title: Html formatted text in NumberPicker
body: <p>I'm using a <code>NumberPicker</code> and I want to add a suffix for each number.</p>
  
  <p>I know that I can do this:</p>
  
  <pre><code>picker.setFormatter(new NumberPicker.Formatter() {
      @Override
      public String format(int value) {
          return value + " suffix");
      }
  });
  </code></pre>
  
  <p>But I want the suffix to be a subscript. So I tried this:</p>
  
  <pre><code>picker.setFormatter(new NumberPicker.Formatter() {
      @Override
      public String format(int value) {
          return value + " " + Html.fromHtml("&lt;sub&gt;suffix&lt;/sub&gt;")
      }
  });
  </code></pre>
  
  <p>But it's not working - the format is not applied; the suffix is not a subscript. That's obviously because <code>fromHtml</code> returns <code>Spanned</code> and then I'm converting it to <code>String</code>.</p>
  
  <p>So can I apply an Html formatted string on the picker?</p>
