(安卓) 购物车二级列表，计算和全反选 以及 EventBus（消息传递）

先看效果图：

MainActivity;

import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;
import android.view.View;
import android.widget.CheckBox;
import android.widget.ExpandableListView;
import android.widget.TextView;

import bwie.com.day_shoping_21.bean.GoodsBean;
import bwie.com.day_shoping_21.prasenter.Presaenter;
import bwie.com.day_shoping_21.view.IView;

public class MainActivity extends AppCompatActivity implements IView{
private ExpandableListView elv;
private  List<List<GoodsBean.DataBean.DatasBean>> data=new ArrayList<List<GoodsBean.DataBean.DatasBean>>();
private CheckBox mQuanxuan;
private TextView zongjia;
private TextView heji;
private MyAdapter myAdapter;

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

elv = (ExpandableListView) findViewById(R.id.elv);
mQuanxuan = (CheckBox) findViewById(R.id.quanxuan);
zongjia = (TextView) findViewById(R.id.zongji);
heji = (TextView) findViewById(R.id.heji);

Presaenter presaenter = new Presaenter();
presaenter.attachView(this);
presaenter.getNews();
//注册EventBus
EventBus.getDefault().register(this);
mQuanxuan.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
//判断全选的状态
myAdapter.checkALLStatus(mQuanxuan.isChecked());
}
});
}

@Override
public void success(List<GoodsBean.DataBean> news) {
//遍历一级列表
for (int i = 0; i <news.size() ; i++) {
GoodsBean.DataBean dataBean = news.get(i);
//得到二级的对象
List<GoodsBean.DataBean.DatasBean> datas = dataBean.getDatas();
//将其添加到二级列表中
data.add(datas);
}
//适配器
myAdapter = new MyAdapter(this, news, data);
//设置适配器
elv.setAdapter(myAdapter);
//将一级列表的展开标志隐藏
elv.setGroupIndicator(null);
//循环集合
for (int i = 0; i <news.size() ; i++) {
//将二级列表展开
elv.expandGroup(i);
}

}

@Override
public void failed(Exception e) {

}

//接收适配器传过来的值
@Subscribe
public void onMessageEvent(MessageEvent event) {
//接收适配器（Myadpader）传递过来的值 ，将全选的状态设置为true或者false
mQuanxuan.setChecked(event.isCheck());
}
//接收适配器传过来的数量和总价
@Subscribe
public void onMessageEvent(CountPrice event) {
zongjia.setText("结算（"+event.getCount()+")"+"");
heji.setText("总计："+event.getPrice()+"");
}
@Override
protected void onDestroy() {
super.onDestroy();
EventBus.getDefault().unregister(this);
}
}

适配器所用到的类：

public class CountPrice {
private int count;
private int price;

public int getCount() {
return count;
}

public void setCount(int count) {
this.count = count;
}

public int getPrice() {
return price;
}

public void setPrice(int price) {
this.price = price;
}
}

public class MessageEvent {
private boolean check;

public boolean isCheck() {
return check;
}

public void setCheck(boolean check) {
this.check = check;
}
}

适配器：（主要判断都在这里）

模型层接口：

视图层接口：

P层

public class Presaenter {

//定义一个方法让iv等于空      防止内存泄漏问题

接下来就是布局了：

增加的一点小业务逻辑 自己套用把 点击编辑显示和隐藏控件：主要逻辑：private int isxian=View.VISIBLE;

 //在一级列表里面点击时viewHodler1.bianji.setOnClickListener(new View.OnClickListener() {@Overridepublic void onClick(View view) {if(isxian==View.VISIBLE) {isxian=View.GONE;}else{isxian=View.VISIBLE;}notifyDataSetChanged();}});

 //在二级列表找到需要隐藏的控件给赋值viewHodler2.del.setVisibility(isxian);
