// binding array to ListAdapter 
setListAdapter(new ArrayAdapter<String> 
      (this,android.R.layout.simple_expandable_list_item_1,result)); 
    selection = (TextView)findViewById(R.id.selection); 


// listening to single list item on click 
protected void onListItemClick(ListView l,View v, int position, long id){ 
    super.onListItemClick(l, v, position, id); 
// selected item 
String product = result[position]; 
Intent ii = new Intent(getApplicationContext(),Desire.class); 
// sending data to new activity 
ii.putExtra("product", product); 
startActivity(ii); 
};
