Custom onItemClickListener for AutocompleteTextView

I would like to programmatically select item from ArrayAdapter<String> based on String value given if it exists. How can I do it?

I have this solution:

onAddressPickListener = AdapterView.OnItemClickListener { parent, _, position, _ ->
      pickedAddress = parent.getItemAtPosition(position).toString()
      //do something later
}

addressEt?.onItemClickListener = onAddressPickListener
addressList.addAll(newList)
addressAdapter = AddressPickerAdapter(a, R.layout.address_list_item, addressList)
addressEt?.setAdapter(addressAdapter)
addressEt?.threshold = 0

Somewhere else in code:

address?.let { currAddress ->
       val addressIndex = addressList.indexOf(currAddress)
       if (addressIndex != -1){
          addressAdapter?.let { adapter->
             val addressId = adapter.getItemId(addressIndex)
             val addressView = adapter.getView(addressIndex, **NONE(convertView)**, **NONE(parent)**)
             addressEt?.let { onAddressPickListener?.onItemClick(**NONE(AdapterView)**, **NONE(View)**, addressIndex, addressId) }
          }
       }
    }

Values marked as NONE(something) are unknown parameters. I don't know how or where to get their values from. addressEt is AutocompleteTextView.
