android - 如何在android中为单个textview设置两种不同的大小

Question

In my android app i need to set two different sizes in single textview. i tried Spannable but not working correctly. what i tried was

String Amount = "Rs.109";                                     
Spannable Passspan = new SpannableString(Amount);
Passspan.setSpan(new RelativeSizeSpan(0.75f), 1, 3, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
txt.setTextSize(TypedValue.COMPLEX_UNIT_DIP, 12);   
txt.setText(Passspan);

I want "Rs." as text size of 10 and rest of them as text size of 15. The total count of amount may vary to different sizes such as "Rs.109" , "Rs.1000" like that . guide me...

Thank you very much for your support guys...This helps me to get two different font size in single textview.

String Amount="Rs.109";
txt.setTextSize(TypedValue.COMPLEX_UNIT_DIP, 15);
Spannable span = new SpannableString(Amount);
span.setSpan(new RelativeSizeSpan(0.75f), 0, 3,       
Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
txt.setText(span);
