这里是二级列表的布局

<?xml version="1.0" encoding="utf-8"?><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"    android:layout_width="match_parent"    android:layout_height="match_parent"    android:background="@android:color/darker_gray"    android:gravity="center_vertical"    android:orientation="horizontal">    <CheckBox        android:id="@+id/cb_child"        android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:layout_marginBottom="30dp"        android:layout_marginLeft="40dp"        android:layout_marginTop="30dp"        android:focusable="false" />    <LinearLayout        android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:orientation="vertical">        <TextView            android:id="@+id/tv_tel"            android:layout_width="wrap_content"            android:layout_height="wrap_content"            android:layout_marginLeft="20dp"            android:text="iphone6" />        <TextView            android:id="@+id/tv_content"            android:layout_width="wrap_content"            android:layout_height="wrap_content"            android:layout_marginLeft="20dp"            android:text="什么手机" />        <TextView            android:id="@+id/tv_time"            android:layout_width="wrap_content"            android:layout_height="wrap_content"            android:layout_marginLeft="20dp"            android:text="2016-12-10" />    </LinearLayout>    <LinearLayout        android:layout_width="match_parent"        android:layout_height="wrap_content"        android:layout_weight="1"        android:orientation="vertical">        <TextView            android:id="@+id/tv_pri"            android:layout_width="wrap_content"            android:layout_height="wrap_content"            android:text="¥3000.00" />        <LinearLayout            android:layout_width="match_parent"            android:layout_height="wrap_content"            android:gravity="center_vertical">            <ImageView                android:id="@+id/iv_del"                android:layout_width="20dp"                android:layout_height="20dp"                android:src="@drawable/shopcart_minus_red" />            <TextView                android:id="@+id/tv_num"                android:layout_width="wrap_content"                android:layout_height="wrap_content"                android:layout_marginLeft="5dp"                android:background="@drawable/shopcart_add_btn"                android:paddingBottom="2dp"                android:paddingLeft="20dp"                android:paddingRight="20dp"                android:paddingTop="2dp"                android:text="1" />            <ImageView                android:id="@+id/iv_add"                android:layout_width="20dp"                android:layout_height="20dp"                android:layout_marginLeft="5dp"                android:src="@drawable/shopcart_add_red" />        </LinearLayout>    </LinearLayout>    <TextView        android:id="@+id/tv_del"        android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:text="删除" /></LinearLayout>

这里是MainActivity

public class MainActivity extends AppCompatActivity implements IMainActivity {    private ExpandableListView mElv;    private CheckBox mCheckbox2;    /**     * 0     */    private TextView mTvPrice;    /**     * 结算(0)     */    private TextView mTvNum;    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.changeAllListCbState(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);        }    }

MainActivity对应的接口方法

public interface IMainActivity {    public void showList(List<GoosBean.DataBean> groupList, List<List<GoosBean.DataBean.DatasBean>> childList);}

这是MVP模式的Presenter层

public class MainPresenter {    private final IMainModel 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) {            }        });    }}

这是所写的网络工具类

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);    }}

这是MVP模式中的Model层

public class MainModel implements IMainModel {    private Handler handler = new Handler(Looper.getMainLooper());    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);                    }                });            }        });    }

这里是Model层对应的接口

public interface IMainModel {    public void getGoods(OnNetListener<GoosBean> onNetListener);}

获取钱和数量的方法PriceAndCountEvent

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;    }}

发送消息对错的方法MessageEvent

public class MessageEvent {    private boolean checked;    public boolean isChecked() {        return checked;    }    public void setChecked(boolean checked) {        this.checked = checked;    }}

设配器

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 groupPosition) {        return childList.get(groupPosition).size();    }    @Override    public Object getGroup(int groupPosition) {        return groupList.get(groupPosition);    }    @Override    public Object getChild(int groupPosition, int childPosition) {        return childList.get(groupPosition).get(childPosition);    }    @Override    public long getGroupId(int groupPosition) {        return groupPosition;    }    @Override    public long getChildId(int groupPosition, int childPosition) {        return childPosition;    }    @Override    public boolean hasStableIds() {        return false;    }    @Override    public View getGroupView(final int groupPosition, boolean isExpanded, View convertView, ViewGroup parent) {        View view;

       holder.cbGroup.setChecked(dataBean.isChecked());        holder.tv_number.setText(dataBean.getTitle());        //一级checkbox        holder.cbGroup.setOnClickListener(new View.OnClickListener() {            @Override            public void onClick(View v) {                dataBean.setChecked(holder.cbGroup.isChecked());                changeChildCbState(groupPosition, holder.cbGroup.isChecked());                EventBus.getDefault().post(compute());                changeAllCbState(isAllGroupCbSelected());                notifyDataSetChanged();            }        });        return view;    }    @Override    public View getChildView(final int groupPosition, final int childPosition, boolean isLastChild, View convertView, ViewGroup parent) {        View view;        final ChildViewHolder holder;        if (convertView == null) {            holder = new ChildViewHolder();            view = inflater.inflate(R.layout.item_child_market, null);            holder.cbChild = view.findViewById(R.id.cb_child);            holder.tv_tel = view.findViewById(R.id.tv_tel);            holder.tv_content = view.findViewById(R.id.tv_content);            holder.tv_time = view.findViewById(R.id.tv_time);            holder.tv_price = view.findViewById(R.id.tv_pri);
