Loading animated GIF in JLabel weirdness
提问by AlejandroVK
I'm trying to load an animated GIF in a JLabel.
我正在尝试在 JLabel 中加载动画 GIF。
While this works:
虽然这有效：
URL urlsd;
try {
urlsd = new URL("http://pscode.org/media/starzoom-thumb.gif");
ImageIcon imageIcon = new ImageIcon(urlsd);
JLabel progress = new JLabel(imageIcon);
progress.setBounds(5, 20, 66, 66);
contentPane.add(progress);
} catch (MalformedURLException e) {
e.printStackTrace();
}
This, on the other hand, does not, and I don't want to get the GIF from an URL, since I already have the GIF. Result of loading this shows only the first frame of the GIF:
另一方面，这不会，而且我不想从 URL 获取 GIF，因为我已经有了 GIF。加载结果仅显示 GIF 的第一帧：
try {
ImageIcon imageIcon = new ImageIcon(ImageIO.read(ClassLoader.getSystemResourceAsStream("res/images/progress_indicator.gif")));
JLabel progress = new JLabel(imageIcon);
imageIcon.setImageObserver(progress);
progress.setBounds(5, 20, 66, 66);
contentPane.add(progress);
} catch (MalformedURLException e) {
e.printStackTrace();
}
I guess there must be a reason for this, but I cannot find it.
我想这一定是有原因的，但我找不到。
Thanks! Alex

You can try loading your GIF file like that:
您可以尝试像这样加载您的 GIF 文件：
public class Test extends JPanel {
public Test() {
ImageIcon imageIcon =
new ImageIcon(Test.this.getClass().getResource("starzoom-thumb.gif"));
}
}
Or using Test.class.getResouce()if your context is static.
或者Test.class.getResouce()在您的上下文是静态的情况下使用。

Below code worked for me, it will show the animation instead of first frame of the image.
下面的代码对我有用，它将显示动画而不是图像的第一帧。
public class Test extends JPanel {
public Test() {
ImageIcon yyyyIcon = new ImageIcon(xxx.class.getClassLoader().getResource("yyyy.gif"));
connectionLabel.setIcon(yyyy);
}
}

So there is also a simpler way of doing it. The following line is how I did it.
所以还有一种更简单的方法。下面这行是我是怎么做的。
this.setContentPane(new JLabel(new ImageIcon("Path To Gif File")));
