listview传值到另外Activity

现在做了一个ListView，里面的值是用cursor提取数据库的，现在想点击listview以后页面进行跳转，并且在新的activity里显示被点击的listview的数据，我的listview有很多列，所以希望数据能分开来放，现在完全没有一点头绪，查了资料也没有

DataListActivity.class
public class DataListActivity extends ActionBarActivity implements AdapterView.OnItemClickListener {
    ListView listView;
    SQLiteDatabase sqLiteDatabase;
    DBHelper dbHelper;
    Cursor cursor;
    ListDataAdapter listDataAdapter;



    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.data_list_layout);

        listView = (ListView) findViewById(R.id.list_view);

        listDataAdapter = new ListDataAdapter(getApplicationContext(),R.layout.reporter_my_request);

        listView.setAdapter(listDataAdapter);
        listView.setOnItemClickListener(this);

        dbHelper = new DBHelper(getApplicationContext());
        sqLiteDatabase = dbHelper.getReadableDatabase();
        cursor = dbHelper.getInformation(sqLiteDatabase);
        if(cursor.moveToFirst())
        {
            do {
                String id,name,title,department,category;
                id = cursor.getString(0);
                name = cursor.getString(1);
                title= cursor.getString(2);
                department=cursor.getString(3);
                category=cursor.getString(4);
     //           description=cursor.getString(4);

                DataProvider dataProvider=new DataProvider(id,name,title,department,category);

                listDataAdapter.add(dataProvider);




            }while (cursor.moveToNext());

            }
        dbHelper.close();

        }

    @Override
    public void onItemClick(AdapterView parent, View view, int position, long id) {





        Object o =parent.getItemAtPosition(position);
        Toast.makeText(this,"",Toast.LENGTH_LONG).show();

        Intent intent = new Intent(DataListActivity.this,RequestListInfo.class);




        startActivity(intent);




    }
}

ListDataAdapter.class
public class ListDataAdapter extends ArrayAdapter {
    List list = new ArrayList();
    public ListDataAdapter(Context context, int resource) {
        super(context, resource);

    }


    static class LayoutHandler

    }

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

        View row = convertView;
        LayoutHandler layoutHandler;
        if(row == null)
        {
            LayoutInflater layoutInflater = (LayoutInflater)this.getContext().getSystemService(Context.LAYOUT_INFLATER_SERVICE);
            row = layoutInflater.inflate(R.layout.reporter_my_request,parent,false);
            layoutHandler = new LayoutHandler();
            layoutHandler.ID   = (TextView) row.findViewById(R.id.text_id);
            layoutHandler.NAME = (TextView)row.findViewById(R.id.text_name);

            row.setTag(layoutHandler);

        }
        else
        {
            layoutHandler = (LayoutHandler)row.getTag();
        }
        DataProvider dataProvider = (DataProvider)this.getItem(position);
        layoutHandler.ID.setText(dataProvider.getId());
        layoutHandler.NAME.setText(dataProvider.getName());
        layoutHandler.TITLE.setText(dataProvider.getTitle());
        layoutHandler.DEPARTMENT.setText(dataProvider.getDepartment());
        layoutHandler.CATEGORY.setText(dataProvider.getCategory());
  //      layoutHandler.DESCRIPTION.setText(dataProvider.getDescription());

        return row;
    }
}

DataProvider.class
public class DataProvider {

    private String id;




    public String getId() {
        return id;
