My 2p, Kotlin with reference checking, applicable everywhere as it will stop if something is wrong.

private fun setTabLayouFont(tabLayout: TabLayout) {
    val viewGroupTabLayout = tabLayout.getChildAt(0) as? ViewGroup?
    (0 until (viewGroupTabLayout?.childCount ?: return))
            .map { viewGroupTabLayout.getChildAt(it) as? ViewGroup? }
            .forEach { viewGroupTabItem ->
                (0 until (viewGroupTabItem?.childCount ?: return))
                        .mapNotNull { viewGroupTabItem.getChildAt(it) as? TextView }
                        .forEach { applyDefaultFontToTextView(it) }
            }
}
