Change your 3rd parameter name of onItemSelected
position
to pos
. Because position
is already used in your onBindViewHolder
and when you use items[position]
it use position
of onItemSelected
but you have to use the position
parameter of onBindViewHolder
.
override fun onItemSelected(parent: AdapterView<*>?, view: View?, pos: Int, id: Long){
selectedQty = values[pos] // here you should use pos
if (pos == 0) { // need to chnage also here and below conditions
holder.product_price.text = "Rs. " + (items[position].price.toDouble() * 0.25)
} else if (pos == 1) {
holder.product_price.text = "Rs. " + (items[position].price.toDouble() * 0.50)
} else if (pos == 2) {
holder.product_price.text = "Rs. " + (items[position].price.toDouble() * 1.00)
} else if (pos == 3) {
holder.product_price.text = "Rs. " + (items[position].price.toDouble() * 2.00)
} else if (pos == 4) {
holder.product_price.text = "Rs. " + (items[position].price.toDouble() * 3.00)
}
