本文实例为大家分享了rxjava retrofit实现购物车展示的具体代码,供大家参考,具体内容如下 。

先给大家展示一下效果图 。

RxJava+Retrofit+Mvp实现购物车

框架结构:

1.项目框架:mvp,图片加载用fresco,网络请求用okhttp+retrofit实现(自己封装,加单例模式), 2.完成购物车数据添加(如果接口无数据,可用接口工具添加数据), 3.自定义view实现加减按钮,每次点击加减,item中的总数及总价要做出相应的改变。 4.当数量为1时,点击减号,数量不变,吐司提示用户最小数量为1。 5.底部总数及总价为所有item项中的总价及总数,每个item中数量价格的更改,底部总价总数要与之联动 6.实现单选反选全选功能,首次进入默认全选,item未选中时总数及总价不计入底部数据,改变选中状态时,底部总数及总价能做出正确修改 7.点击删除按钮,删除item,底部总数及总价能做出正确修改,接口数据删除.

添加所需要的依赖和联网权限 。
