大家好，我在点击按钮时遇到问题

    fun mainPage(view: View) {
            val intent = Intent(applicationContext, MainActivity::class.java)
            intent.putExtra("input", userText.text.toString())
            startActivity(intent)
        }

       //second button started in here
         singupButton.setOnClickListener {
            fun crtUser (view: View) {
                val intent = Intent(applicationContext,createUser::class.java)
                startActivity(intent)
            }
        }

但我的按钮不起作用。我的问题在哪里？
