android - How to make a function when pressing a button in KOTLIN

Question

I created a function called "talk" so I want to press a button to execute "talk". I put this to do in the activity_main.xml and everything works fine. The problem comes when I don't want to do it by activity_main but by code in Mainactivity.kt. After the "talk" function is executed I want to make a condition. and I don't know how to do both when pressing the button.

imageButton.setOnClickListener{
talk()
if (textView3.text=="hello") {
textView.visibility = View.VISIBLE
} else {

}
}

this is the code of the function ""talk"" :

fun talk(v: View) {
        val intentActionRecognizeSpeech = Intent(
                RecognizerIntent.ACTION_RECOGNIZE_SPEECH)
        // Configura el Lenguaje (Espa?ol-México)
        intentActionRecognizeSpeech.putExtra(
                RecognizerIntent.EXTRA_LANGUAGE_MODEL, "es-MX")
        try {
            startActivityForResult(intentActionRecognizeSpeech,
                    RECOGNIZE_SPEECH_ACTIVITY)
        } catch (a: ActivityNotFoundException) {
            Toast.makeText(applicationContext,
                    "Tú dispositivo no soporta el reconocimiento por voz",
                    Toast.LENGTH_SHORT).show()
        }
    }
}
