Android : Android SpannableString EditText disable interaction

i have a situation where I build a string of "Happy Friday - with friendA, friendB"

I'm using SpannableString:

SpannableString content = new SpannableString(original);
content.setSpan(new StyleSpan(Typeface.ITALIC), original.lastIndexOf(" - with "), content.length(), 0);
editText.setText(content);

I can achieve a italic style of " - with friendA, friendB".

What I'd like to achieve is to disable editing or touch on the SpannableString (" - with friendA, friendB"), but I can still edit the editText...is there any workarounds? Thanks.
