Android选择颜色，尺码联动

来源：互联网发布：晨曦软件视频编辑：程序博客网时间：2024/04/29 02:43

最近项目遇到一个功能，类似淘宝的购物颜色，尺码联动。
说重点吧，感受比较深的是数据驱动吧，类似前端的Vue.js。
先看一下适配器数据模型吧

public class DemoModel implements Serializable{    private String id;    private String content;    private boolean isSelect;//是否选中    private List<String> mlist;//对应关联    private boolean isEnableClick;//是否可点    public List<String> getMlist() {        return mlist;    }    public void setMlist(List<String> mlist) {        this.mlist = mlist;    }    public boolean isSelect() {        return isSelect;    }    public void setSelect(boolean select) {        isSelect = select;    }    public boolean isEnableClick() {        return isEnableClick;    }    public void setEnableClick(boolean enableClick) {        isEnableClick = enableClick;    }    public DemoModel(String id, String content,boolean isSelect,boolean isEnableClick,List<String> mlist) {        super();        this.id = id;        this.content = content;        this.isEnableClick =isEnableClick;        this.isSelect =isSelect;        this.mlist = mlist;    }    public String getId() {        return id;    }    public void setId(String id) {        this.id = id;    }    public String getContent() {        return content;    }    public void setContent(String content) {        this.content = content;    }}

通过修改状态值来刷新适配器notifyDataSetChanged();
适配器类

其中fillview其实类似getView方法，写在getview方法里即可。代码太多就不一一贴了。
