How to change action bar title color in code

You can use a SpannableString and ForegroundColorSpan to set the colour of the title

    Spannable text = new SpannableString(actionBar.getTitle());
    text.setSpan(new ForegroundColorSpan(Color.BLUE), 0, text.length(), Spannable.SPAN_INCLUSIVE_INCLUSIVE);
    actionBar.setTitle(text);
