ListView应用------ListView控件显示List集合中的数据，并对Item响应选择事件(法一)

本例采用该类继承Activity+simpleAdapter实现的方式
这是天气预报的一个截图效果

/****************************************8
/*listData是一个List<Map<String,Object>>list的数据,里面有三组数据(今天,明天,后天),每组数据包括img1(天气图标一),img2(天气图标二),string(天气情况).每一组数据对一ListView的一行数据,只有取出数据后装载入map,再装入simpleadapter将对应的resID关联到R.id.img1,R.id.img2,R.id.textview.
实现思想如下:
Map<String,Object>map=new HashMap<String,Object>();
List<Map<String,Object>> list=new ArrayList<Map<String,Object>>();
map.put("weatherDay",weatherToday);
/icon1_ID是对webservice获取的soapObject对应图片的字符串解析后得到的resID,便于在R.drawable中查找对应的图片
//三天不同的天气情况对应的读图片字符串都不同
map.put("icon1", icon1_ID);/
map.put("icon2", icon2_ID);
list.add(map);

map=new HashMap<String,Object>();
map.put("weatherDay", weatherTomorrow);
map.put("icon1", icon1_ID);
map.put("icon2", icon2_ID);
list.add(map);

map=new HashMap<String,Object>();
map.put("weatherDay",weatherToday);
map.put("icon1", icon1_ID);
map.put("icon2", icon2_ID);
list.add(map);
