Customized adapter

[iqbbal]

As per the documentation On customized adapters, you must call the spinnerView.notifyItemSelected method when your item is clicked or the spinner item needs to be changed. how to get the value for NO_SELECTED_INDEX? Thanks

override fun onBindViewHolder(holder: MySpinnerViewHolder, position: Int) {
holder.itemView.setOnClickListener {
notifyItemSelected(position)
}
}

// we must call the spinnerView.notifyItemSelected method to let PowerSpinnerView know about changed information.
override fun notifyItemSelected(index: Int) {
if (index == NO_SELECTED_INDEX) return
val oldIndex = this.index
this.index = index
this.spinnerView.notifyItemSelected(index, this.spinnerItems[index].text)
this.onSpinnerItemSelectedListener?.onItemSelected(
oldIndex = oldIndex,
oldItem = oldIndex.takeIf { it != NO_SELECTED_INDEX }?.let { spinnerItems[oldIndex] },
newIndex = index,
newItem = item
)
}
