TextView as a button in quiz application not selected on clicking them

Question

I created a Quiz application in android and used TextView as buttons in Answers option but its not working and i don't know what I have done wrong in my code.

override fun onClick(v: View?) {
        when(v?.id) {
            R.id.tvOptionOne -> {
                selectedOptionView(binding.tvOptionOne,1)
            }
            R.id.tvOptionTwo -> {
                selectedOptionView(binding.tvOptionTwo,2)
            }
            R.id.tvOptionThree -> {
                selectedOptionView(binding.tvOptionThree,3)
            }
            R.id.tvOptionFour -> {
                selectedOptionView(binding.tvOptionFour, 4)
            }
            R.id.btnSubmit -> {
                if (mSelectedOptionPosition == 0){
                    mCurrentPossition++

                    when{
                        mCurrentPossition <= mQuestionList!!.size -> {
                            setQuestion()
                        }else ->{
                            Toast.makeText(this, "You have successfully compelted the quiz", Toast.LENGTH_SHORT).show()
                        }
                    }
                }else{
                    val question = mQuestionList?.get(mCurrentPossition -1)
                    if (question!!.correctAnswer != mSelectedOptionPosition){
                        answerView(mSelectedOptionPosition, R.drawable.wrong_option_border_bg)
                    }
                    answerView(question.correctAnswer, R.drawable.correct_option_border_bg)

                    if (mCurrentPossition == mQuestionList!!.size){
                        binding.btnSubmit.text = "FINISH"
                    }else{
                        binding.btnSubmit.text = "GO TO NEXT QUESTION"
                    }
                    mSelectedOptionPosition == 0
                }
            }
        }
    }

 private fun selectedOptionView(tv: TextView, seletedOptionNum:Int){

        defaultOptionsView()
        mSelectedOptionPosition = seletedOptionNum
        tv.setTextColor(Color.parseColor("#363A43"))
        tv.setTypeface(tv.typeface, Typeface.BOLD)
        tv.background = ContextCompat.getDrawable(this, R.drawable.selected_option_border_bg)

    }

This code should have resulted in highlight the clicked answer box but it shows nothing after clicking.enter image description here

Add this below code to your onCreate(for Activity), onViewCreated(for Fragment)

    tvOptionOne.setOnClickListener(this)
    tvOptionTwo.setOnClickListener(this)
    tvOptionThree.setOnClickListener(this)
    tvOptionFour.setOnClickListener(this)

we using this setOnClickListener(this) with id name for onClick operation for do a click event. – Sindhuja MK Jul 03 '23 at 06:01
Thanks! It worked. I was making the silly mistake of using curly braces instead of these braces. – Shakib Khatri Jul 04 '23 at 07:06
