如何在 Java 应用程序中显示动画 GIF?
11 回答
使用Swing,您可以简单地使用JLabel
:
public static void main(String[] args) throws MalformedURLException {
URL url = new URL("<url_to_animated_gif>");
Icon icon = new ImageIcon(url);
JLabel label = new JLabel(icon);
JFrame f = new JFrame("Animation");
f.getContentPane().add(label);
f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
f.pack();
f.setLocationRelativeTo(null);
f.setVisible(true);
}
对于加载存储在源包中(在源代码中)的动画 gif,这对我有用:
URL url = MyClass.class.getResource("/res/images/animated.gif");
ImageIcon imageIcon = new ImageIcon(url);
JLabel label = new JLabel(imageIcon);
这对我有用!
public void showLoader(){
URL url = this.getClass().getResource("images/ajax-loader.gif");
Icon icon = new ImageIcon(url);
JLabel label = new JLabel(icon);
frameLoader.setUndecorated(true);
frameLoader.getContentPane().add(label);
frameLoader.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frameLoader.pack();
frameLoader.setLocationRelativeTo(null);
frameLoader.setVisible(true);
}
我来这里是为了寻找相同的答案,但根据最热门的答案,我想出了一个更简单的代码。希望这将有助于未来的搜索。
Icon icon = new ImageIcon("src/path.gif");
try {
mainframe.setContentPane(new JLabel(icon));
} catch (Exception e) {
}
快速简单的代码:
Icon icon = new ImageIcon("src/image.gif");
JLabel label = new JLabel();
label.setIcon(icon);
不要忘记让 JFrame 可见并调整大小。
//Class Name
public class ClassName {
//Make it runnable
public static void main(String args[]) throws MalformedURLException{
//Get the URL
URL img = this.getClass().getResource("src/Name.gif");
//Make it to a Icon
Icon icon = new ImageIcon(img);
//Make a new JLabel that shows "icon"
JLabel Gif = new JLabel(icon);
//Make a new Window
JFrame main = new JFrame("gif");
//adds the JLabel to the Window
main.getContentPane().add(Gif);
//Shows where and how big the Window is
main.setBounds(x, y, H, W);
//set the Default Close Operation to Exit everything on Close
main.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
//Open the Window
main.setVisible(true);
}
}
JLabel mainLabel = new JLabel();
FileChooser chooser = new FileChooser();
chooser.setFileSelectionMode(JFileChooser.FILES_ONLY);
chooser.setMultiSelectionEnabled(false);
FileNameExtensionFilter filter = new FileNameExtensionFilter("Image", "png", "jpg", "gif");
chooser.setFileFilter(filter);
chooser.setDialogTitle(Lang.T("Open Image") + "...");
int returnVal = chooser.showOpenDialog(getParent());
if (returnVal == JFileChooser.APPROVE_OPTION) {
URL url;
try {
url = new URL("file:" + chooser.getSelectedFile().getPath());
} catch (Exception e) {
url = null;
}
Icon icon = new ImageIcon(url);
mainLabel.setIcon(icon);
}
使用“文件:”作为 URL
我想将 .gif 文件放在 GUI 中,但与其他元素一起显示。并且 .gif 文件将从 java 项目中获取,而不是从 URL 中获取。
1 - 界面顶部是一个元素列表,我们可以从中选择一个
2 - 中心将是动画 GIF
3 - 底部将显示从列表中选择的元素
这是我的代码(我需要 2 个 java 文件,第一个(Interf.java)调用第二个(Display.java)):
1 - 接口.java
public class Interface_for {
public static void main(String[] args) {
Display Fr = new Display();
}
}
2 - 显示.java
INFOS:请务必在您的 java 项目中创建一个新的源文件夹(NEW > 源文件夹)并将 .gif 放入其中,以便将其视为文件。
我得到了带有下面代码的 gif 文件,所以我可以将它导出到一个 jar 项目中(然后它是动画的)。
URL url = getClass().getClassLoader().getResource("fire.gif");
public class Display extends JFrame {
private JPanel container = new JPanel();
private JComboBox combo = new JComboBox();
private JLabel label = new JLabel("A list");
private JLabel label_2 = new JLabel ("Selection");
public Display(){
this.setTitle("Animation");
this.setSize(400, 350);
this.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
this.setLocationRelativeTo(null);
container.setLayout(new BorderLayout());
combo.setPreferredSize(new Dimension(190, 20));
//We create te list of elements for the top of the GUI
String[] tab = {"Option 1","Option 2","Option 3","Option 4","Option 5"};
combo = new JComboBox(tab);
//Listener for the selected option
combo.addActionListener(new ItemAction());
//We add elements from the top of the interface
JPanel top = new JPanel();
top.add(label);
top.add(combo);
container.add(top, BorderLayout.NORTH);
//We add elements from the center of the interface
URL url = getClass().getClassLoader().getResource("fire.gif");
Icon icon = new ImageIcon(url);
JLabel center = new JLabel(icon);
container.add(center, BorderLayout.CENTER);
//We add elements from the bottom of the interface
JPanel down = new JPanel();
down.add(label_2);
container.add(down,BorderLayout.SOUTH);
this.setContentPane(container);
this.setVisible(true);
this.setResizable(false);
}
class ItemAction implements ActionListener{
public void actionPerformed(ActionEvent e){
label_2.setText("Chosen option: "+combo.getSelectedItem().toString());
}
}
}
尝试这个:
// I suppose you have already set your JFrame
Icon imgIcon = new ImageIcon(this.getClass().getResource("ajax-loader.gif"));
JLabel label = new JLabel(imgIcon);
label.setBounds(668, 43, 46, 14); // for example, you can use your own values
frame.getContentPane().add(label);
