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);

Answer 2

Try Html.fromHtml instead. Simple and precise:

outputText.setText(Html.fromHtml("<sup>" + num + "</sup>/<sub>" + den + "</sub>"));

Note: You may need to give some height to the textview else the output will be clipped.

Alternatively, you could try this, where the number size is smaller:

outputText.setText(Html.fromHtml("<sup><small>" + num + "</small></sup>/<sub><small>" + den + "</small></sub>"));
