Spinner conflicts with Checkbox inside a ListView - Why?

Question

I'm trying to find out why spinner is conflicting with checkBox inside a listView. If I comment the spinner lines, the checkBox listener works fine, I can select it, check if is selected and delete the row of the List. If I let the spinner declaration, as it is in the code below, the listener works, I can select the checkBox but when I try to get the selected Item (at checkToDelete method) the return of the selected checkBox is always empty (like there is nothing selected). I need the spinner to check the quantity of items and the checkBox to delete the row.

Anyway, I've been researching a solution for 2 days and wouldn't like to let this problem go before know what is going on and prevent future mistakes. One possible solution I found is to avoid the use of spinner and instead use a button with AlertDialog

Does anyone know what I'm missing here?

Answer 1

    private List<Boolean> mCheckList;

    @Override
    public View getView(final int position,View convertView, ViewGroup viewGroup) {
        LayoutInflater inflater = (LayoutInflater) context
            .getSystemService(Context.LAYOUT_INFLATER_SERVICE);

        final ViewHolder holder;
        if (convertView == null) {
            holder = new ViewHolder();
            convertView = inflater.inflate(R.layout.menu_itens, null);

            holder.textview = (TextView) convertView.findViewById(R.id.item);     
            holder.imageView = (ImageView) convertView.findViewById(R.id.itemImage);
            holder.checkBox = (CheckBox) convertView.findViewById(R.id.check);
            holder.checkBox.setOnCheckedChangeListener(new OnCheckedChangeListener() {
                @Override 
                public void onCheckedChanged(CompoundButton buttonView,
                    boolean isChecked) {               
                    mCheckList.set(position, isChecked);
                }            
            });

            holder.spinner = (Spinner) convertView.findViewById(R.id.quantity);
            holder.spinner.setAdapter(spinnerAdapterArray[position]);
            holder.spinner.setOnItemSelectedListener(new OnItemSelectedListener() {

                @Override
                public void onItemSelected(AdapterView<?> parent, View view,
                        int pos, long id) {
                    //Listener options      
                }

                @Override
                public void onNothingSelected(AdapterView<?> parent) {
                    // TODO Auto-generated method stub              
                }           
            });

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

        String itemName = MENU_ITEM.get(position);
        holder.textview.setText(itemName);
        holder.checkbox.setChecked(mCheckList.get(position));

        return convertView;
    }

    public List<Integer> checkListToDelete() {

        List<Integer> aux = new ArrayList<Integer>();   
        for(int i=0; i<MENU_SIZE; i++){
            System.out.println(mCheckList.get(i));
            if(mCheckList.get(i)){
                aux.add(i);
            }

            mCheckList.set(i, false);
        }

        notifyDataSetChanged();
        return aux; 
    }

    class ViewHolder {
        TextView textview;
        ImageView imageview;
        Spinner spinner;
        CheckBox checkbox;
    }
