Android下划线文本和保存到文本文件

Question

我想在Java中强调文本。 attendeeList项目来自我的数据库。这里是我的代码：

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++; 
      } 

我的文字的例子是：Attendee 1，Attendee 2等。但是，我收到如下错误消息：

Answer 1

setRenderingHint（）是AWT（桌面图形）API，它在Android上不存在。它也与文本下划线无关。只需删除此呼叫。

Answer 2

这不是在Android上强调文本的正确方法。你想这样的东西：

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);
