Java - ImageIcon不会显示图像 [英] Java - ImageIcon won't show image

问题描述

searchIcon = new ImageIcon( "searchIcon.png" );

searchIconLabel = new JLabel();
searchIconLabel.setIcon(searchIcon);

....

searchHorizontalPanel.add( searchIconLabel );

我正在尝试加载图标，但它不会显示。 jpanel在boxlayout内。我不知道这是否会让事情变得混乱。这很奇怪，因为除了图标图像之外我还可以添加其他任何东西。我浏览了调试器，searchIcon显示宽度和高度为-1。这是否意味着图像未被加载？

I'm trying to load the icon but it won't show up. The jpanel is within a boxlayout. I don't know if that messes things up. It's strange because I can add pretty much anything else except icon images. I went through the debugger and searchIcon is showing the width and height to be -1. Does this mean the image is not being loaded?

推荐答案

您的图像文件需要与运行图像文件位于同一目录中来自。

Your image file needs to be in the same directory as you are running the application from.

如果它实际上与拨打电话的班级在同一目录中，那么你可以使用：

If its actually in the same directory as the class making the call then you can use:

searchIcon = new ImageIcon( getClass().getResource("searchIcon.png") );

如果它位于某个任意位置，那么您需要指定完整路径。

If it is in some arbitrary location then you will need to specify the full path.
