public TabAdapter(FragmentManager fm, CustomTypefaceSpan fonte) {
    super(fm);
    this.fonte = fonte
    for (int i = 0; i < 4; i++){

    SpannableStringBuilder ss = new SpannableStringBuilder(icons[position]);
    ss.setSpan(fonte,0,ss.length(), Spanned.SPAN_INCLUSIVE_INCLUSIVE);
    ss.setSpan(new RelativeSizeSpan(1.5f),0,ss.length(), Spanned.SPAN_INCLUSIVE_INCLUSIVE );
