private List<Navi> mRouteList;

1. 设置Adapter

private void initData() {    mRouteList = new ArrayList
     
      ();    mRouteList.clear();    mAdapter = new CarRouteAdapter(getActivity(), mRouteList);    mListView.setAdapter(mAdapter);}
     

2. 获取数据，刷新listview

 

private void updateRoutes(List
     
       listOfResult) {
    　　mRouteList.clear();　　mRouteList = CarUtils.formatNaviRoutes(listOfResult);　　mAdapter.notifyDataSetChanged(); }
     

发现这样做，listview的数据已经发生变化，但是就是没有更新。

解决如下：

private void updateRoutes(List
     
       listOfResult) {　　mRouteList.clear();　　// mRouteList = CarUtils.formatNaviRoutes(listOfResult);    mRouteList.addAll(CarUtils.formatNaviRoutes(listOfResult));　　mAdapter.notifyDataSetChanged();}
