学习笔记 Tianmao 篇 recyclerView 辅助的RecycleAdapterImpl类（适配自定义home三型）

一 .这里是承接学习笔记 Tianmao 篇 RecyclerView.Adapter 的封装

二.这里只贴RecycleAdapterImpl类代码对应的javabean 和 布局 以及 相应的效果

三.规格为 效果图—Impl类 —javabean —布局—-style

1.效果图

2.Impl类

3.javabean

1.外层

package pers.lijunxue.tianmao.javabean;/**真正的recyclor中的javabean * Created by rabook on 2016/10/25. */public class HomeThirdViewBean extends ViewBean {    public static final int TYPE = 3;    private int id;    private String title;    private HomeThirdViewItemBean cpOne;    private HomeThirdViewItemBean cpTwo;    private HomeThirdViewItemBean cpThree;    //jason在解析时候构造的是无参构造函数  所以这里要注意    public HomeThirdViewBean()    {        super(TYPE);    }    public HomeThirdViewBean(int id, String title,  HomeThirdViewItemBean cpOne,                                                    HomeThirdViewItemBean cpTwo,                                                    HomeThirdViewItemBean cpThree) {        super(TYPE);        this.id = id;        this.title = title;        this.cpOne = cpOne;        this.cpTwo = cpTwo;        this.cpThree = cpThree;    }    public int getId() {        return id;    }    public void setId(int id) {        this.id = id;    }    public String getTitle() {        return title;    }    public void setTitle(String title) {        this.title = title;    }    public HomeThirdViewItemBean getCpOne() {        return cpOne;    }    public void setCpOne(HomeThirdViewItemBean cpOne) {        this.cpOne = cpOne;    }    public HomeThirdViewItemBean getCpTwo() {        return cpTwo;    }    public void setCpTwo(HomeThirdViewItemBean cpTwo) {        this.cpTwo = cpTwo;    }    public HomeThirdViewItemBean getCpThree() {        return cpThree;    }    public void setCpThree(HomeThirdViewItemBean cpThree) {        this.cpThree = cpThree;    }}

2.内层

package pers.lijunxue.tianmao.javabean;/**用于获取网络数据，HomeThirdView中的数据,子bean * Created by rabook on 2016/10/25. */public class HomeThirdViewItemBean {    private int id;    private String title;    private String imgUrl;    public HomeThirdViewItemBean(int id, String title, String imgUrl) {        this.id = id;        this.title = title;        this.imgUrl = imgUrl;    }    public HomeThirdViewItemBean() {    }    public int getId() {        return id;    }    public void setId(int id) {        this.id = id;    }    public String getTitle() {        return title;    }    public void setTitle(String title) {        this.title = title;    }    public String getImgUrl() {        return imgUrl;    }    public void setImgUrl(String imgUrl) {        this.imgUrl = imgUrl;    }}
