【核心代码】

listView= (ListView) this.findViewById(R.id.listview);
        List<HashMap<String,String>>data = new ArrayList<HashMap<String,String>>();
        UserService us = new UserService(this);
        List<User> users = us.getScrollDate(0, 10);
        for(User u : users){
         HashMap<String,String> map = new HashMap<String, String>();
         map.put("userid", String.valueOf(u.getUserid()));
         map.put("name", u.getName());
         map.put("age", String.valueOf(u.getAge()));
         data.add(map);
        }
        SimpleAdapter adapter = new SimpleAdapter(this,data,R.layout.useritem,new String[]{"userid","name","age"},new int[]{R.id.userid,R.id.name,R.id.age});
        
       listView.setAdapter(adapter);
        listView.setOnItemClickListener(new OnItemClickListener(){

   @SuppressWarnings("unchecked")
   @Override
   public void onItemClick(AdapterView<?> parent, View view,
     int position, long id) {
    ListView listView = (ListView)parent;
    HashMap<String, String> map = (HashMap<String, String>) listView.getItemAtPosition(position);
    String userid = map.get("userid");
    String name = map.get("name");
    String age = map.get("age");

//打开下一个activity
Intent i=new Intent();
//CurActivity 是当前activity, NextActivity 是要跳转至的activity
				    i.setClass(CurActivity.this,NextActivity.class);
				    i.putExtra("userid",userid);
				    startActivity(i);

   }
        });
