成功实现手机蓝牙控制智能小车机器人视频+程序源代码Android

1、word但是通过电脑控制毕竟上次成功实现了通过笔记本电脑蓝牙来控制智能小车机器人的运动, 不方便，于是乎本人打算将控制程序移植到手机上。目前主流的手机操作系统有塞班、安卓An droid、Win dows Mobile，比照了一下，首先，塞班是用C+写的，这么多门语言我唯独看到C+就头大，放弃了 ，Windows Moblie其实和之前发的电脑端程序根本是一样的，也就没什么意思了，最后决定选择目前正火的 An droid手机作为控制平台。An droid是个开源的应用，使用Java语言对其编程。于是这次的开发我选用Eclipse作为开发工具，用Java语言开发手机端的控制程序，由于之前对An

2、droid的蓝牙通信这块涉与不多，一开始感觉有点小茫然，而网上也少有这方面的例程，有少数人做出了类似的东西，但 是只传了个视频装X!雪特经过几天的研究，最终确定了手机蓝牙通信其实就是Socket编程，再经过一番编写和调试,昨晚终于大功告成!这是视频:下面开始介绍An droid手机端控制程序的编写：首先打开Eclipse，当然之前的Java开发环境和安卓开发工具自己得先配置好，这里就不多 说了，网上教程一大摞。然后新建一个 An droid项目，修改布局文件 mai n. xml，代码如下： 这个布局文件的效果就是如视频中所示的手机操作界面。然后是权限声明，这一步不能少，否如此将无法使用安卓手

3、机的蓝牙功能。 权限声明如下：打开AndroidManifest.xml 文件，修改代码如下： applicati on an droid:ic on=drawable/ic on an droid:label=stri ng/app_ name vactivity an droid: name=.Thi nBTClie ntan droid:label=stri ng/app_ namevcategory an droid: name=a ndroid.i nten t.category.LAUNCHER /其中红色、加粗局部就是要添加的权限声明。然后编写Activity中的执行代码，这些代
