Android（安卓）订餐APP(Sqlite数据库，完整的增删改查)

一.背景

首先说说项目的背景，基于地铁口鸡蛋饼的一个小项目，APP中固定设置的鸡蛋饼搭配，顾客也可以自己搭配

二.开发环境

AndroidStudio3.0.1
JDK1.8
语言：JAVA
数据存储：Sqlite

三.功能

注册、登录、管理员、普通用户
首页:鸡蛋饼食材搭配
订单:购买订单展示
个人/管理:个人信息、用户信息、机器信息、订单管理、食材管理、退出登录等
技术知识:Sqlite增删改查、glide图片加载、Spinner、EventBus、butterknife等等

四.功能图

五.Sqlite数据库存储(增删改查)

字段值	数据类型	说明
id	text	主键值
nickName	text	用户名
password	text	密码
path	text	头像
qianming	text	签名
phone	text	手机号
birthday	text	生日
sex	text	性别
type	text	用户类型

用户表

代码如下:
