Answer 2

Try following code

span.setSpan(new RelativeSizeSpan(0.8f), start, end,
            Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);

Here, you need to set start and end as per your requirement. 0.8f is size of text here. You need to pass float value here.

Code

textView = (TextView) findViewById(R.id.textView);
Spannable span = new SpannableString(textView.getText());
span.setSpan(new RelativeSizeSpan(0.8f), 0, 7,
            Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
span.setSpan(new RelativeSizeSpan(1.8f), 7,
            txt.getText().length(), Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
txt.setText(span);

Output
