android中，用SimpleAdapter创建有自己布局的listView，以及listView的修改更新notifyDataSetChanged()的使用。

做一个具有自己布局设置的listView

setlistLeft = (ListView)findViewById(R.id.listleft);

adapterL = new SimpleAdapter(this.getContext(), getData(),
R.layout.leftview,new String[]{"titleL","infoL"},new int[]{R.id.titleL,R.id.infoL});
setlistLeft.setAdapter(adapterL);

 public List<Map<String,String>> getData() {       
            List<Map<String,String>> list = new ArrayList<Map<String,String>>() ;  
           
            Map<String,String> map_balance = new HashMap<String,String>();
            map_balance.put("titleL", getContext().getString(R.string.set_balance));
            map_balance.put("infoL", "自动");
            list.add(map_balance);

      return list;
}

修改listView中第二项的内容为string

public void UpdateList(int selectedItem, String string)
        {    SimpleAdapter la = adapterL;   
            HashMap<String, Object> map = (HashMap<String, Object>)la.getItem(selectedItem);                  
            map.put("infoL", string);
               
           la.notifyDataSetChanged();
        }
