Answer 1

You can use RelativeSizeSpan

numSpan.setSpan(new SuperscriptSpan(), 0, numSpan.length(), Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
numSpan.setSpan(new RelativeSizeSpan(0.5f), 0, numSpan.length(), Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);

or AbsoluteSizeSpan

numSpan.setSpan(new SuperscriptSpan(), 0, numSpan.length(), Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
numSpan.setSpan(new AbsoluteSizeSpan(28), 0, numSpan.length(), Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
