展示动画gif

Question

您如何在Java应用程序中显示动画GIF？

Answer 1

swing

您可以简单地使用一个：：

JLabel

检查它：

Answer 2

http：//java.sun.com/docs/books/tutorial/uiswing/components/icon.html#getresource

对于加载存储在源软件包（源代码）中的动画gifs，这对我有用：

Answer 3

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);
}

这为我工作！

Answer 4

URL url = MyClass.class.getResource("/res/images/animated.gif");
ImageIcon imageIcon = new ImageIcon(url);
JLabel label = new JLabel(imageIcon);

我来这里寻找相同的答案，但是根据最高答案，我提出了一个更容易的代码。希望这将有助于将来的搜索。

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);
    }

Answer 5

快速而简单的代码：

Icon icon = new ImageIcon("src/path.gif");
            try {
                mainframe.setContentPane(new JLabel(icon));
            } catch (Exception e) {
            }

Answer 6

不要忘记让Jframe可见和尺寸。

Icon icon = new ImageIcon("src/image.gif");
JLabel label = new JLabel();

label.setIcon(icon);

我想将.gif文件放入GUI中，但与其他元素一起显示。 .gif文件将来自Java项目，而不是从URL中获取。

Answer 7

2-中心将是动画的gif3-底部将显示从列表选择的元素

Answer 8

1 -Interf.java

//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);
   }
}

2-display.java

Infos：要在您的Java项目中创建一个新的源文件夹（新>源文件夹），然后将.GIF放入其中以将其视为文件。

我将GIF文件带有下面的代码，因此我可以将其导出到JAR项目中（然后是动画）。

urlurl = getClass（）。getClassLoader（）。getResource（“ fire.gif”）;

public class Interface_for {

    public static void main(String[] args) {

        Display Fr = new Display();

    }
}

  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());
      }
  }
}

使用“ file：” forurl

trone this：

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);
}

Answer 9

中显示动画gif

// 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);
