I have added arraylist in arrayadapter which contains objects each consists of two elements/items, I have successfully set that adapter for setListAdapter, now i want to get those items in setOnItemClickListener of listview.

//tweets - arraylist which contains object
TweetListAdaptor adaptor = new TweetListAdaptor(this,R.layout.list_item, tweets);       
setListAdapter(adaptor); 
  ListView lv = getListView();
  lv.setTextFilterEnabled(true);
  lv.setOnItemClickListener(new OnItemClickListener() 
  {
    public void onItemClick(AdapterView<?> parent, View view,int position, long id) 
    {
         //here i want to get the items             
    }
  });
