// Setup single span

CharSequence formattedText1 = Trestle.getFormattedText(
        new Span.Builder("ForegroundSpan, BackgroundSpan, and CustomTypefaceSpan")
                .foregroundColor(getContext(), R.color.purple_100)
                .backgroundColor(getContext(), R.color.green_500)
                .typeface(italicFont)
                .build());

tv1.setText(formattedText1);

// Setup multiple spans
TextView tv2 = (TextView) view.findViewById(R.id.tv2);

List<Span> spans1 = new ArrayList<>();
spans1.add(new Span.Builder("ForegroundSpan")
        .foregroundColor(getContext(), R.color.red_500)
        .build());
spans1.add(new Span.Builder("BackgroundSpan")
        .backgroundColor(getContext(), R.color.yellow_500) 
        .build());
spans1.add(new Span.Builder("ForegroundSpan and BackgroundSpan")
        .foregroundColor(getContext(), R.color.blue_500)
        .backgroundColor(getContext(), R.color.blue_300)
        .build());
spans1.add(new Span.Builder("ForegroundSpan, BackgroundSpan, and CustomTypefaceSpan")
        .foregroundColor(getContext(), R.color.yellow_500)
        .backgroundColor(getContext(), R.color.indigo_200) 
        .typeface(regularFont)
        .build());

CharSequence formattedText2 = Trestle.getFormattedText(spans1);
