Can't get Selected Item Index in custom ArrayAdapter on my ListView

Question

I have problem with my Android project, because I can't get selected item index from my List with my own ArrayAdapter. I've tried few examples from tutorials but they don't work. What is the solution?

Adapter

public class myProductAdapter extends ArrayAdapter<myProductsGroup> {

    private List<myProductsGroup> productList;
    private Context context;

    public myProductAdapter(List<myProductsGroup> productList, Context ctx) {
        super(ctx, R.layout.list_products_row, productList);
        this.productList = productList;
        this.context = ctx;
    }

    @Override
    public int getCount() {
    return productList.size();
    }

    /*
    public void onClick(View v) {
        int position = Integer.parseInt((String) v.getTag());

        OrderFirstGridPage.setSelectedItem(position);             
    }
    */

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

        if (convertView == null) {
            LayoutInflater inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
            convertView = inflater.inflate(R.layout.list_products_row, parent, false);
        }
            TextView tv = (TextView) convertView.findViewById(R.id.title);
            tv.setTag(""+position);
            TextView distView = (TextView) convertView.findViewById(R.id.description);
            distView.setTag(""+position);
            tv.setText("aa");
        return convertView;
    }
}

In activity

lv = (ListView) findViewById(R.id.listView1);
lv.setAdapter(new myProductAdapter(setupArrayProductList((ArrayList<myProduct>) ProductList), OrderFirstGridPage.this));
lv.setSelector(R.drawable.selector_for_position_list);

Answer 1

Try to use this line of code:

    lv = (ListView) findViewById(R.id.listView1);
    lv.setAdapter(new myProductAdapter(setupArrayProductList((ArrayList<myProduct>) ProductList), OrderFirstGridPage.this));
    lv.setSelector(R.drawable.selector_for_position_list);      

 lv.setOnItemClickListener(new OnItemClickListener() {

                                            @Override
                                            public void onItemClick(AdapterView<?> parent,
                                                    View view, int position, long id) {
                                                Log.d("My POSITION",""+position);

                                            }
                                        });

Hope you will get the exact position from selected listview. If you get any problem, please inform me. Hope this will works.

You need to implement AdapterView.OnItemClickListener: http://developer.android.com/reference/android/widget/AdapterView.OnItemClickListener.html

public abstract void onItemClick (AdapterView<?> parent, View view, int position, long id)

There, you'll get the index of each item.

You just have to set that listener to your list:

lv.setOnItemClickListener(yourListener);
