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

I know this is an old question, but I came up with a nicer solution: I created this OnTabSelectedListener

class OnTabSelectedBoldListener : TabLayout.OnTabSelectedListener {
    override fun onTabReselected(tab: TabLayout.Tab) {}

    override fun onTabUnselected(tab: TabLayout.Tab) {
        val views = arrayListOf()
        tab.view.findViewsWithText(views, tab.text, View.FIND_VIEWS_WITH_TEXT)
        views.forEach { view ->
            if (view is TextView) {
                TextViewCompat.setTextAppearance(view, R.style.TabTextAppearance)
            }
        }
    }

    override fun onTabSelected(tab: TabLayout.Tab) {
        val views = arrayListOf()
        tab.view.findViewsWithText(views, tab.text, View.FIND_VIEWS_WITH_TEXT)
        views.forEach { view ->
            if (view is TextView) {
                TextViewCompat.setTextAppearance(view, R.style.TabTextAppearance_Selected)
            }
        }
    }
}
