本片文章主要是简单实现购物车

所以其中的数据是假数据，其中的图片和选择器都可以替换，只是简单实现一下

使用二级列表实现的 

主要的逻辑就是在适配器


首先看一下数据源GoodBean

package bwie.com.test;

import java.util.List;

public class GoodBean {

    private List<ContentBean> content;
    private int allMoney;
    private int allCount;
    private boolean isAllSelect;

    public boolean isAllSelect() {
        return isAllSelect;
    }

    public void setAllSelect(boolean allSelect) {
        isAllSelect = allSelect;
    }

    public int getAllMoney() {
        return allMoney;
    }

    public void setAllMoney(int allMoney) {
        this.allMoney = allMoney;
    }

    public int getAllCount() {
        return allCount;
    }

    public void setAllCount(int allCount) {
        this.allCount = allCount;
    }

    public List<ContentBean> getContent() {
        return content;
    }

    public void setContent(List<ContentBean> content) {
        this.content = content;
    }

    public static class ContentBean {
        private String id;
        private String address;
        private boolean isSelected;

        private List<GoodDetailBean> goodDetail;

        public String getId() {
            return id;
        }

        public void setId(String id) {
            this.id = id;
        }

        public String getAddress() {
            return address;
        }

        public void setAdress(String address) {
            this.address = address;
        }

        public boolean isSelected() {
            return isSelected;
        }

        public void setIsSelected(boolean isSelected) {
            this.isSelected = isSelected;
        }

        public List<GoodDetailBean> getGoodDetail() {
            return goodDetail;
        }

        public void setGoodDetail(List<GoodDetailBean> goodDetail) {
            this.goodDetail = goodDetail;
        }

        public static class GoodDetailBean {
            private String id;
            private String pic;
            private String count;
            private String name;
            private String price;
            private boolean isEdit;
            private boolean isSelected;

            public boolean isEdit() {
                return isEdit;
            }

            public boolean isSelected() {
                return isSelected;
            }

            public void setIsSelected(boolean isSelected) {
                this.isSelected = isSelected;
            }

            public String getId() {
                return id;
            }

            public void setId(String id) {
                this.id = id;
            }

            public String getPic() {
                return pic;
            }

            public void setPic(String pic) {
                this.pic = pic;
            }

            public String getCount() {
                return count;
            }

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


            public String getName() {
                return name;
            }

            public void setName(String name) {
                this.name = name;
            }

            public String getPrice() {
                return price;
            }

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

            public boolean isIsedit() {
                return isEdit;
            }

            public void setIsEdit(boolean isEdit) {
                this.isEdit = isEdit;
            }
        }
    }
}


会用到一个接口

package bwie.com.test;

public interface UpdataView {
    void updata(boolean isAllSelected,int count,int price);
}

MainActivity


package bwie.com.test;

import android.app.Activity;
import android.content.res.AssetManager;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.View;
import android.view.inputmethod.InputMethodManager;
import android.widget.AbsListView;
import android.widget.Button;
import android.widget.ExpandableListView;
import android.widget.TextView;

import com.google.gson.Gson;

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStream;
import java.io.InputStreamReader;


public class MainActivity extends AppCompatActivity implements UpdataView,View.OnClickListener {
    private ExpandableListView expandableListView;
    private SmoothCheckBox cbSelectAll;
    private TextView moneyAll;
    private TextView tvYunfei;
    private Button butFinish;
    StringBuffer stringBuffer;
    private GoodBean goodBean;
    ExpandableListAdapter adapter;

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

        initView();
        initData();
        initAll();

    }

    private void initAll() {
        cbSelectAll.setOnClickListener(this);
    }

    private void initData() {

        AssetManager assetManager = getAssets();
        try {
            InputStream inputStream = assetManager.open("data.json");
            BufferedReader br = new BufferedReader(new InputStreamReader(inputStream));
            stringBuffer = new StringBuffer();
            String str;
            while((str = br.readLine()) != null){
                stringBuffer.append(str);
            }
        } catch (IOException e) {
            e.printStackTrace();
        }
        Gson gson = new Gson();
        goodBean = gson.fromJson(stringBuffer.toString(),GoodBean.class);

        adapter = new ExpandableListAdapter(this,goodBean);
        adapter.setChangedListener(this);
        expandableListView.setAdapter(adapter);
        //展开所有的分组
        for (int i = 0; i < goodBean.getContent().size(); i++) {
            expandableListView.expandGroup(i);
        }
    }

    private void initView() {

        expandableListView = (ExpandableListView) findViewById(R.id.expandableListView);
        cbSelectAll = (SmoothCheckBox) findViewById(R.id.cb_select_all);
        moneyAll = (TextView) findViewById(R.id.money_all);
        tvYunfei = (TextView) findViewById(R.id.tv_yunfei);
        butFinish = (Button) findViewById(R.id.but_finish);

        //去掉二级列表默认的箭头
        expandableListView.setGroupIndicator(null);

        //用于列表滑动时，EditText清除焦点，收起软键盘
        expandableListView.setOnScrollListener(new AbsListView.OnScrollListener() {
            @Override
            public void onScrollStateChanged(AbsListView absListView, int scrollState) {
                if (SCROLL_STATE_TOUCH_SCROLL == scrollState) {
                    InputMethodManager inputMethodManager = (InputMethodManager) getSystemService(Activity
                            .INPUT_METHOD_SERVICE);
                    View focusView = getCurrentFocus();
                    if (focusView != null) {
                        inputMethodManager.hideSoftInputFromWindow(focusView.getWindowToken(), InputMethodManager
                                .HIDE_NOT_ALWAYS);
                        focusView.clearFocus();
                    }
                }
            }

            @Override
            public void onScroll(AbsListView absListView, int i, int i1, int i2) {

            }
        });


    }


    @Override
    public void updata(boolean isAllSelected, int count, int price) {
        butFinish.setText("结算：（"+count+")");
        moneyAll.setText("￥"+price);
        cbSelectAll.setChecked(isAllSelected);
    }

    @Override
    public void onClick(View v) {
        selectedAll();
    }

    private void selectedAll() {
        int allCount = goodBean.getAllCount();
        int allMoney = goodBean.getAllMoney();
        if (!cbSelectAll.isChecked()) {
            goodBean.setAllSelect(true);
            for (int i = 0; i < goodBean.getContent().size(); i++) {
                goodBean.getContent().get(i).setIsSelected(true);
                for (int n = 0; n < goodBean.getContent().get(i).getGoodDetail().size(); n++) {
                    if (!goodBean.getContent().get(i).getGoodDetail().get(n).isSelected()) {
                        allCount++;
                        allMoney += Integer.valueOf(goodBean.getContent().get(i).getGoodDetail().get(n).getCount())
                                * Integer.valueOf(goodBean.getContent().get(i).getGoodDetail().get(n).getPrice());
                        goodBean.getContent().get(i).getGoodDetail().get(n).setIsSelected(true);
                    }
                }
            }
        } else {
            goodBean.setAllSelect(false);
            for (int i = 0; i < goodBean.getContent().size(); i++) {
                goodBean.getContent().get(i).setIsSelected(false);
                for (int n = 0; n < goodBean.getContent().get(i).getGoodDetail().size(); n++) {
                    goodBean.getContent().get(i).getGoodDetail().get(n).setIsSelected(false);
                }
                allCount = 0;
                allMoney = 0;
            }
        }
        goodBean.setAllMoney(allMoney);
        goodBean.setAllCount(allCount);
        updata(goodBean.isAllSelect(), allCount, allMoney);
        adapter.notifyDataSetChanged();
    }
}


最后是二级列表的适配器

主要的操作是在这里面
