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.docx

1、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，但是通过电脑控制毕竟不方便，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（Android）、Windows Mobile，对比了一下，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基本是一样的，也就没什么意思了，最后决定选择目前正火的Android手机作为控制平台。Android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Jav

2、a语言开发手机端的控制程序，由于之前对Android的蓝牙通信这块涉及不多，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Android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Android项目，修改布局文件main.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

3、少，否则将无法使用安卓手机的蓝牙功能。权限声明如下：打开AndroidManifest.xml文件，修改代码如下： 其中红色、加粗部分就是要添加的权限声明。然后编写Activity中的执行代码，这些代码的作用就是发送指令，控制小车的运动。代码如下：package com.ThinBTClient.www;import android.app.Activity;import android.os.Bundle;import java.io.IOException;import java.io.OutputStream;import java.util.UUID;import android.ap
