为什么 JTextPane 中的超链接（一个标签）保持在中心（中心对齐）

Question

我已经实现了两种方法，以便在JTextPane 中添加文本和超链接。问题是超链接显示为居中对齐，而不是文本（我希望两者都左对齐）。

方法是：

public void addText (String log, Color c, boolean bold) {

    StyledDocument doc = jTextPane.getStyledDocument();

    SimpleAttributeSet attrs = new SimpleAttributeSet();

    StyleConstants.setFontFamily(attrs, "Calibri");

    StyleConstants.setFontSize(attrs, 13);

    StyleConstants.setForeground(attrs, c);

    StyleConstants.setBold(attrs, bold);

    try {

        doc.insertString(doc.getLength(), log, attrs);

    } catch (BadLocationException ex) {

        Logger.getLogger(FrameLog.class.getName()).log(Level.SEVERE, null, ex);

    }

}

public void addHyperlink (URL url, String text) {

    StyledDocument doc = jTextPane.getStyledDocument();

    SimpleAttributeSet hrefAttr = new SimpleAttributeSet();

    hrefAttr.addAttribute(HTML.Attribute.HREF, url.toString());

    SimpleAttributeSet attrs = new SimpleAttributeSet();

    attrs.addAttribute(HTML.Tag.A, hrefAttr);

    StyleConstants.setFontFamily(attrs, "Calibri");

    StyleConstants.setFontSize(attrs, 13);

    StyleConstants.setForeground(attrs, Color.blue);

    try {

        doc.insertString(doc.getLength(), text, attrs);

    } catch (BadLocationException e) {

        e.printStackTrace(System.err);

    }

}

结果是这样的：

有谁知道我该如何解决这个问题？

我用一个泛型替换了我以前的方法，它将一些 html 代码附加到 JTextPane 中。新方法是：&nbsp; &nbsp; public void appendTextPane (String html) {&nbsp; &nbsp; &nbsp; &nbsp; HTMLEditorKit editor = (HTMLEditorKit) jTextPane.getEditorKit();&nbsp; &nbsp; &nbsp; &nbsp; HTMLDocument doc = (HTMLDocument) jTextPane.getDocument();&nbsp; &nbsp; &nbsp; &nbsp; String TAG;&nbsp; &nbsp; &nbsp; &nbsp; if (html.charAt(0) != '<') {&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; TAG = "";&nbsp; &nbsp; &nbsp; &nbsp; } else {&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; int nextSpaceIdx = html.indexOf(" ");&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; int nextBrcktIdx = html.indexOf(">");&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; TAG = html.substring(1, nextBrcktIdx < nextSpaceIdx ? nextBrcktIdx : nextSpaceIdx);&nbsp; &nbsp; &nbsp; &nbsp; }//&nbsp; &nbsp; &nbsp; &nbsp; System.out.println(jTextPane.getText());&nbsp; &nbsp; &nbsp; &nbsp; try {&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; editor.insertHTML(doc, doc.getLength(), html.replaceAll(" ", "&#160;"), 0, 0, HTML.getTag(TAG));&nbsp; &nbsp; &nbsp; &nbsp; } catch (IOException | BadLocationException ex) {&nbsp;

值得一提的是，当我尝试操作文档中的 HTML 文本时，我有一些旧的（丑陋的）代码。我使用了除insertString(...). 也许这会给你一些想法？import java.awt.*;import java.io.*;import java.awt.event.*;import javax.swing.*;import javax.swing.text.*;import javax.swing.text.html.*;public class TextPaneHTML extends JFrame implements ActionListener{&nbsp;
