        }
    }
}

4:

MessageEvent类里
public class MessageEvent {
    private boolean checked;

    public boolean isChecked() {
        return checked;
    }

    public void setChecked(boolean checked) {
        this.checked = checked;
    }
}


5:
PriceAndCountEvent 类里
public class PriceAndCountEvent {
    private int price;
    private int count;

    public int getPrice() {
        return price;
    }

    public void setPrice(int price) {
        this.price = price;
    }

    public int getCount() {
        return count;
    }

    public void setCount(int count) {
        this.count = count;
    }
}

6:model层 里面有两个 非别是一个接口和一个类
IMainModedl接口
public interface IMainModedl {
    public void getGoods(OnNetListener<GoosBean> onNetListener);

}
MainModel类需要继承IMainModel接口
public class MainModel implements IMainModedl{
    private Handler handler = new Handler(Looper.getMainLooper());
    @Override
    public void getGoods( final OnNetListener<GoosBean> onNetListener) {
        HttpUtils.getHttpUtils().doGet(Api.url, new Callback() {
            @Override
            public void onFailure(Call call, IOException e) {

            }

            @Override
            public void onResponse(Call call, Response response) throws IOException {
                String string = response.body().string();
                final GoosBean goosBean = new Gson().fromJson(string, GoosBean.class);
                handler.post(new Runnable() {
                    @Override
                    public void run() {
                        onNetListener.onSuccess(goosBean);
                    }
                });
            }
        });
    }
}

7定义网络请求层
分为三个
7-1:
public interface Api {
    public static final String url = "http://result.eolinker.com/iYXEPGn4e9c6dafce6e5cdd23287d2bb136ee7e9194d3e9?uri=evaluation";
}
7-2:HttpUtils
public class HttpUtils {
    private static volatile HttpUtils httpUtils;
    private final OkHttpClient client;

    private HttpUtils() {
        HttpLoggingInterceptor logging = new HttpLoggingInterceptor();
        logging.setLevel(HttpLoggingInterceptor.Level.BODY);
        client = new OkHttpClient.Builder()
                .addInterceptor(logging)
                .build();
    }

    public static HttpUtils getHttpUtils() {
        if (httpUtils == null) {
            synchronized (HttpUtils.class) {
                if (httpUtils == null) {
                    httpUtils = new HttpUtils();
                }
            }
        }
        return httpUtils;
    }

    /**
     * GET请求
     *
     * @param url
     * @param callback
     */
    public void doGet(String url, Callback callback) {
        Request request = new Request.Builder().url(url).build();
        client.newCall(request).enqueue(callback);
    }
}
7-3:OnNetListener是一个接口
public interface OnNetListener<T> {
    public void onSuccess(T t);

    public void onFailure(Exception e);
}

8:presenter类 定义
MainPresenter类
public class MainPresenter {

    private final MainModel imainModel;
    private final IMainActivity iMainActivity;

    public MainPresenter(IMainActivity iMainActivity) {
        this.iMainActivity = iMainActivity;
        imainModel = new MainModel();
    }


    public void getGoods() {
        imainModel.getGoods(new OnNetListener<GoosBean>() {
            @Override
            public void onSuccess(GoosBean goosBean) {
                //List<GoosBean.DataBean> groupList, List<List<GoosBean.DataBean.DatasBean>> childList
                List<GoosBean.DataBean> dataBean = goosBean.getData();
                List<List<GoosBean.DataBean.DatasBean>> childList = new ArrayList<List<GoosBean.DataBean.DatasBean>>();
                for (int i = 0; i < dataBean.size(); i++) {
                    List<GoosBean.DataBean.DatasBean> datas = dataBean.get(i).getDatas();
                    childList.add(datas);
                }
                iMainActivity.showList(dataBean, childList);
            }

            @Override
            public void onFailure(Exception e) {

            }
        });

    }
}


9:view层 一个接口一个类:
IMainActivity接口
public interface IMainActivity {
    public void showList(List<GoosBean.DataBean> groupList, List<List<GoosBean.DataBean.DatasBean>> childList);
}
MainActivity类继承IMainActivity接口
public class MainActivity extends AppCompatActivity implements IMainActivity{

    private ExpandableListView mElv;
    private CheckBox mCheckbox2;
    /**
     * 0
     */
    private TextView mTvPrice;
    /**
     * 结算(0)
     */
    private TextView mTvNum;
    private int totalCount;
    private int totalPrice;
    private MyAdapter adapter;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        EventBus.getDefault().register(this);
        initView();
        new MainPresenter(this).getGoods();
        mCheckbox2.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                adapter.selectAllGroup(mCheckbox2.isChecked());
            }
        });
    }

    @Override
    protected void onDestroy() {
        super.onDestroy();
        EventBus.getDefault().unregister(this);

    }

    private void initView() {
        mElv = (ExpandableListView) findViewById(R.id.elv);
        mCheckbox2 = (CheckBox) findViewById(R.id.checkbox2);
        mTvPrice = (TextView) findViewById(R.id.tv_price);
        mTvNum = (TextView) findViewById(R.id.tv_num);
    }



    @Override
    public void showList(List<GoosBean.DataBean> groupList, List<List<GoosBean.DataBean.DatasBean>> childList) {
        adapter = new MyAdapter(this, groupList, childList);
        mElv.setAdapter(adapter);
        mElv.setGroupIndicator(null);
        //默认让其全部展开
        for (int i = 0; i < groupList.size(); i++) {
            mElv.expandGroup(i);
        }
    }

    @Subscribe
    public void onMessageEvent(MessageEvent event) {
        mCheckbox2.setChecked(event.isChecked());
    }
    @Subscribe
    public void onMessageEvent(PriceAndCountEvent event) {
        totalCount += event.getCount();
        totalPrice += event.getPrice();
        mTvNum.setText("结算(" + totalCount + ")");
        mTvPrice.setText(totalPrice + "");
    }
}

10:适配器 也是最重要的一个类
MyAdapter继承basexEpandableListAdapter
public class MyAdapter extends BaseExpandableListAdapter{


    private Context context;
    private List<GoosBean.DataBean> groupList;
    private List<List<GoosBean.DataBean.DatasBean>> childList;
    private final LayoutInflater inflater;

    public MyAdapter(Context context, List<GoosBean.DataBean> groupList, List<List<GoosBean.DataBean.DatasBean>> childList) {
        this.context = context;
        this.groupList = groupList;
        this.childList = childList;
        inflater = LayoutInflater.from(context);
    }

    @Override
    public int getGroupCount() {
        return groupList.size();
    }

    @Override
    public int getChildrenCount(int i) {
        return childList.get(i).size();
    }

    @Override
    public Object getGroup(int i) {
        return groupList.get(i);
    }

    @Override
    public Object getChild(int i, int i1) {
        return childList.get(i).get(i1);
    }

    @Override
    public long getGroupId(int i) {
        return i;
    }

    @Override
    public long getChildId(int i, int i1) {
        return i1;
    }

    @Override
    public boolean hasStableIds() {
        return false;
    }

    @Override
    public View getGroupView(final int groupPosition, boolean isExpanded, View convertView, ViewGroup parent) {
        View view;
        final GroupViewHolder holder;
        if (convertView == null) {
            holder = new GroupViewHolder();
            view = inflater.inflate(R.layout.item_parent_market, null);
            holder.cbGroup = view.findViewById(R.id.cb_parent);

        } else {

            holder = (GroupViewHolder) view.getTag();
        }
        final GoosBean.DataBean dataBean = groupList.get(groupPosition);
        holder.cbGroup.setChecked(dataBean.isChecked());
        holder.tv_number.setText(dataBean.getTitle());

        //给holder.cbGroup设置点击事件
        holder.cbGroup.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
               /* if (holder.cbGroup.isChecked()) {
                    //点击的一级列表中的checkbox为选中状态
                    selectChildAll(groupPosition, true);
                } else {

                dataBean.setChecked(holder.cbGroup.isChecked());
                PriceAndCountEvent priceAndCountEvent = computePriceAndCount(holder.cbGroup.isChecked(), groupPosition);
