Android传感器API之：温度传感器SensorTemperature功能源码

个人觉得温度传感器的应用频率应该不会太高，这也是部分Android手机直接将这个功能屏蔽掉的原因所在。不过从创意角度出发，基于这个传感器可以开发出一些有意思的应用，比如手机温度计、室温监测等等。。
个性化的应用就不说了，具体的说实话我也没做，只是把Rexsee的功能源码分享出来，回头要是有应用了再分享。和之前的帖子里提到的一样，Android平台带有大量的传感器功能，相关的原生源码可以在Rexsee的开源社区找到：http://www.rexsee.com/
SensorTemperature功能源码如下

Rexsee貌似贴了很多源码了，能统一汇总整理一篇不？这代码很赞的，帮助极大

我有自己写好了的温度传感器源码，已成功应用，需要的与我联系。。

唉!!!!!!

广告贴》？··


我手机上直接读不到·

要能深入挖掘传感器应用，估计会有另一番天地。
