Question

我试图在Java中强调文本。 attendeeList项目来自我的数据库。这是我的代码：

for (int i = 0; i < attendeeList.size(); i++) {
                attendeeCounterStr = "\nAttendee " + counter;
                attendeeStrBuilder.append(attendeeCounterStr);
                g.setRenderingHint(RenderingHints.KEY_ANTIALIASING,
                        RenderingHints.VALUE_ANTIALIAS_ON);
                Font plainFont = new Font("Times New Roman", Font.PLAIN, 24);

                AttributedString as = new AttributedString(
                        attendeeCounterStr);
                as.addAttribute(TextAttribute.FONT, plainFont);
                as.addAttribute(TextAttribute.UNDERLINE,
                        TextAttribute.UNDERLINE_ON, 0, 10);
                g.drawString(as.getIterator(), 24, 70);

                counter++;
            }

我的文字示例包括：Attendee 1，Attendee 2等。但是，我收到错误消息：

Answer 1

这是在Android上为文字加下划线的正确方法。你想要这样的东西：

TextView textView = (TextView) view.findViewById(R.id.viewid);
SpannableString content = new SpannableString("Something to be underlined");
content.setSpan(new UnderlineSpan(), 0, content.length(), 0);
textView.setText(content);

Answer 2

setRenderingHint（）是一个AWT（桌面图形）API，它并不存在于Android上。它也与文本下划线无关。只需删除此电话即可。

Android下划线文字＆amp;保存到文本文件
