title: Change the color of the underline in android
body: <p>I am developing the android application. I need to underline some of the Textview.</p>
  
  <pre><code>SpannableString content = new SpannableString("Ack:");
  content.setSpan(new UnderlineSpan(), 0, content.length(), 0);
  tvAck.setText(content);` 
  </code></pre>
  
  <p>I have used the above code for that. But now i want to change the color of the underline. Can any one tell me how to do so. Any help or suggestion is accepted.</p>
