当我按下按钮时，Kotlin 会改变 2 个分数

Question

我有两个乐谱和一个按钮。我想增加第一个分数，5 秒后增加第二个分数相同的按钮。有代码倒计时器

tt = object : CountDownTimer(5000,1000){
           override fun onTick(p0: Long) {
               binding.time.text = (p0/1000).toString()
           }
           override fun onFinish() {
               val dialogView = LayoutInflater.from(context).inflate(R.layout.dialogcard,null)
               val alert = AlertDialog.Builder(context)
               alert.setView(dialogView)
               alert.setCancelable(false)
               alert.setPositiveButton("Go") { dialogInterface: DialogInterface, i: Int ->
                   if (!textChanged){
                       binding.teamName.text = arguments?.getString("teamName2")
                 //      binding.scoreText.text = secondTeamScore.toString()
                       textChanged = true
                   } else {
                       binding.teamName.text = arguments?.getString("teamName1")
                   //    binding.scoreText.text = secondTeamScore.toString()
                       textChanged = false
                   }
                   tt.start()
               }.show()
           }
       }
       tt.start()
   }

这里的按钮代码：

binding.trueButton.setOnClickListener {
                                    firstTeamScore++
                                    binding.scoreText.text = firstTeamScore.toString()
                                    secondTeamScore++
                                    binding.scoreText.text = secondTeamScore.toString()
}

我该怎么办

可能的解决方案之一是使用 kotlin 协程。示例代码：

CoroutineScope(Dispatchers.Main).async {
        delay(5000)
        secondTeamScore++
}
