Second Challenge: Tracking cheat status by question

In this one I created a list in MainActivity

//questions they cheated on
var cheatedList = mutableListOf<Int>()

and added the index of the cheated questions to it from the clicklistener of the CheatActivity

 showAnswerButton.setOnClickListener {
        val answerText = when{
            answerIsTrue -> R.string.true_button
            else -> R.string.false_button
        }
        answerTextView.setText(answerText)
        //create a function to return the result to MainActivity
        setAnswerShownResult(true)
        cheaterStatus = true

        cheatedList.add(currentIndex)

    }

then in the checkAnswer function, i checked if the list contains the current index, if so display the judgment message

private fun checkAnswer(userAnswer : Boolean) {
        val correctAnswer = quizViewModel.questionBank[quizViewModel.currentIndex].answer
        val messageResId = if (cheatedList.contains(quizViewModel.currentIndex)) {
            R.string.judgment_toast
        } else if (userAnswer == correctAnswer) {

                if (::answersMap.isInitialized) {
                    answersMap.put(quizViewModel.currentIndex, true)
                } else {
                    answersMap = mutableMapOf(quizViewModel.currentIndex to true)
                }
                R.string.correct_toast

            } else {
                if (::answersMap.isInitialized) {
                    answersMap.put(quizViewModel.currentIndex, false)
                } else {
                    answersMap = mutableMapOf(quizViewModel.currentIndex to false)
                }
                R.string.false_toast
            }

            Toast.makeText(this, messageResId, Toast.LENGTH_SHORT).show()

        }

there you go…
