从零到完成安卓项目实战【安卓端+后端】

今天下雨了，出不去了，在家开发一个安卓系统。

因为平时自己喜欢打篮球，那就开发一个篮球相关的系统吧：NBA安卓系统。

一，功能介绍

APP主要具备网上篮球约球、篮球交流、线上NBA观赛，力求软件界面友好、功能齐全、可拓展性良好。

系统的功能有：交流评论区模块、场馆预约模块、网上约球模块、约球留言模块、线上观赛模块、NBA球员分析模块。

通过线上篮球约球、球友交流评论、NBA比赛观看等功能，打造一款“线上观赛+线下实战”的篮球交友APP，帮助一些喜欢篮球运动的青少年可以随时随地观赛、组队、交流、交友。

二，开发语言介绍

APP基于JAVA语言进行开发，后台数据的存储采用 MySql 结合 Reids 实现数据存储，移动端通过 AndroidStudio 开发。

三，系统的界面介绍

四，核心代码演示
