二级列表的简单用法

布局代码:

<ExpandableListView
   android:visibility="gone"
    android:id="@+id/pt_lv"
    android:descendantFocusability = "blocksDescendants"
    android:divider="@null"
    android:scrollbars="none"
    android:layout_width="match_parent"
    android:layout_height="wrap_content">
</ExpandableListView>

主页面代码:

  pt_lv = (ExpandableListView) view.findViewById(R.id.pt_lv);
carPersonUtils.setCarPersonInterface(new CarPersonInterface() {

                //请求数据成功
                @Override
                public void CarSuccess(final CarBean bean) {

                    list_shop = new ArrayList<Car_shop_Bean>();
                    list_shop_chiled = new ArrayList<List<Car_child_shop_Bean>>();
                    //添加进二级列表的 
for (int i = 0; i < data.size(); i++) {
    String sellerName = data.get(i).getSellerName();
    list_shop.add(new Car_shop_Bean(sellerName, false));

    List<CarBean.DataBean.ListBean> list = data.get(i).getList();

    ArrayList<Car_child_shop_Bean> car_shop_been = new ArrayList<>();

             for (CarBean.DataBean.ListBean childList : list) {
                  int num = childList.getNum();
                  float price = childList.getPrice();
                  String images = childList.getImages();
                  String title = childList.getTitle();
                  String[] split = images.toString().split("\\|");
                 car_shop_been.add(new Car_child_shop_Bean(title, num, price, split[0], false));
                   }
                     list_shop_chiled.add(car_shop_been);
                 }
//让他默认收回(并展示)
                    int count = pt_lv.getCount();
                    for (int i = 0; i < count; i++) {
                        pt_lv.expandGroup(i);
                    }
                    pt_lv.setGroupIndicator(null);
                }

  //不可视状态将刷新开启
    @Override
    public void onPause() {
        super.onPause();
        isFlag = true;
    }
    //得到焦点时的方法
    @Override
    public void onResume() {
        super.onResume();
        if(isFlag){
            initCarriage();
        }
