就像这样：

override fun onReceive(context: Context, intent: Intent) {
        if (intent.action == Telephony.Sms.Intents.SMS_RECEIVED_ACTION) {
            val messages = Telephony.Sms.Intents.getMessagesFromIntent(intent)
            for (message in messages) {
               val sender = message.originatingAddress
               val body = message.messageBody
            }
        }
}
