Here's the code I use to make an arbitrary CharSequence "smaller"
private static final float SMALL_TEXT_RELATIVE_SIZE = 0.8f;
public static CharSequence makeSmaller(CharSequence text)
{
SpannableStringBuilder smaller = new SpannableStringBuilder(text);
smaller.setSpan(new RelativeSizeSpan(SMALL_TEXT_RELATIVE_SIZE), 0,
text.length(), Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);
return smaller;
}
Once you have the "smaller" text, you can use TextUtils.concat() to build
up you final text. Just make sure you nowhere cast/toString() the
CharSequence to a String because you will lose the formatting info.
