends JFrame{
JPanel contentPane;
JLabel imageLabel = new JLabel();
public SplashFrameSwing(String url) throws IOException {
try {
ImageIcon ii = new ImageIcon(url);
setBackground(new Color(0, 0, 0, 0));
setDefaultCloseOperation(DO_NOTHING_ON_CLOSE);
contentPane = (JPanel) getContentPane();
contentPane.setLayout(new BorderLayout());
setUndecorated(true);
setSize(new Dimension(ii.getIconWidth(),ii.getIconHeight()));
imageLabel.setIcon(ii);
contentPane.add(imageLabel, java.awt.BorderLayout.CENTER);
this.setLocationRelativeTo(null);
this.setVisible(true);
} catch (Exception exception) {
exception.printStackTrace();
}
}
public static void main(String... args){
SwingUtilities.invokeLater(new Runnable() {
public void run() {
try {
// URL url = new URL("http://i34.photobucket.com/albums/d129/nirendaran/Speed/verify_anim.gif");
String url = "C:\\Users\\TV\\Pictures\\Icon\\sniffer-prev.gif";
SplashFrameSwing splash = new SplashFrameSwing(url);
} catch (IOException e) {
e.printStackTrace();
}
}
});
}
}
这对我有效,但是我正在使用1.7.0_05版本。
EventQueue.invokeLater(new Runnable(){
public void run(){
JLabel label = new JLabel();
label.setHorizontalAlignment(SwingConstants.CENTER);
try{
// URL imageURL = new URL("http://static.ak.fbcdn.net/rsrc.php/v2/yb/r/GsNJNwuI-UM.gif");
URL imageURL = new URL("http://i34.photobucket.com/albums/d129/nirendaran/Speed/verify_anim.gif");
label.setIcon(new ImageIcon(imageURL));
}
catch (MalformedURLException ex){
ex.printStackTrace();
}
JFrame frame = new JFrame();
frame.add(label, BorderLayout.CENTER);
frame.setDefaultCloseOperation(WindowConstants.DISPOSE_ON_CLOSE);
frame.setMinimumSize(new Dimension(160, 120));
frame.setVisible(true);
}
});
