ListView用自定义适配器绑定数据

//自定义适配器
private void show2() {
List<Person> persons=service.getScrollData(0, 20);//需要绑定的数据，getScrollData代码在下方

PersonAdapter adapter=new PersonAdapter(getApplicationContext(), persons, R.layout.item); listView.setAdapter(adapter); }

* 分页获取记录
* @param offset 跳过前面多少条记录
* @param maxResult 每页显示多少条记录
* @return
