How do I define a textview outside of the activity class?

I have a location listener object, and I wanted to know how to define a TextView outside of the activity class. In LayoutInflater.from(context).inflate(R.layout.main, null) I get an unresolved reference for 'context' and 'main'. For val locTextView = MainActivity.findViewById(R.id.locTextView) as TextView1 I get an unresolved reference for findViewById.

private val locationListener: LocationListener = object : LocationListener {
    override fun onLocationChanged(location: Location) {
        val v = LayoutInflater.from(context).inflate(R.layout.main, null)
        val locTextView = MainActivity.findViewById(R.id.locTextView) as TextView
        locTextView.setText("" + location.longitude + ":" + location.latitude);
    }
    override fun onStatusChanged(provider: String, status: Int, extras: Bundle) {}
    override fun onProviderEnabled(provider: String) {}
    override fun onProviderDisabled(provider: String) {}
}

change your this line 

val v = LayoutInflater.from(context).inflate(R.layout.main, null)

with

val v = LayoutInflater.from(applicationContext).inflate(R.layout.main, null)

and again change your 

MainActivity.findViewById(R.id.locTextView) as TextView

with 

 val locTextView =  findViewById< TextView>(R.id.locTextView)

UPDATE

If you would like to use Kotlin Android Extention , then say goodbye to findViewById()
