 eventbusevent包里面创建二两个类，一个是MessageEvent、PriceAndCountEvent

public class MessageEvent {
private boolean checked;

public boolean isChecked() {
return checked;
}

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

 

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;
}

}

 

model包创建二两个类，一个是IMainModel接口，MainModel

public interface IMainModel {

public void getGoods(OnNetListener<GoosBean> onNetListener);

}

 

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() {

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);
}
});
}
});
}
}

 
net包里面创建三个类，第一个类 Api 接口是 获取网络数据的，第二类 HttpUtils 是请求，第三个类OnNetListener接口。

public interface Api {
//网上获取数据
public static final String url = "http://result.eolinker.com/iYXEPGn4e9c6dafce6e5cdd23287d2bb136ee7e9194d3e9?uri=evaluation";

}

 

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) {

httpUtils = new HttpUtils();
}
}
}
return httpUtils;
}

/**

*
* @param url
* @param callback
*/
public void doGet(String url, Callback callback) {
Request request = new Request.Builder().url(url).build();
client.newCall(request).enqueue(callback);
}
}

 

public interface OnNetListener<T> {

public void onSuccess(T t);

public void onFailure(Exception e);

}

Presenter包里面创建一个MainPresenter类

public class MainPresenter {

private final IMainModel imainModel;
private final IMainActivity iMainActivity;

public MainPresenter(MainActivity 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) {

}
});

}
}

 View包里面创建二个类，第一个是IMainActivity接口，第二个就是MainActivity主页面

public interface IMainActivity {

//view接口进行调用
public void showList
(List<GoosBean.DataBean>
groupList, List<List<GoosBean.DataBean.DatasBean>>childList);

}

 

//主页面，调用IMainActivity的接口
public class MainActivity extends AppCompatActivity
implements IMainActivity {

private ExpandableListView mElv;
private CheckBox mCheckbox2;
/**
* 0
*/
private TextView mTvPrice;
/**
* 结算(0)
*/
private TextView mTvNum;
private MyAdapter adapter;

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);

EventBus.getDefault().register(this);

//方法
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);
}

}

@Subscribe
public void onMessageEvent(MessageEvent event) {

mCheckbox2.setChecked(event.isChecked());

}

@Subscribe
public void onMessageEvent(PriceAndCountEvent event) {

mTvNum.setText("结算(" + event.getCount() + ")");
mTvPrice.setText(event.getPrice() + "");
}

}
