说明：  不仅仅是一个简单的计步器源码，还是个手机传感器数据采集工具，加速度、重力和陀螺仪数据被保存到sqlite数据库中，存储在手机的Download目录下，以便后续取出来进行数据处理。压缩包包含Android源码（Android Studio3.5开发），matlab读取sqltie数据库插件和处理数据的示例程序，以及一个说明文档。这个程序是写来给学生上数字处理课程设计用的。 绝对原创。还是挺好玩的。
(It is not only a simple pedometer source code, but also a mobile sensor data acquisition tool. Acceleration, gravity and gyroscope data are saved in SQLite database and stored in the download directory of the mobile phone for subsequent data processing. The compressed package includes Android source code (developed by Android studio 3.5), sample program of reading sqltie database plug-in and processing data by MATLAB, and a description document. This program is written for students to design digital processing courses. Absolutely original. It's still fun.)
