Android Kotlin onItemSelectedListener for spinner not working

Question

I have a spinner with some items (strings). I want to add the selected items to a list. I read online that I should use the onItemSelectedListenerrather than the onItemClickListener.

I implemented this but I don't know how to complete the step of adding it to the list.

class NewKitListActivity : AppCompatActivity() {

var spinnerArray = arrayOf("Dumbell", "Punching Bag", "Yoga Ball", "Skipping Rope")
//var spinnerArray = arrayOf(DataService.kitList)



override fun onCreate(savedInstanceState: Bundle?) {
    super.onCreate(savedInstanceState)
    setContentView(R.layout.activity_new_kit_list)



    val spinner = newKitItemSpinner
    val spinnerArrayAdapter = ArrayAdapter<String>(this, android.R.layout.simple_spinner_dropdown_item, spinnerArray)
    //selected item will look like a spinner set from XML
    spinnerArrayAdapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item)
    spinner.adapter = spinnerArrayAdapter

    spinner.onItemSelectedListener = object : OnItemSelectedListener {
        override fun onItemSelected(parent: AdapterView<*>, view: View, position: Int, id: Long) {
            val selectedItem = parent.getItemAtPosition(position).toString()
            if (selectedItem == "Add new category") {
                // do your stuff
            }
        } // to close the onItemSelected

        override fun onNothingSelected(parent: AdapterView<*>) {

        }
    }}}

Thanks

(in Kotlin)Use this code:

yourSpinner?.onItemSelectedListener = object : AdapterView.OnItemSelectedListener{
        override fun onNothingSelected(parent: AdapterView<*>?) {

        }

        override fun onItemSelected(parent: AdapterView<*>?, view: View?, position: Int, id: Long) {

        }

    }
