public class AlphabetListDemo extends Activity {

    //String of alphabets //

    String[] alphabts = {"A","B","C","D","E","F","G","H","I","J","K","L"};

    ListView L1, L2;

    myAdapter myadp;

    myAdapter2 myadp2;

    String prod_arr[] = {};

 

    @Override

    public void onCreate(Bundle savedInstanceState) {

        super.onCreate(savedInstanceState);

        setContentView(R.layout.main);

 

        L1 = (ListView)findViewById(R.id.list1);

        L2 = (ListView)findViewById(R.id.list2);

 

        myadp = new myAdapter(this,alphabts);

        L2.setAdapter(myadp);

 

        // initial populating //

        setProducts(0);   

 

        L2.setOnItemClickListener(new OnItemClickListener(){

            @Override

            public void onItemClick(AdapterView<?> arg0, View arg1, int arg2,

                    long arg3) {

                setProducts(arg2);

            }

        });

 

    }

 

    public void setProducts(int number){

        prod_arr = new String[25];

        // adding some dummy data //

        for(int i = 0; i < 25 ; i++){

            prod_arr[i] = "Product : " + alphabts[number] + i;

        }

        //setting the adapter in listview //

         myadp2 = new myAdapter2(AlphabetListDemo.this,prod_arr);

         L1.setAdapter(myadp2);

    }

 

    class myAdapter extends ArrayAdapter<String>

    {

       TextView label;

       ImageView image;

       View row;

       public myAdapter(Context context,String[] arr)

       {

            super(context, android.R.layout.simple_list_item_1, arr);

       }       

 

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

        {

               try{

                    LayoutInflater inflater=getLayoutInflater();

                    row = inflater.inflate(R.layout.lv_rows, parent, false);

                    label = (TextView)row.findViewById(R.id.item_title);

                    label.setText(alphabts[position]);

                    label.setTextColor(Color.YELLOW);

               }catch(Exception e){

 

               }

            return row;

        }

    }

    // adapter for second list.....

    class myAdapter2 extends ArrayAdapter<String>

    {

       TextView label;

       ImageView image;

       View row;

       public myAdapter2(Context context,String[] arr)

       {

            super(context, android.R.layout.simple_list_item_1, arr);

       }       

 

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