可以使用LocalFontFamilyResolver从androidx.compose.ui.text.TextStyle对象解析android.graphics.Typeface对象。

val style: TextStyle = MaterialTheme.typography.body1
val resolver: FontFamily.Resolver = LocalFontFamilyResolver.current

val typeface: Typeface = remember(resolver, style) {
    resolver.resolve(
        fontFamily = style.fontFamily,
        fontWeight = style.fontWeight ?: FontWeight.Normal,
        fontStyle = style.fontStyle ?: FontStyle.Normal,
        fontSynthesis = style.fontSynthesis ?: FontSynthesis.All,
    )
}.value as Typeface

我不认为有一种方法可以将排版字体转换为本机字体。目前，我找到的唯一解决方法是提供资源：

val textTypeface: android.graphics.Typeface? =
        if (Build.VERSION.SDK_INT > Build.VERSION_CODES.O) LocalContext.current.resources.getFont(R.font.quicksand_light) else null

然而，如果Android版本〈Android oreo，idk如何提供字体，所以我回退到默认字体。
