title: Underline Textview
body: <p>Just a quick question:
  Do you know why i can do that:</p>
  
  <pre><code>pnrCode = (TextView)findViewById(R.id.pnr);
          SpannableString pnrContent = new SpannableString("PNR: ");
          pnrContent.setSpan(new UnderlineSpan(), 0, pnrContent.length(), 0);
          pnrCode.setText(pnrContent + BookingSettings.getBookingSegment().substring(0, 6));
  </code></pre>
  
  <p>The text is not underlined.</p>
  
  <p>Whereas, if i do only that:</p>
  
  <pre><code>  pnrCode = (TextView)findViewById(R.id.pnr);
              SpannableString pnrContent = new SpannableString("PNR: ");
              pnrContent.setSpan(new UnderlineSpan(), 0, pnrContent.length(), 0);
              pnrCode.setText(pnrContent);
  </code></pre>
  
  <p>The text is underlined.</p>
  
  <p>I have to create two textview ?
  Do you know another solution ?</p>
  
  <p>Any help is appreciated ;)</p>
