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. (2020-03-28, Java, 15783KB, 下载4次)
① activty(程序UI)：
负责用户界面的显示，即玩家进入打开游戏程序之后看到的画面及操作按键和显示信息等，是游戏的前端。

该部分是展示游戏基本内容的区域，游戏图片，任务等内容会在这里显示，提供基本的游戏功能和接口。
③ 游戏控制器（控制游戏逻辑）
对于游戏内容逻辑的控制实现，根据用户动作来更新游戏布局内容，控制消除/生成/死亡等等逻辑功能，是游戏核心部分。

For the control implementation of the game content logic, the core part of the game is to update the game layout content according to the user's actions and control the logic functions such as elimination / generation / death. (2020-02-26, Java, 5460KB, 下载1次)
动作类游戏是最传统的游戏类型之一，主要是由玩家所控制的人物或角色根据周围环境的变化，利用键盘或者手柄、鼠标的按键做出一定的动作，如移动、跳跃、攻击、躲避、防守等，来达到游戏要求的相应目标，一般是为了过关。现在的动作类游戏则融入了很多新的元素，很多经典的关卡以及很多画面的特效，使其逐渐成为所有游戏类型里面款式最多，发展最快的一种。
3D空战便是动作类游戏的一种，其中融入了很多动作类游戏特有的技术，且画面流畅、声音震撼。
android系统下的实现
The action game is one of the most traditional type of game, mainly controlled by the player character or role changes in the surrounding environment, using the keyboard or joystick, a mouse button to make a certain action, such as move, jump, attack, evade , defense, etc., to achieve the appropriate goal of the game requires, usually in order to pass. Now the action game into a lot of new elements, many classic levels and many picture effects, it is becoming all the game types which style most of the fastest growing. 3D Air Combat is a action game, incorporating a lot of action games unique technology, the screen smooth voice shook. android system implementation (2012-07-08, Java, 3207KB, 下载33次)
