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：

         android:layout_width="90dp"            android:layout_height="35dp"            android:text="去结算"            android:id="@+id/price_btn"            android:layout_alignParentRight="true"

android:visibility="invisible"            android:layout_width="80dp"            android:layout_height="35dp"            android:text="分享"            android:id="@+id/fen_btn"            android:background="@drawable/shopcar_btn1"            android:layout_toRightOf="@id/quan_che"            android:layout_centerVertical="true"            android:layout_marginLeft="18dp"            />        <Button            android:visibility="invisible"            android:layout_width="80dp"            android:layout_height="35dp"            android:text="收藏"            android:id="@+id/shou_btn"            android:background="@drawable/shopcar_btn2"            android:layout_toRightOf="@id/fen_btn"            android:layout_centerVertical="true"            android:layout_marginLeft="18dp"            />        <Button            android:visibility="invisible"            android:layout_width="80dp"            android:layout_height="35dp"

android:layout_centerVertical="true"            android:layout_marginLeft="18dp"            />    </RelativeLayout></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"    >    <corners        android:radius="20dp"        ></corners>    <solid        android: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);    }    @Override    protected 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"    >  <RelativeLayout      android:layout_width="match_parent"      android:layout_height="35dp"      android:id="@+id/item_father"      >      <CheckBox          android:layout_width="wrap_content"          android:layout_height="wrap_content"          android:id="@+id/item_father_check"          android:layout_marginLeft="5dp"          />      <ImageView          android: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"          />      <TextView          android: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>    <TextView        android: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.RecyclerView        android: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：
