• AFAIK, underline is not a supported style for native iPhone labels so I'd guess, that there's no way in Titanium. Don't know for Android, though.

• Worst case you can add a view with a height of 1 and the same width of the label placed directly under the label.

• Hi,
  you can easily wrap your label with a view which calculates the size of the label after a certain timeout and adds a line view.

  function decorateLabel(label) {
    var decoratedView = Titanium.UI.createView({
      width : Titanium.UI.SIZE, height : Titanium.UI.SIZE, layout : 'vertical', left : 0
    });
    decoratedView.add(label);
  
    setTimeout(function() {
      var lineView = Titanium.UI.createView({
        width : label.getSize().getWidth(), left : label.left, height : 1, backgroundColor : label.color ? label.color : 'white', top : -1, bottom : 0
      });
      decoratedView.add(lineView);
    }, 100);
  
    return decoratedView;
  }
  

• On iOS Titanium label does not support underline style (TiLabel is basically wrapped around the UILabel but doesnt utilise the attributedText). We've created a replacement for UILabel that supports underline along with other few goodies - you can try it here.
