Question

When I create my activity, I setup a Spinner, assigning it a listener and an initial value. I know that the onItemSelected callback is called automatically during a

I am updating @Andres Q.'s answer in Kotlin.

Create an inner class in which you're using Spinner

inner class SpinnerInteractionListener : AdapterView.OnItemSelectedListener, View.OnTouchListener {
        override fun onNothingSelected(parent: AdapterView<*>?) {

        }

        override fun onItemSelected(parent: AdapterView<*>?, view: View?, position: Int, id: Long) {
            if (userSelect) {
                //Your selection handling code here
                userSelect = false
            }
        }

        @SuppressLint("ClickableViewAccessibility")
        override fun onTouch(v: View?, event: MotionEvent?): Boolean {
            userSelect = true
            return false
        }

        internal var userSelect = false
    }

Then declare instance variable outside onCreate() as globally like

lateinit var spinnerInteractionListener: SpinnerInteractionListener

then initialise it inside onCreate() by

spinnerInteractionListener = SpinnerInteractionListener()

and use it like

spinnerCategory.onItemSelectedListener = spinnerInteractionListener
spinnerCategory.setOnTouchListener(spinnerInteractionListener)

here spinnerCategory is Spinner
