Android 双RecyclerView嵌套实现购物车逻辑

下面代码通过Recyclerview嵌套Recyclerview实现了购物车的全选、反选和点选。先来看看效果图吧！
先来看看效果图吧，看看是不是你想要的：
左边是空的购物车页面，右边是添加入数据的购物车；

首先来主页面xml布局：

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayoutxmlns:android="http://schemas.android.com/apk/res/android"android:orientation="vertical" android:layout_width="match_parent"android:layout_height="match_parent"><RelativeLayoutandroid:layout_width="match_parent"android:layout_height="58dp"android:id="@+id/toolbar_tou"android:background="#fff"android:layout_alignParentTop="true"android:layout_alignParentStart="true"><TextViewandroid:layout_width="wrap_content"android:layout_height="wrap_content"android:text="购物车"android:id="@+id/toolbar_text"android:textSize="18sp"android:textColor="#1b1919"android:layout_centerInParent="true"/><TextViewandroid:visibility="gone"android:layout_width="wrap_content"android:layout_height="wrap_content"android:id="@+id/bianji"android:text="编辑"android:textSize="16sp"android:textColor="#1b1919"android:layout_centerVertical="true"android:layout_marginEnd="6dp"android:layout_toLeftOf="@+id/xiaoxi"/><ImageViewandroid:layout_width="wrap_content"android:layout_height="wrap_content"android:id="@+id/xiaoxi"android:background="@drawable/manages"android:layout_centerVertical="true"android:layout_alignParentRight="true"android:layout_marginRight="8dp"/></RelativeLayout><TextViewandroid:layout_width="match_parent"android:layout_height="1dp"android:id="@+id/toolbar_xian"android:background="#ddd"android:layout_below="@+id/toolbar_tou"/><com.jwenfeng.library.pulltorefresh.PullToRefreshLayoutandroid:layout_width="match_parent"android:layout_height="match_parent"android:id="@+id/pull_cars"android:layout_below="@id/toolbar_xian"><ScrollViewandroid:layout_width="match_parent"android:layout_height="match_parent"android:layout_below="@+id/toolbar_xian"><RelativeLayoutandroid:layout_width="match_parent"android:layout_height="match_parent"android:background="#fff"><RelativeLayoutandroid:layout_width="match_parent"android:layout_height="34dp"android:id="@+id/login_zt"android:background="#fff"><Buttonandroid:layout_width="75dp"android:layout_height="23dp"android:text="登录"android:id="@+id/login_cars_btn"android:layout_centerVertical="true"android:background="@drawable/cars_btn_two3"android:layout_marginLeft="20dp"/><TextViewandroid:layout_width="wrap_content"android:layout_height="wrap_content"android:id="@+id/login_text"android:text="登录后同步电脑与手机购物车中的商品"android:textSize="16sp"android:layout_centerVertical="true"android:layout_toRightOf="@id/login_cars_btn"android:textColor="#a1a0a0"android:layout_marginLeft="10dp"/></RelativeLayout><TextViewandroid:layout_width="match_parent"android:layout_height="1dp"android:id="@+id/xian4"android:background="#ddd"android:layout_below="@id/login_zt"/><RelativeLayoutandroid:layout_width="match_parent"android:layout_height="110dp"android:layout_below="@+id/xian4"android:id="@+id/cars_login"android:background="#fff"><ImageViewandroid:layout_width="50dp"android:layout_height="38dp"android:id="@+id/cars_icons"android:background="@mipmap/cars_icons"android:layout_alignParentTop="true"android:layout_alignParentStart="true"android:layout_marginStart="103dp"android:layout_marginTop="10dp"

</RelativeLayout>

主界面布局中Button的背景属性设置：

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"><cornersandroid:radius="20dp"></corners><solidandroid:color="#f00"></solid>
</shape>

其中还有一个MyRecy是一个自定义的RecyclerView控件，下面是自定义的代码：

package com.example.zhangtao.jing_east;
import android.content.Context;
import android.support.annotation.Nullable;
import android.support.v7.widget.RecyclerView;
import android.util.AttributeSet;public class My_Recy extends RecyclerView{public My_Recy(Context context) {this(context,null);}public My_Recy(Context context, @Nullable AttributeSet attrs) {this(context, attrs,0);}public My_Recy(Context context, @Nullable AttributeSet attrs, int defStyle) {super(context, attrs, defStyle);}@Overrideprotected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {int expanSpec = MeasureSpec.makeMeasureSpec(Integer.MAX_VALUE >> 2, MeasureSpec.AT_MOST);super.onMeasure(widthMeasureSpec,expanSpec);}
}

接下来是商铺的xml布局图：

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"android:orientation="vertical"android:layout_width="match_parent"android:layout_height="match_parent"android:background="#fff"><RelativeLayoutandroid:layout_width="match_parent"android:layout_height="35dp"android:id="@+id/item_father"><CheckBoxandroid:layout_width="wrap_content"android:layout_height="wrap_content"android:id="@+id/item_father_check"android:layout_marginLeft="5dp"/><ImageViewandroid:layout_width="22dp"android:layout_height="22dp"android:background="@drawable/shop_icon"android:layout_centerVertical="true"android:layout_marginLeft="10dp"android:id="@+id/shop_icon"android:layout_toRightOf="@+id/item_father_check"/><TextViewandroid:layout_width="wrap_content"android:layout_height="wrap_content"android:id="@+id/item_father_shopname"android:text="商品1"android:layout_toRightOf="@+id/shop_icon"android:textSize="18sp"android:textColor="#313030"android:layout_centerVertical="true"android:layout_marginLeft="7dp"/></RelativeLayout><TextViewandroid:layout_width="match_parent"android:layout_height="1dp"android:id="@+id/item_father_xian"android:background="#ddd"android:layout_below="@+id/item_father"/><android.support.v7.widget.RecyclerViewandroid:layout_width="match_parent"android:layout_height="wrap_content"android:layout_below="@+id/item_father_xian"android:id="@+id/recy_chiled"></android.support.v7.widget.RecyclerView>
</RelativeLayout>

紧接着就是商铺的xml布局了：

<?xml version="1.0" encoding="utf-8"?>

这个页面中有许多数据都是在两个适配器里通过接口回调调出来的，所以接下来就是适配器的代码：
首先是商铺的适配器，商品的适配器建立在了商铺适配器中：

package MyAdapter;
import android.content.Context;
import android.support.v7.widget.LinearLayoutManager;
import android.support.v7.widget.RecyclerView;
import android.view.View;
import android.view.ViewGroup;
import android.widget.CheckBox;
import android.widget.CompoundButton;
import android.widget.TextView;
import com.example.zhangtao.jing_east.R;
import java.util.List;
import Bean.CarsBean.DataBean;public class Recy_Father extends RecyclerView.Adapter<Recy_Father.ViewHolder>{private Context conn;private List<DataBean> data;private Recy_Chileds recy_chileds_adapter;public Recy_Father(Context context, List<DataBean> data) {this.conn = context;this.data = data;}@Overridepublic Recy_Father.ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {View inflate = View.inflate(conn, R.layout.shop_item, null);ViewHolder viewHolder = new ViewHolder(inflate);return viewHolder;}@Overridepublic void onBindViewHolder(final ViewHolder holder, final int position) {holder.shop_title.setText(data.get(position).getSellerName());LinearLayoutManager manager = new LinearLayoutManager(conn);manager.setOrientation(LinearLayoutManager.VERTICAL);holder.recy_chileds.setLayoutManager(manager);recy_chileds_adapter = new Recy_Chileds(conn,data.get(position).getList());holder.recy_chileds.setAdapter(recy_chileds_adapter);//先设置一次CheckBox的选中监听器，传入参数nullholder.shop_che.setOnCheckedChangeListener(null);//用数组中的值设置CheckBox的选中状态holder.shop_che.setChecked(data.get(position).ischeck());holder.shop_che.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {@Overridepublic void onCheckedChanged(CompoundButton compoundButton, final boolean b) {if(mCallBack != null) {mCallBack.OnCheckLinstener_Father(b,position);}recy_chileds_adapter.setOnDelete(new Recy_Chileds.ondelelte() {@Overridepublic void onDelete(int chiled_pos,boolean chiled_flag) {if(mondele != null) {mondele.OnDelete(chiled_pos,chiled_flag,position,b);}}});}});recy_chileds_adapter.setCallBack(new Recy_Chileds.allCheck() {@Overridepublic void OnCheckLinstener_Chiled(boolean isChecked, final int chiledposition) {if(mCallBack != null) {mCallBack.OnItemCheckLinstener(isChecked,position,chiledposition);}}});recy_chileds_adapter.setAddjian(new Recy_Chileds.jiajian() {@Overridepublic void Onadd(int addcount) {if(mCallBack != null) {mCallBack.Onadd(addcount);}}@Overridepublic void Onjian(int jiancount) {if(mCallBack != null) {mCallBack.Onjian(jiancount);}}});}@Overridepublic int getItemCount() {if(data == null) {return  0;}return data.size();}class ViewHolder extends RecyclerView.ViewHolder {private CheckBox shop_che;private TextView shop_title;private RecyclerView recy_chileds;public ViewHolder(View itemView) {super(itemView);shop_che = itemView.findViewById(R.id.item_father_check);shop_title = itemView.findViewById(R.id.item_father_shopname);recy_chileds = itemView.findViewById(R.id.recy_chiled);}}private allCheck mCallBack;public void setCallBack(allCheck CallBack) {this.mCallBack = CallBack;}public interface allCheck {void OnCheckLinstener_Father(boolean flag,int position);void OnItemCheckLinstener(boolean isSelected,int fatherposition,int chiledsposition);void Onadd(int addnNum);void Onjian(int jiannNum);}//deleteprivate ondele mondele;public void setOnDeleLinstener(ondele ondele) {this.mondele = ondele;}public interface ondele{void OnDelete(int chiled_pos,boolean chiled_flag,int father_pos,boolean father_flag);}
}

接下来是商品的适配器了：

//    deleteprivate ondelelte mdel;public void setOnDelete(ondelelte ondel) {this.mdel = ondel;}public interface ondelelte {void onDelete(int chiledpos,boolean chiled_flag);}
}

这里面使用的数据是网络请求的数据，所以大家在使用的自己请求数据。
