首先，我们得有个实体类
public class PhonesInfo {
public String flag;
public String code;
public List<DataInfo> data;
public String getFlag() {
return flag;
}
public void setFlag(String flag) {
this.flag = flag;
}
public String getCode() {
return code;
}
public void setCode(String code) {
this.code = code;
}
public List<DataInfo> getData() {
return data;
}
public void setData(List<DataInfo> data) {
this.data = data;
}
public static class DataInfo {
public String title;
public List<DatasInfo> datas;
public boolean allCheck = false;
public String getTitle() {
return title;
}
public void setTitle(String title) {
this.title = title;
}
public List<DatasInfo> getDatas() {
return datas;
}
public void setDatas(List<DatasInfo> datas) {
this.datas = datas;
}
public boolean isAllCheck() {
return allCheck;
}
public void setAllCheck(boolean allCheck) {
this.allCheck = allCheck;
}
public static class DatasInfo {
public int price;
public String type_name;
public List<String> msg;
public String add_time;
public boolean itemCheck = false;
public int getPrice() {
return price;
}
public void setPrice(int price) {
this.price = price;
}
public String getType_name() {
return type_name;
}
public void setType_name(String type_name) {
this.type_name = type_name;
}
public List<String> getMsg() {
return msg;
}
public void setMsg(List<String> msg) {
this.msg = msg;
}
public String getAdd_time() {
return add_time;
}
public void setAdd_time(String add_time) {
this.add_time = add_time;
}
public boolean isItemCheck() {
return itemCheck;
}
public void setItemCheck(boolean itemCheck) {
this.itemCheck = itemCheck;
}
}
}
}
接下来，我们的用网络请求数据，这里我们封装了个工具类
public class MyOkHttp {
public static OkHttpClient client=new OkHttpClient();
public static String get(String url,String key,String value){
FormEncodingBuilder builder=new FormEncodingBuilder();
builder.add(key,value);
Request request = new Request.Builder().url(url).post(builder.build()).build();
try {
Response response = client.newCall(request).execute();
if (response.isSuccessful()){
return response.body().string();
}
} catch (IOException e) {
e.printStackTrace();
}
return null;
}
}
接下来就是我们的主界面了，不多说，直接上代码
public class MainActivity extends AppCompatActivity {
private ExpandableListView elv;
private CheckBox cb;
private TextView tv_count;
private TextView tv_sum;
private PhonesInfo phonesInfo;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
//找控件
initView();
//获取网络数据
getServerData();
}
/**
* 获取网络数据
*/
private void getServerData() {
String url = “http://api.ehu
