大部分Android平台的设备都带有多个传感器,使你能监视其方位和运动状态的变化.很多设备还有其它类型的传感器,让你能感知周围的环境条件,比如温度.压力.湿度和光线.你可以利用Android的传感器框架访问这些传感器,并获取原始的传感器数据. 传感器框架提供了丰富的类和接口,能帮助你完成很多与传感器有关的工作.比如,你可以用传感器框架来进行: 确定设备上可用的传感器 确定某个传感器的性能,比如量程.制造商.能耗.分辨率等. 读取传感器的原始数据并指定最小读取频率 注册及注销监听传感器变化的传感器

定位(Location) 和 传感器(Sensors)API充分发挥了移动设备的优势,您可以调用这些API,制作出交互性较高的应用程序,比如使用设备自带的GPS模块定位.或使用网络定位:使用加速器模块(accelerometer)监听设备的加速度.陀螺仪模块(gyroscope)监听设备偏转/倾斜时的转动角速度.温度计模块(temperature)测量当前设备所处环境的温度.气压计模块(barometer)测量当前设备所处环境的气压 等. 本文将介绍Android中地理定位的技术要点.在下一篇文

HDU 4869 Turn the pokers 题目链接 题意:给定n个翻转扑克方式,每次方式相应能够选择当中xi张进行翻转.一共同拥有m张牌.问最后翻转之后的情况数 思路:对于每一些翻转,假设能确定终于正面向上张数的情况,那么全部的情况就是全部情况的C(m, 张数)之和.那么这个张数进行推理会发现,事实上会有一个上下界,每隔2个位置的数字就是能够的方案,由于在翻牌的时候,相应的肯定会有牌被翻转,而假设向上牌少翻一张,向下牌就要多翻一张.奇偶性是不变的,因此仅仅要每次输入张数,维护上下界,最后
