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(); }
