一导依赖mycartutils（购物车） okhttputils（网络请求）

二将mycartutils下的版本改为minSdkVersion 15

主布局

<LinearLayout    xmlns:android="http://schemas.android.com/apk/res/android"    xmlns:app="http://schemas.android.com/apk/res-auto"    android:orientation="vertical"    xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent"    android:layout_height="match_parent" tools:context="com.bwei.shoppingdemozong.MainActivity">    <ExpandableListView        android:layout_width="match_parent"        android:layout_height="wrap_content"        android:id="@+id/ex"        android:layout_weight="1"        ></ExpandableListView>    <LinearLayout        android:layout_width="match_parent"        android:layout_height="50dp"        android:layout_alignParentBottom="true"        android:orientation="horizontal">        <CheckBox            android:id="@+id/all"            android:layout_width="50dp"            android:layout_height="50dp" />        <TextView            android:id="@+id/count"            android:layout_width="0dp"            android:layout_height="match_parent"            android:layout_weight="1"            android:gravity="center"            android:text="数量" />        <TextView            android:id="@+id/name"            android:layout_width="0dp"            android:layout_height="match_parent"            android:layout_weight="1"            android:gravity="center"            android:text="价钱" />    </LinearLayout></LinearLayout>

主类

public class MainActivity extends AppCompatActivity {    private ExpandableListView ex;    private TextView price;    private TextView count;    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_main);        ex = (ExpandableListView) findViewById(R.id.ex);        final CheckBox all = (CheckBox) findViewById(R.id.all);        count = (TextView) findViewById(R.id.count);        price = (TextView) findViewById(R.id.name);        HttpUtils.doGet("http://www.yulin520.com/a2a/impressApi/news/mergeList?sign=C7548DE604BCB8A17592EFB9006F9265&pageSize=20&gender=2&ts=1871746850&page=1 ", new HttpUtils.GsonObjectCallback<JavaBean>() {            @Override            public void onUi(JavaBean javaBean) {                List<JavaBean.DataBean> data = javaBean.getData();                List<GroupBean> groupBeen = new ArrayList<GroupBean>();                List<List<ChildBean>> child = new ArrayList<List<ChildBean>>();                for (int i = 0; i < data.size(); i++) {                    groupBeen.add(new GroupBean(data.get(i).getTitle(), false));                }                for (int i = 0; i < data.size(); i++) {                    List<ChildBean> ch = new ArrayList<ChildBean>();                    for (int j = 0; j < data.size(); j++) {                        ch.add(new ChildBean(data.get(j).getTitle(), "100", data.get(j).getImg(), false, 1));                    }                    child.add(ch);                }
                //依赖中的方法                CartUtils.setCartData(MainActivity.this, groupBeen, child, ex, all, price, count);            }            @Override            public void onFailed(Call call, IOException e) {            }        });    }}
