OnClickListener with RecyclerView

Hello,

Im doing the Android Activity Lifecycle and I tried to do it with recyclerview. However Im not sure how to add a onclicklistener to a specific element. There are two buttons and when we click them, we want the number counter to go up and down.

Since we need access to the element's position, I put an onclick listener under the bind method:

    @Override
    public void onBindViewHolder(final listViewHolder holder, final int position) {
        holder.bind(mHoles[position]);
        holder.mRemoveStrokeButton.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                int updatedStrokeCount = mHoles[position].getStrokeCount() - 1;
                if (updatedStrokeCount < 0) updatedStrokeCount = 0;
                mHoles[position].setStrokeCount(updatedStrokeCount);
                holder.mStrokeCount.setText(updatedStrokeCount + "");
            }
        });

        holder.mAddStrokeCount.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                int updatedStrokeCount = mHoles[position].getStrokeCount() + 1;
                mHoles[position].setStrokeCount(updatedStrokeCount);
                holder.mStrokeCount.setText(updatedStrokeCount + "");
            }
        });
    }

It seems logical but there's probably more to it as my app keeps crashing

Thanks,

Kevin
