Change font on TabLayout using Calligraphy

private void initTabs() {
        TabPagerAdapter adapter = new TabPagerAdapter(getSupportFragmentManager());
        pager.setAdapter(adapter);
        tabLayout.setupWithViewPager(pager);
        //tabLayout it doesn't respond to style attribute 'tabTextAppearance' so we have to use customview
        for (int i = 0; i < adapter.getCount(); i++) {
            TabLayout.Tab tab = tabLayout.getTabAt(i);
            if (tab != null) {
                tab.setCustomView(R.layout.tab_text);
                tab.setText(adapter.getPageTitle(i));
            }
        }
    }
