Значки FontAwesome 5+ не будут отображаться должным образом в программно созданном фрагменте

Question

Я пытаюсь использовать последнюю версию шрифта FontAwesome для TextView в LinearLayout, который я создал программным способом, но вместо этого отображается поле с крестиком.Я пробовал оба FontManager.getTypeface(activity!!.baseContext, FontManager.FONTAWESOME) и FontManager.getTypeface(activity!!.applicationContext, FontManager.FONTAWESOME), но ни один из них не работал.Я даже использую последний .otf файл, предоставленный FontAwesone.Я действительно не понимаю, что я сделал неправильно, потому что я следовал всем инструкциям на сайте FontAwesome.Проблема в том, что макет создается динамически или что-то еще?

Объект FontManager

object FontManager {
    private const val ROOT = "fonts/"
    internal const val FONTAWESOME = ROOT + "fontawesome5-free-regular.otf"

    internal fun getTypeface(context: Context, font: String): Typeface {
        return Typeface.createFromAsset(context.assets, font)
    }
}

Класс фрагмента

class MyFragment : androidx.fragment.app.Fragment() {
    override fun onCreateView(inflater: LayoutInflater, container: ViewGroup?, savedInstanceState: Bundle?): View? {
        val mainRelativeLayout = RelativeLayout(activity)

        // Layout Parameters for relative layout items
        val rlpCVPrimary = RelativeLayout.LayoutParams(RelativeLayout.LayoutParams.MATCH_PARENT,
                FrameLayout.LayoutParams.WRAP_CONTENT)
        val rlpTVPrimaryIcon = RelativeLayout.LayoutParams(LinearLayout.LayoutParams
                .WRAP_CONTENT,
                FrameLayout.LayoutParams.WRAP_CONTENT)
