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:HttpUtilspublic 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basexEpandableListAdapterpublic class MyAdapter extends BaseExpandableListAdapter{ private Context context; private List<GoosBean.DataBean> groupList; private List<List<GoosBean.DataBean.DatasBean>> childList;
