For Kotlin Lover

Create an extension class for custom asset font

    /**
      * Method for Bottom Navigation Font Family
      *@param view
      *
      * */
private fun navigationTextFont(view: View) {
    if (view is ViewGroup) {
        for (i in 0 until view.childCount) {
            val child = view.getChildAt(i)
            navigationTextFont(child)
        }
    } else if (view is TextView) {
        view.typeface = Typeface.createFromAsset(this.assets, "fonts/roboto_bold.ttf")
    }
}

Now call this extension

   navigationTextFont(yourNavigationViewId)

Good Luck
