Android Custom ListView - how to prevent the ListView adapter from automatically updating (updating) when scrolling

try setting the number as a view.setTag tag (number) and get it in OnItemClickListener:

listView.setOnItemClickListener(new OnItemClickListener() {         
    @Override
    public void onItemClick(AdapterView<?> arg0, View view,
                            int position, long arg3) {
        if (position > 0 && position < mProducts.alternatives.size() + 1){
        int number = (Integer)view.getTag();
        }
    }
});
