我想在使用Typeface设置样式后将示例文本的样式形式复制到剪贴板，但复制时它被复制为未设置样式。如何复制样式文本？

binding.buttonStyle.setOnClickListener {
            val textStyleSample = TextStyle(
                0,
                "Sample Text",
                CustomFontStyle.rubik_pixels_regular
            )

            val spannable = SpannableString(textStyleSample.text)
            spannable.setSpan(
                makeStyleForText(textStyleSample),
                0,
                textStyleSample.text.length,
                Spannable.SPAN_EXCLUSIVE_EXCLUSIVE
            )

            val clipboardManager = requireContext().getSystemService(Context.CLIPBOARD_SERVICE) as ClipboardManager
            val clipData = ClipData.newPlainText(
                "styledText",
                spannable.toString()
            )
            clipboardManager.setPrimaryClip(clipData)
        }

data class TextStyle(
    val id: Int, var text: String, var customFontStyle: CustomFontStyle
)

enum class CustomFontStyle {
    rubik_pixels_regular,
    inspiration_regular,
}

private fun makeStyleForText(textStyle: TextStyle): Typeface {
        return Typeface.createFromAsset(
            requireContext().assets,
            "${textStyle.customFontStyle}.ttf"
        )
    }
