Increment counter with button click in recyclerview ( of cardview )

Question

I am working on app that using RecyclerView. I have a Button in each card that when clicked, will count the number of clicks and display it in a TextView in that particular card. The app crashes (Logic Error ) when I run it. What am I doing wrong ? ( I want to setcheck the check box true when counter = counter in Model )

public class MorAdapter extends RecyclerView.Adapter<MorAdapter.HViewholder> {

private ArrayList<ZekeritemModel> model=new ArrayList<>();





public MorAdapter(ArrayList<ZekeritemModel> models,Context context) {
    this.model = models;
}
@Override
public HViewholder onCreateViewHolder(@NonNull ViewGroup parent, int viewType) {
    LayoutInflater layoutInflater = LayoutInflater.from(parent.getContext());
    View v = layoutInflater.inflate(R.layout.mor_items, parent, false);


    return new HViewholder(v);
}




@Override
public void onBindViewHolder(@NonNull MorAdapter.HViewholder holder, int position) {


    holder.plusbtn.setOnClickListener(new View.OnClickListener() {
         int count =0;
        @Override
        public void onClick(View v) {
            count++;
            holder.plustext.setText(Integer.toString(count));
            if (count==model.get(position).getCounter()){
                holder.checkBox.setChecked(true);}
                           
        }
    });
}
@Override
public int getItemCount() {
    return model.size();
}

 class HViewholder extends RecyclerView.ViewHolder {
  TextView  plustext;
  CircleButton plusbtn;
  CheckBox checkBox;



     HViewholder(View itemView) {
        super(itemView);
        plusbtn=itemView.findViewById(R.id.pluss);
        plustext=itemView.findViewById(R.id.plustext);
        checkBox=itemView.findViewById(R.id.checkk);
    }
}

}

Answer 1

add currentCount property to your model ZekeritemModel so your model became

public class ZekeritemModel {
.... your code 
.... 
 int currentCount = 0; 
// add your getter and setter ..

}

change your onBind to

@Override
public void onBindViewHolder(@NonNull MorAdapter.HViewholder holder, int position) {
    // get current item
    final ZekeritemModel item = model.get(position);
    int count = item.getCurrentCount();
    // set value of counter inside textview
    holder.plustext.setText(Integer.toString(count));

    holder.plusbtn.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            count++;
            item.setCurrentCount(count);
            holder.plustext.setText(Integer.toString(count));
            if (count==model.get(position).getCounter()){
                holder.checkBox.setChecked(true);}
                           
        }
    });
}
