Remarks
Span that updates the typeface of the text it's attached to. The TypefaceSpan can be constructed either based on a font family or based on a Typeface. When #TypefaceSpan(String) is used, the previous style of the TextView is kept. When #TypefaceSpan(Typeface) is used, the Typeface style replaces the TextView's style.
For example, let's consider a TextView with android:textStyle="italic" and a typeface created based on a font from resources, with a bold style. When applying a TypefaceSpan based the typeface, the text will only keep the bold style, overriding the TextView's textStyle. When applying a TypefaceSpan based on a font family: "monospace", the resulted text will keep the italic style.
Typeface myTypeface = Typeface.create(ResourcesCompat.getFont(context, R.font.acme),
Typeface.BOLD);
SpannableString string = new SpannableString("Text with typeface span.");
string.setSpan(new TypefaceSpan(myTypeface), 10, 18, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
string.setSpan(new TypefaceSpan("monospace"), 19, 22, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
