This class is deprecated.
along with ActionPage

ActionLabel is a specialized text display widget. An upper and lower bound for text size and a maximum number of lines are provided and the layout is adjusted automatically to find the largest possible text size satisfying those constraints.

In order to provide a fixed bound, an ActionLabel should always be used with a width and height of "match_parent" or a specific size. When created programmatically, you must supply a LayoutParams to do this: 

 LayoutParams lp = new ViewGroup.LayoutParams(200, 50);
 parent.addView(label, lp);

Supported attributes are:

  • text
  • textColor
  • maxLines
  • minTextSize
  • maxTextSize
  • lineSpacingExtra
  • lineSpacingMultiplier
  • fontFamily
  • typeface
  • textStyle
  • gravity
