android: how to get the gridview position while its checkbox item is checked?

I have a custom gridview with checkbox, imageview and textview. In the gridviewAdapter.getView(), i have used rows and holder to initialise the values for checkbox, imageview and textview. Now when I click on checkbox, I need to fetch the position of that gridview item so i can move the image from its position to another position in a gridview.

public View getView(int position, View convertView, ViewGroup parent) {
    View row = convertView;
    ViewHolder holder = null;
    if (row == null) {
        LayoutInflater inflater = ((Activity) context).getLayoutInflater();
        row = inflater.inflate(layoutResourceId, parent, false);
        holder = new ViewHolder();
        holder.imageTitle = (TextView) row.findViewById(R.id.textView);
        holder.image = (ImageView) row.findViewById(R.id.imageView);
        holder.cb=(CheckBox)row.findViewById(R.id.checkBox);

            holder.cb.setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View v) {
                    //here with this checkbox which just got clicked,
                    // i want to access its gridview position or holder index
                    // so i can get access to the image

                }
            });
        row.setTag(holder);
    } else {
        holder = (ViewHolder) row.getTag();
    }

    ImageItem item = (ImageItem)dataArraylist.get(position);
    holder.imageTitle.setText(item.getTitle());
    holder.image.setImageBitmap(item.getImage());
   // holder.cb.setChecked(item.isSelected());

    return row;
}
    public static class ViewHolder {
    public TextView imageTitle;
    public ImageView image;
    public CheckBox cb;
}
