Spinner in RecyclerView to update item values - android-recyclerview

Question

How can I update the values in my Dataset from a Spinner selection in a RecyclerView? Should I be using LiveData and Room with notifyItemChange(), data binding, or something simpler? I have a Horseclass and a HorseData class. The number of items is static and the options for the variables are static. I do not need to add values or items, I just need to be able to select the variable WinPercentHorse for each item and have that value saved back to the dataset.
public class HorseAdapter extends RecyclerView.Adapter<HorseViewHolder> {
private AdapterView.OnItemSelectedListener onItemSelectedListener;
//we are storing all the horses in a list
private List<Horse> horseList;
//this context we will use to inflate the layout
private Context mCtx;
//getting the context and product list with constructor
public HorseAdapter(Context mCtx, List<Horse> horseList) {
this.mCtx = mCtx;
this.horseList = horseList;
}
#Override
public HorseViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
//inflating and returning our view holder
LayoutInflater inflater = LayoutInflater.from(mCtx);
View view = inflater.inflate(R.layout.item_layout, null);
return new HorseViewHolder(view);
}
#Override
public void onBindViewHolder(final HorseViewHolder holder, final int position) {
//getting the product of the specified position
Horse horse = horseList.get(position);
//binding the data with the viewholder views
holder.ViewWinPercent.setText(String.valueOf(horse.getWinPercentHorse()));
holder.imageView.setImageDrawable(mCtx.getResources().getDrawable(horse.getImgHorse()));
holder.ViewValueLine.setText(String.valueOf(horse.getValueOdds()));
holder.itemView.setTag(horse.getId());
holder.spinnerView.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
#Override
public void onItemSelected(AdapterView<?> adapterView, View view, int i, long l) {
// Update winPercent of item On selecting a spinner item
Toast.makeText(mCtx, "Spinner Selection =" + l + "item selected =" + position, Toast.LENGTH_SHORT).show();
//How to update the WinPercentHorse variable for this item in the horseList
//Then refresh the item notifyItemChange(position, object payload)?
}
#Override
public void onNothingSelected(AdapterView<?> adapterView) {
}
});
}
#Override
public int getItemCount() {
return horseList.size();
}
public void setHorseList(List<Horse> horseList) {
this.horseList = horseList;
notifyDataSetChanged();
}
}
class HorseViewHolder extends RecyclerView.ViewHolder {
TextView ViewWinPercent, ViewValueLine;
ImageView imageView;
Spinner spinnerView;
public HorseViewHolder(View itemView) {
super(itemView);
ViewWinPercent = itemView.findViewById(R.id.winPercentHorse);
ViewValueLine = itemView.findViewById(R.id.valueLine);
imageView = itemView.findViewById(R.id.imgHorse);
spinnerView=itemView.findViewById(R.id.spinner);
}
}
