        String detail = "ABC";
        String caption = String.format("2 %s", detail);

        int detailIndex = caption.indexOf(detail);

        span.setSpan(new StyleSpan(Typeface.BOLD), 0, detailIndex, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
        span.setSpan(new RelativeSizeSpan(0.5f), detailIndex, detailIndex+detail.length(), Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);

        button.setText(span);

        return rootView; …
