Data Class Parameters to List - Kotlin android

I have a Kotlin data class with around 37 attributes/parameters. I'd like to get the values of all those parameters into a list. How can I do that in a clean, minimal and efficient way? I've tried searching, but haven't come across anything of the sort yet.

Any help would be appreciated. Thanks.

Edit

Each of the attributes/parameters is a string. I'm loading each of the strings in its own TextView in Android (Yes, 37 TextViews in a TableLayout each with their own labels. Kind of what a receipt would look like). But I don't want to do this (textView.text = myClass.parameter) 37 times.

Solution using reflection

Include kotlin-reflect

// Gradle Groovy DLS
implementation "org.jetbrains.kotlin:kotlin-reflect:${kotlin_version}"

// Gradle Kotlin DLS
implementation(kotlin("reflect"))

Suppose the following case

data class DataClass(val a: String, val b: String, val c: String, val d: String, val e: String)

val instance = DataClass("A", "B", "C", "D", "E")

DataClass::class.memberProperties.forEach { member ->
    val name = member.name
    val value = member.get(instance) as String

    findTextViewByName(name).text = value
}

It's up to you to implement findTextViewByName function
