java - Android 为文本添加下划线并保存到文本文件

Question

我正在尝试在 Java 中为文本添加下划线。 attendeeList 项目来 self 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++;
            }

我的文本示例是:Attendee 1、Attendee 2 等。但是，我收到这样的错误消息:

这不是在 Android 上为文本添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);
