Android ProvinceDistrict菜单，android 省市区县三级联动菜单，在弹出的选择框中，支持内容列表滚动。盛市、县菜单内容事前存储在文件中，结合JSON当用户选择时，从assert文件夹中读取省市区的json文件，然后转化为json对象，加载对应的区县内容，完成后释放Json对象的内存，实现的步骤： 　　把全国的省市区的信息以json的格式保存，解析完成后赋值为null 　　设置，省，市，县，的适配器，进行动态设置其中的值 begin 　　设置控件点击选择监听 　　根据当前的省，更新市和地区信息，第三个地址是详细地址，并且是第一次设置edtext值，正好，地址的长度为3的时候，设置详细地址。 　　不懂的地方，可参见本源码中的注释，非常丰富。

这是单片机与蓝牙的进行的通信的一个程序。首先，单片机端的是C语言程序。基本上常见的单片机平台都可以使用。 手机端的程序是基于Java的Android程序。对于学习这方面的朋友，这个程序可以起到非常好的作用。

本代码适合那些刚入门学习android的人，这个简单的APP带有比较简单的界面，并且注释比较详细，适合刚学习android界面组件的人
