TextView title = (TextView)(((LinearLayout ((LinearLayout) mTabLayout.getChildAt(0)).getChildAt(tabPosition)).getChildAt(1));
title.setTextSize(...);

Answer 3

显示粗体文本

tabLayout.addOnTabSelectedListener(tabSelectedListener)

private val tabSelectedListener = object : TabLayout.OnTabSelectedListener {
  override fun onTabSelected(tab: TabLayout.Tab?) {
    tab?.view?.children?.forEach {
      if (it is TextView) {
        it.post {
          it.setTypeface(ResourcesCompat.getFont(context, R.font.bold_font_name), Typeface.NORMAL)
        }
      }
    }
  }

  override fun onTabUnselected(tab: TabLayout.Tab?) {
    tab?.view?.children?.forEach {
      if (it is TextView) {
        it.post {
          it.setTypeface(ResourcesCompat.getFont(context, R.font.font_name), Typeface.NORMAL)
        }
      }
    }
  }

  override fun onTabReselected(tab: TabLayout.Tab?) {}
}
