Android Custom font Spannable Typeface Span

Question

I am using Helvetica fonts throughout my application. Currently I am creating the fonts separately from assets. So I have say these three

HelveticaNeue = Typeface.createFromAsset(application.getAssets(), "fonts/HelveticaNeue.ttf"); HelveticaNeueBold = Typeface.createFromAsset(application.getAssets(), "fonts/HelveticaNeueBold.ttf"); HelveticaNeueBoldItalic = Typeface.createFromAsset(application.getAssets(), "fonts/HelveticaNeueBoldItalic.ttf"); 

Everything works great when I use one typeface for one TextView. However, I need to use a spannable

Spannable WordtoSpan = new SpannableString("This text should be normal, but this needs to be bold, and normal");     WordtoSpan.setSpan(new TypefaceSpan("bold"), 5, 7, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE); 

And I want to have part of the string be HeleveticaNeueBold and some be just HelveticaNeue. I think what is needed is to indicate to Android that the 3 fonts above are actually related so that it can switch them nicely. Looking for any other way of doing this as well.

You are going to want to write a custom TypefaceSpan. The good news is that they aren't difficult. See here for an example.
