把下面的代码转成kotlin private String notificationId = "serviceid"; private String notificationName = "servicename"; private void showNotification(){ notificationManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE); //创建NotificationChannel if(Build.VERSION.SDK_INT >= Build.VERSION_CODES.O){ NotificationChannel channel = new NotificationChannel(notificationId, notificationName, NotificationManager.IMPORTAN CE_HIGH); notificationManager.createNotificationChannel(channel); } startForeground(1,getNotification()); } private Notification getNotification() { Notification.Builder builder = new Notification.Builder(this) .setSmallIcon(R.mipmap.ic_launcher) .setContentTitle("title") .setContentText("text"); if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) { builder.setChannelId(notificationId); } Notification notification = builder.build(); return notification; }

以下是将Java代码转换为Kotlin代码的结果：

private var notificationId = "serviceid"
private var notificationName = "servicename"

private fun showNotification() {
    val notificationManager = getSystemService(Context.NOTIFICATION_SERVICE) as NotificationManager
    // 创建NotificationChannel
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
        val channel = NotificationChannel(notificationId, notificationName, NotificationManager.IMPORTANCE_HIGH)
        notificationManager.createNotificationChannel(channel)
    }
    startForeground(1, getNotification())
}

private fun getNotification(): Notification {
    val builder = Notification.Builder(this)
        .setSmallIcon(R.mipmap.ic_launcher)
        .setContentTitle("title")
        .setContentText("text")
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
        builder.setChannelId(notificationId)
    }
    return builder.build()
}

请注意，Kotlin中不需要使用分号来结束语句。此外，在Kotlin中，我们使用var和val关键字来声明变量和常量。在转换过程中，我还将notificationManager变量声明为局部变量，因为它只在showNotification()函数中使用。
