这篇是我刚接触安卓半个月写的 不推荐看 写的太臭了 这会在实习 等我有空改改
先上张图让大家看一看布局的方式
示意图上写的非常清楚了，横向listview里边再加一个横向的scrollview，需要注意的就是触摸事件的分发，我是通过ev.getY来判断高度来区别响应ListView本身的滑动还是ScrollView的滑动。
在这里我只是分点的把一些讲一下，看完再去看程序源码绝对轻松简单。
首先，你得有全国的省市的ID和名字，通过城市ID来从API获取天气数据
http://blog.csdn.net/d_dmelon/article/details/51361416
这本身就是个Activity，可以用startActivityforResult来启动，并且返回城市的Name和ID，通过id访问接口，获取该城市的天气情况。
然后就是怎么获取天气，我用的是这个接口，地址最后边的数字是城市id，北京的ID是101010100，如下
http://wthrcdn.etouch.cn/weather_mini?citykey=101010100
数据如下：

资源文件的resID Int型 和 天气情况的文字描述 String型。
所以data应该是个HashMap
HashMap<String,Object> item = new HashMap<String,Object>();
item.put("ftype",Rfirpng);// String ,Int
item.put("stype",Rsecpng);
item.put("ttype",Rthrpng);
item.put("fotype",Rfoupng);
item.put("fitype",Rfifpng);
item.put("name",strName);
item.put("ID",strID);
item.put("wendu",wendu);//String ,String
item.put("fengxiang",fengxiang);
item.put("ganmao",ganmao);
item.put("finfo",finfo);
item.put("sinfo",sinfo);
item.put("tinfo",tinfo);
item.put("foinfo",foinfo);
item.put("fiinfo",fiinfo);
mainList.add(item);

,R.id.firdayinfo,R.id.secdayinfo,R.id.thrdayinfo,R.id.foudayinfo,R.id.fifdayinfo};
mainAdapter = new SimpleAdapter(this,mainList,R.layout.weather,Keys,Ids);
// mAdapter = new HorizontalSimpleAdapter(this,mainList,R.layout.weather,Keys,Ids);
mainListView.setAdapter(mainAdapter);
// mainListView.setAdapter(mAdapter);1234567891012345678910恩恩，到这里就差不多能显示了，但天气预报不仅仅如此，看到我上边贴出来的代码里 saveListData这个函数，是不是很奇怪啊，这就是接下来我要说的，通过SharedPreferences来保存天气信息和是否第一次进入(如果要扩展，以后做过第一次进入的引导界面也是OK的)。
那么到底要保存哪些信息？
1是Json解析出来我们要显示的图片的resID和文字描述。
2是是否第一次进入，布尔值，如果第一次进入默认网络请求加载北京市的城市天气
3是上次我们申请刷新天气的时间，如果没有这个判断，你过几天再登进去看就是过时的信息啦哈哈
public void saveListData(){ //保存数据
SharedPreferences.Editor editor = getSharedPreferences("ArrayData",MODE_PRIVATE).edit();
SharedPreferences getData = getSharedPreferences("ArrayData",MODE_PRIVATE);
// int oldSize =getData.getInt("NUMBER",0);
editor.putInt("NUMBER",mainList.size());//已有的Item数目
for(int i=0;i<mainList.size();i++){ //把图片的R.ID存进去
editor.putInt("Item"+i+"ftype",(int)mainList.get(i).get("ftype"));
editor.putInt("Item"+i+"stype",(int)mainList.get(i).get("stype"));
editor.putInt("Item"+i+"ttype",(int)mainList.get(i).get("ttype"));
