How do I change the text style of a selected tab when using tabLayout?

Question

I want to make the text of a selected tab bold. How can I do this either through xml or java code, whatever is easier.

Answer 1

In addition to previous answers, bear in mind that when modifying the style of the text in the onTabUnselected you may have to recalculate the width of the view if it was set on WRAP_CONTENT

    @Override
    public void onTabSelected(TabLayout.Tab tab) {
            TextView text = (TextView) tab.getCustomView();
            text.setTypeface(null, Typeface.BOLD); 
            text.getCustomView().measure(WRAP_CONTENT, WRAP_CONTENT)
            text.getCustomView().layoutParams.height = measuredHeight
            text.getCustomView().layoutParams.width = measuredWidth
    }
