Question

我在列表视图中有一个微调器，因此当从哪个列表项中选择微调器值时如何获取列表项的值。

请回答此问题

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

    ViewHolderItem viewHolder;
    if(convertView==null){
        inflater = ((Activity) context).getLayoutInflater();
        convertView = inflater.inflate(R.layout.cart_item, parent, false);
        viewHolder = new ViewHolderItem();
        viewHolder.toptext = (TextView) convertView.findViewById(R.id.cartname);
        viewHolder.prc = (TextView) convertView.findViewById(R.id.textView76);
        viewHolder.shp = (TextView) convertView.findViewById(R.id.textView77);
        viewHolder.subtotal = (TextView) convertView.findViewById(R.id.textView79);
        viewHolder.img = (ImageView) convertView.findViewById(R.id.imageView7);
        viewHolder.spinner = (Spinner)convertView.findViewById(R.id.spinner);
        convertView.setTag(viewHolder);

    }else{
        viewHolder = (ViewHolderItem) convertView.getTag();
    }

    final CartResponse response = getItem(position);
    int subtotal1=0;
    mydb = new DBHelper(getContext());

    if(response != null) {
        ArrayAdapter<CharSequence> adapter = ArrayAdapter.createFromResource(getContext(),
                R.array.qty, android.R.layout.simple_spinner_item);
        adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
        viewHolder.spinner.setAdapter(adapter);
        viewHolder.spinner.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {

            @Override
            public void onItemSelected(AdapterView<?> parent, View view,
                                       int pos, long id) {
                response.getid();
                if(mydb.updateCart(Integer.parseInt(response.getid()),pos)) {

                    Toast.makeText(getContext(),"updated", Toast.LENGTH_SHORT).show();
                }

            }

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

            }
        });
        subtotal1=Integer.parseInt(response.getPrice()) + Integer.parseInt(response.getShipping());
        viewHolder.toptext.setText(response.getPname());
        viewHolder.prc.setText("Rs."+response.getPrice());
        //Log.d("key",""+response.getPrice());
        viewHolder.shp.setText("Rs."+response.getShipping());
        viewHolder.subtotal.setText("Sub total Rs."+subtotal1);
        Picasso.get().load("https://www.exmple.com/photos/"+response.getPhoto()+".png").placeholder(R.drawable.placeholder).memoryPolicy(MemoryPolicy.NO_CACHE).networkPolicy(NetworkPolicy.NO_CACHE).into(viewHolder.img);
    }

所以我想要列表中项目的值，我可以从中选择微调框，也可以选择微调框值

如何获取在列表视图中选择了哪个列表项微调器
