I am not sure if this is a neat way. But the below code solved my problem. Even in the below code, the setOnCheckChangeListener() was getting called (read falsely triggered) on scrolling of the list. The task was to maintain a list of items that have been selected by the user. So when there is a trigger, I first refer my list and only add an item if it was not already present in the list, else I ignore the callback.

@Override
public View getView(final int position, View convertView, final ViewGroup parent) {


    MenuViewHolder menuViewHolder = null;
    MenuView item = getItem(position);


    LayoutInflater inflater = ((Activity) context).getLayoutInflater();

    convertView = inflater.inflate(R.layout.food_menu_list_layout, null);

    TextView textView = ((TextView) convertView.findViewById(R.id.menu_item_entry));
    TextView price = (TextView) convertView.findViewById(R.id.price);
    CheckBox ordered = (CheckBox) convertView.findViewById(R.id.checkBox);

    menuViewHolder = new MenuViewHolder(textView, price, ordered);

    menuViewHolder.dishName.setText(menuViewList.get(position).getItemname());
    menuViewHolder.price.setText("$" + menuViewList.get(position).getPrice());
    menuViewHolder.ordered.setChecked(menuViewList.get(position).isSelected());

    menuViewHolder.ordered.setOnCheckedChangeListener(null);


    menuViewHolder.ordered.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {

        @Override
        public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {

            MenuView checkedItem = menuViewList.get(position);
            if (buttonView.isChecked()) {

                //add item only if not already added
                if (!checkedItem.isSelected()) {
                    MainActivity.menuViews.add(checkedItem);
                    checkedItem.setSelected(buttonView.isChecked());
                }       


            } else {

                //remove only if already added
                if (checkedItem.isSelected()){
                    MainActivity.menuViews.remove(checkedItem);
                    checkedItem.setSelected(buttonView.isChecked());
                }                    
            }

            ((MainActivity) context).displayCurrentSelectionAmt();
        }
    });


return convertView;

}
