public class RelativeSizeSpan extends MetricAffectingSpan implements icyllis.modernui.text.ParcelableSpan
Uniformly scales the size of the text to which it's attached by a certain proportion.

For example, a RelativeSizeSpan that increases the text size by 50% can be constructed like this: 


 SpannableString string = new SpannableString("Text with relative size span");
 string.setSpan(new RelativeSizeSpan(1.5f), 10, 24, Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);
