How to format a text in JLabel
提问by user1533166
I need to display a JLabel text in this format.
我需要以这种格式显示 JLabel 文本。
Hoffenheim 1 : 0 Koeln
Bayern 2 : 1 HSV
I just can't get this done. I've tried String.format()without luck.
Any advice?
我就是做不到这件事。我试过String.format()没有运气。有什么建议吗？

You can use HTML. Read How to Use HTML in Swing Componentsfor details. For example you could build a table, similar to the following:
您可以使用 HTML。阅读如何在 Swing 组件中使用 HTML了解详细信息。例如，您可以构建一个表，类似于以下内容：
import javax.swing.JLabel;
import javax.swing.JOptionPane;
public class StringDemo {
public static void main(String arg[]){
StringBuilder buff = new StringBuilder();
buff.append("<html><table>");
buff.append(String.format("<tr><td align='right'>%s</td><td>:</td><td>%s</td></tr>", "Hoffenheim 1", "0 Koeln"));
buff.append(String.format("<tr><td align='right'>%s</td><td>:</td><td>%s</td></tr>", "Bayern 2", "1 HSV"));
buff.append("</table></html>");
JOptionPane.showMessageDialog(null, new JLabel(buff.toString()));
}
}

String.format()is used to insert content into a specially formatted string, not to display the string differently. JLabels and other Swing components do allow HTML however, which may get you what you need.
String.format()用于将内容插入到特殊格式的字符串中，而不是以不同的方式显示字符串。但是，JLabels 和其他 Swing 组件确实允许使用 HTML，这可能会满足您的需求。
new JLabel("<html><pre> Hoffenheim 1 : 0 Koeln</pre></html>");
new JLabel("<html><pre> Bayern 2 : 1 HSV</pre></html>");
That said, it looks like what you're asking for is to center your text around those colons, not just have them a given number of spaces away from the edge. That's going to be a little trickier, but still possible. To do this, you'll want to actually break everything up into several labels and arrange them in a grid (I find MigLayoutto be very good for things like this).
也就是说，看起来您要求的是将您的文本围绕这些冒号居中，而不仅仅是让它们远离边缘给定数量的空格。这会有点棘手，但仍然有可能。为此，您实际上需要将所有内容分解为多个标签并将它们排列在网格中（我发现MigLayout非常适合此类事情）。
Create six JLabels, left, right, or center aligningthem as appropriate, and drop then into a grid like so:
创建六个 JLabel，左、右或居中对齐，视情况而定，然后放入网格中，如下所示：
| Hoffenheim 1 | : | 0 Koeln |
| Bayern 2 | : | 1 HSV |
Obviously you can disable borders and so-on such that it doesn't appear to the user to be anything other than a nicely formatted bit of text.
很明显，您可以禁用边框等，这样它在用户看来就不会是格式良好的文本以外的任何东西。

Extending on from dimo414 answer you could actually use a HTML table
从 dimo414 答案扩展，您实际上可以使用 HTML 表格
StringBuilder sb = new StringBuilder(128);
sb.append("<html>");
sb.append("<table border='0'>");
sb.append("<tr>");
sb.append("<td align='right'>Hoffenheim</td>");
sb.append("<td align='center'>1</td>");
sb.append("<td align='center'>:</td>");
sb.append("<td align='center'>0</td>");
sb.append("<td align='left'>Koeln</td>");
sb.append("</tr>");
sb.append("<tr>");
sb.append("<td align='right'>Bayern</td>");
sb.append("<td align='center'>2</td>");
sb.append("<td align='center'>:</td>");
sb.append("<td align='center'>1</td>");
sb.append("<td align='left'>HSV</td>");
sb.append("</tr>");
sb.append("</table>");
sb.append("</html>");
label.setText(sb.toString());
While this is far more complicated, it gives you greater flexibility over the formatting.
虽然这要复杂得多，但它为您提供了更大的格式灵活性。
