Android 关于ExpandableListView刷新问题的解决方法

ExpandableListView vList = (ExpandableListView) this.findViewById(R.id.list);EListAdapter adapter = new EListAdapter(getApplicationContext(), list); //list 是数据源vList.setAdapter(adapter);//适配器就不写了, 都懂的class EListAdapter extends BaseExpandableListAdapter {}

class EListAdapter extends BaseExpandableListAdapter {  public EListAdapter(Context context, List<T> list) {    this.list = list;    this.context = context;    handler = new Handler(){      @Override      public void handleMessage(Message msg) {       notifyDataSetChanged();       super.handleMessage(msg);      }    };  }    public void refresh() {    handler.sendMessage(new Message());  }}

vList.collapseGroup(groupPosition);vList.expandGroup(groupPosition);
