分享个刚写好的 android 的 ListView 动态加载类，功能全而代码少。

 1     @Override
 2     public SimpleAdapter configSimpleAdapter() {
 3        //在这里配置 SimpleAdapter，再返回，默认返回null
 4         return null;
 5     }
 6 
 7     @Override
 8     public ArrayAdapter configArrayAdapter() {
 9        //在这里配置 ArrayAdapter
10         return null;
11     }
12 
13     @Override
14     public void configOnItemClick(AdapterView<?> parent, View view, int position, long id) {
15         // 在这里处理 listView的 点击事件
16     }
17 
18 
19     @Override
20     public void refreshData() {
21         //在这里处理 加载操作，无需再新建线程执行
22     }

 19  * Created by LinGuanHong on 2015/7/14.
 20  * 简介：
 21  *     该ListView 实现动态加载数据
 22  *     1,所有关键的操作使用接口，由用户自己定义，
 23  *           包括：数据适配器的配置、动态加载函数的配置、item点击接口;
 24  *     2,已经新建线程来执行动态函数。
 25  *     //3,提供一个默认的动态执行函数;
