你好，我试图创建一个简单的数字猜测应用程序，如果用户猜测的数字与随机数生成器匹配，textView应该输出“你已经正确地猜到了数字”或没有，但每当我按下按钮，程序崩溃。请帮助
每当我按下按钮时，程序就会崩溃。用户应在userAns变量中输入他们的数字，如果答案正确。应执行answerCorrect变量并显示文本，如果用户猜测的数字是错误的。应执行answerWrong变量。我是初学者，所以请帮助

class MainActivity : AppCompatActivity() {
     override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContentView(R.layout.activity_main)
        //Calling button method
        val button = findViewById<Button>(R.id.guessBtn)
        //Set on click listener for the button
        button.setOnClickListener {
            buttonPressed()
          }
         }
        //Creating button for button pressed
        private fun buttonPressed() {
            //Method to find view from activity_main
            val result = findViewById<TextView>(R.id.result)
            val userAns = findViewById<EditText>(R.id.answer).toString().toInt()
            //This variable will display the answer
            val answerCorrect = "Congrats, you have correctly guessed the number"
            val answerWrong = "Sorry,you have guessed the wrong number"
            //Making random numbers from 1 to 10
            var randomValues = Random.nextInt(1, 10)
            //Adding a condition to check if user answer matches the random answer
            if(userAns == randomValues){
                result.text = answerCorrect
            }
            else{
                result.text = answerWrong
            }

             }
             }
