CustomTypefaceSpan fonte;
List<Fragment> fragments = new ArrayList<>(4);
private String[] icons = {"\ue001","\uE002","\uE003","\uE004"};

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

public List<Fragment> getFragments() {
    return fragments;
}

@Override
public Fragment getItem(int position) {
    return fragments.get(position);
}

@Override
public CharSequence getPageTitle(int position) {
    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 );
    return ss;
}



@Override
public int getCount() {
    return 4;
}
