Como substituir o performClick no Kotlin para evitar aviso.

next.setOnTouchListener(View.OnTouchListener { view, motionEvent ->
        when (motionEvent.action){
            MotionEvent.ACTION_DOWN -> {
                val icon: Drawable = ContextCompat.getDrawable(activity.applicationContext, R.drawable.layer_bt_next)
                icon.setColorFilter(Color.GRAY, PorterDuff.Mode.MULTIPLY)
                next.setImageDrawable(icon)
            }
            MotionEvent.ACTION_UP -> {
                //view.performClick()
                next.setImageResource(R.drawable.layer_bt_next)
            }
        }
        return@OnTouchListener true
    })

view.performClick não funciona.
