基于语音控制的智能衣柜系统——安卓手机APP的实现
作者：互联网
1.这是安卓APP实现的主活动------MainActivity.java
读这篇文章前，最好先阅读这篇索引文章
如果一点安卓基础都没有的，麻烦请先入门，另外学一学Android Studio的基础知识。
APP使用的是socket框架，通过tcp/ip协议与单片机通信。
由于我写这个代码的时候是大四第一学期刚开学临时学的，所以写的不是很好，代码也没有优化，包括UI也不美观，仅仅是实现了应有的功能而已。
对于没有加注释很抱歉，但是代码很短，基本上学过Java和安卓基础的都能看懂的，相信我。
如果你是一个安卓小白，并且已经安卓好Android Studio了，学会如何创建一个empty Activity了的话，那就创建好空的Activity之后，把对应的MainActivity.java和activity_main.xml代码替换成我给出来的代码就好啦！

2.这个是xml，温湿度和气体浓度初始值默认为0；当接收到单片机的发送过来的数据后，对应的数值会更新！

3.如果你很熟悉Android Studio的话，也可以直接使用我的全部源码！
4.关于APP的一些应该要优化的地方：
（1）逻辑：因为之前刚入门，所以可能在一些语句的逻辑上会有问题。但是不影响功能实现。
（2）当APP接收到单片机传过来的数据时，点击按钮会不灵敏，也就是说，点击按钮没有用，这是因为WiFi模块的接收函数已经被单片机那边占用了，不能同时再接收来自APP的数据，这个问题也困扰了我很久，我最后是在单片机那里把发送数据给APP的频率降低一点，改成每10秒发一次，就优化了这个问题，但是我现在还没有别的更好的办法去解决这个问题的根源，我也问过了老师，他也不知道…那就留给你们帮我想把，哈哈哈…
（3）界面太简陋，因为只有一个界面，所有功能都集成在一个界面了…
（4）暂时还没有增加用户和服务器数据库的功能，这些在后面的章节我会说。
