我有一个Listview，我希望从我的MainActivity中获取该列表视图中单个项目的值...

    public class MainActivity extends Activity implements OnItemClickListener {
         ListView mylist;
        @Override
        protected void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
            setContentView(R.layout.activity_main);

            LayoutInflater i = LayoutInflater.from(this);

            ListView mylist=(ListView)findViewById(R.id.listexample);

            List<Item> items = new ArrayList<Item>();
            items.add(new Header(i, "Group","See More",R.drawable.ic_launcher));
            items.add(new EventItem(i, R.drawable.demoimage , R.drawable.demoimage ,R.drawable.demoimage ,R.drawable.demoimage ));




            MyListAdapter adapter = new MyListAdapter(this, items);
            mylist.setAdapter(adapter);
            mylist.setOnItemClickListener(this);
        }

        @Override
        public void onItemClick(AdapterView<?> arg0, View arg1, int arg2, long arg3) {

    //What will the Value here .....

        }

        TextView cat = (TextView) convertView
                .findViewById(R.id.header_catagory);
        cat.setText(catagory);

    //  cat.setOnClickListener(Header.this);

        TextView s_m = (TextView) convertView.findViewById(R.id.header_seemore);
        s_m.setText(see_more);

        ImageButton imb = (ImageButton) convertView
                .findViewById(R.id.header_imageButton1);

        imb.setBackgroundResource(image);
        return convertView;
