推荐答案

您可以从 LocalContext 获取当前活动.这个使用活动你可以得到意图:

You can get current activity from the LocalContext. And this using activity you can get intent:

val context = LocalContext.current
val activity = context.findActivity()
val intent = activity?.intent

findActivity:

fun Context.findActivity(): Activity? = when (this) {
    is Activity -> this
    is ContextWrapper -> baseContext.findActivity()
    else -> null
}
