Android Sensor Development

Android Sensor Development 本文我们说一下Android中的传感器，这对于我们有时候做一些特殊的应用的时候还是需要的，这里我用小米手机下载了一个安兔兔，我们来看下大致的传感器安兔兔上面，有很多的传感器对吧，但是他们大致的其实是分三类，在我们的官方文档上，是这样说的 sen...

我的Android进阶之旅------>Android利用Sensor(传感器)实现水平仪功能的小例

这里介绍的水平仪，指的是比较传统的气泡水平仪，在一个透明圆盘内充满液体，液体中留有一个气泡，当一端翘起时，该气泡就会浮向翘起的一端。利用方向传感器返回的第一个参数，实现了一个指南针小应用。我...

我的Android进阶之旅------>Android利用Sensor(传感器)实现指南针功能

首先来说一说该指南针的实现思路：程序先准备一张指南针图片，该图片上方向指针指向北方。接下来开发一个检测方向的传感器，程序检测到手机顶部绕Z轴转过多少度，让指南针图片反向转多少度即可。由此可见指南针应用只要在界面中添加一张图片，并让图片总是反向转过反向传感器返回的第一个角度值即可。下面介绍一下方向...
