摘　　要：指南针应用在很多手机上都有安装,但是各个厂家所使用的的实现方式却不尽相同,指南针应用以指示方向为基本功能,本文在此基础上进行了扩展,实现了指示方向、水平仪、垂直仪等功能,技术上采用了方向传感器和加速度传感器进行设计,创新性的在指示方向时采用通过数学计算进行文字绘制的方式,保证了指示方向时文字始终朝向屏幕上方的显示形式,垂直水平仪的实现采用根据加速度传感器投射角度计算绘制圆形或直线的形式,其显示效果令人满意。Compass applications are installed on many mobile phones,but the implementation methods used by different manufacturers are not the same.The compass application takes the direction indication as the basic function.Based on this,this paper expands it to realize the functions of indicating direction,level and verticality.In technology,it uses direction sensor and acceleration sensor to design,innovatively in the indicator side The vertical level instrument adopts the form of drawing circle or straight line according to the projection angle of acceleration sensor,and the display effect is satisfactory.
