Stuck on my first real project in Android Studio (Kotlin)

I'm new to coding in kotlin, and i'm kinda stuck. This is my first real project, and is an android app, where you can play "Never have i ever". I've just tried hopelessly, and i'm not sure how to get a random question from my .txt file where i've got my questions. I was thinking that it would be best to generate a random number, use the random number as a "line number", and then output it to my textview. But i really don't know how. This is just a silly attempt, but i would like it to work

import android.os.Bundle
import android.util.Log.d
import androidx.appcompat.app.AppCompatActivity
import kotlinx.android.synthetic.main.activity_gamingpage.*
import kotlin.random.Random
import java.io.File

class Gamingpage : AppCompatActivity() {
    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContentView(R.layout.activity_spilleside)

        //actionbar
        val actionbar = supportActionBar
        //set actionbar title
        actionbar!!.title = "New Activity"
        //set back button
        actionbar.setDisplayHomeAsUpEnabled(true)
        actionbar.setDisplayHomeAsUpEnabled(true)
        bigbutton.setOnClickListener {
            // Debug
            d("Console: ", "The next button was pressed")
            // A random value from 1 to 10, to make sure that every question is different. In the future 
            // it will become more than just 1-10
            val randomValues = List(1) { Random.nextInt(0, 10) }

            // More debug
            d("Console", " $randomValues")
            // Value of question, which is the random line number of my txt file with questions
            // It's also here where i'm stuck, and my app crashes
            val spm = File("app/src/main/spm_liste/question_list.txt").useLines(randomValues)
            // print used as debug
            println(spm)
            // My textview where the random question will be viewed
            question.text = listOf(spm).toString()

        }
    }


    override fun onSupportNavigateUp(): Boolean {
        onBackPressed()
        return true
    }
}

Thanks in advance!
