SpannableString: Is it possible to apply two or more RelativeSizeSpans?

If you’re still looking for an answer, I might have a solution. I had similar problems. I used TextUtils to concat the 2 SpannableString.

Here is some example code:

SpannableString span1 = new SpannableString("32m");
SpannableString span2 = new SpannableString("50s");

span1.setSpan(new RelativeSizeSpan(0.75f),  2, 3, 0);
span2.setSpan(new RelativeSizeSpan(0.75f),  2, 3, 0);

mTextView.setText(TextUtils.concat(span1," " ,span2));
