Android手机蓝牙通信设计 RFCOMM协议客户端+语音传送与接收

手机蓝牙通信设计RFCOMM协议客户端+语音传送与接收最近作相关蓝牙RFCOMM协议的东西，下面类主要是针对蓝牙串口协议的客户端，其中包含了设备的搜索，服务的搜索，以及MMAPI函数的应用，希望通过这个类，能让初学者掌握基本的设备的搜索，服务的搜索，和蓝牙串口协议以及录音和语音发送播放等：注意HelloMidlet midlet为一个基础设计的界面类，用来调用ClientBox 类import java.io.DataInputStream;import java.io.DataOutputStream;import java.io.IOException;import java.io.*;import java.util.V ector;import javax.microedition.io.Connector;import javax.microedition.io.StreamConnection;import mand;import mandListener;import javax.microedition.lcdui.Displayable;import javax.microedition.lcdui.Form;import javax.microedition.lcdui.Gauge;import javax.microedition.lcdui.StringItem;import javax.microedition.lcdui.TextField;//jsr082 APIimport javax.bluetooth.BluetoothStateException;import javax.bluetooth.DeviceClass;import javax.bluetooth.DiscoveryAgent;import javax.bluetooth.DiscoveryListener;import javax.bluetooth.LocalDevice;import javax.bluetooth.RemoteDevice;import javax.bluetooth.ServiceRecord;import javax.bluetooth.UUID;import hello.HelloMidlet;import java.io.InputStream; //import javax.microedition.media.*;import javax.bluetooth.DataElement;/*** 客户端GUI*/public class ClientBox extends Form. implements Runnable, CommandListener, DiscoveryListener {//字串输入框TextField input = new TextField("开始搜索", "", 100, TextField.ANY); //编辑框Command com_1 = new Command("开始通话", Command.SCREEN, 0);Command com_2 = new Command("停止通话", Command.SCREEN, 0);// StringItem result = new StringItem("", "");private DiscoveryAgent discoveryAgent;StreamConnection conn;private UUID[] uuidSet;//响应服务的UUID//GUIDprivate static final UUID ECHO_SERVER_UUID = new UUID( "000050020000100080000002ee000001", false);//private static final UUID ECHO_SERVER_UUID = new UUID( "F0E0D0C0B0A000908070605040302010", true);private static final int[] attrSet = {0x0100};//return service name attribute//相应通话按钮的实例private PrimeThread mainThread;//设备集合V ector devices = new V ector();//服务集合V ector records = new V ector();//服务搜索的事务id集合int[] transIDs;HelloMidlet midlet;public ClientBox(hello.HelloMidlet midlet) {super("");this.midlet = midlet;//this.append(result);this.addCommand(new Command("取消", Command.EXIT, 1));this.addCommand(com_1);this.addCommand(com_2);this.append(input);this.setCommandListener(this);new Thread(this).start();}public void commandAction(Command arg0, Displayable arg1) {if (arg0.getCommandType() == Command.EXIT) {if( mainThread!=null)mainThread.distroy();this.midlet.exitMIDlet(); //midlet.showMainMenu();}else if (arg0 == com_1) {input.setString("通话开始");Thread fetchThread = new Thread() {public void run() {for (int i = 0; i < records.size(); i++) {ServiceRecord sr = (ServiceRecord) records.elementAt(i);javax.bluetooth.DataElement de = (DataElement)sr.getAttributeV alue(0x0100);String serverName = (String)de.getV alue();/*if(pareTo("CKCService") < 0) {continue ;} else if (pareTo("CKCService") > 0){} else {}if( !serverName.equals("CKCService") ){continue ;}*/if (accessService(sr)) {break;}}}};fetchThread.start();} else {if(mainThread != null){mainThread.distroy();}input.setString("通话结束");}}private boolean accessService(ServiceRecord sr) {boolean result = false;try {String url = sr.getConnectionURL(ServiceRecord.NOAUTHENTICA TE_NOENCRYPT, false);conn = (StreamConnection) Connector.open(url); //mainThread = new PrimeThread(conn,this);mainThread.start();result = true;}catch (IOException e) {}return result;}public void showInfo( String s) {this.input.setString(s);}public synchronized void run() {//发现设备和服务的过程中，给用户以GaugeGauge g = new Gauge(null, false, Gauge.INDEFINITE, Gauge.CONTINUOUS_RUNNING);this.append(g);showInfo("蓝牙初始化...");boolean isBTReady = false;try {LocalDevice localDevice = LocalDevice.getLocalDevice();discoveryAgent = localDevice.getDiscoveryAgent();isBTReady = true;}catch (Exception e) {e.printStackTrace();}if (!isBTReady) {showInfo("蓝牙不可用");//删除Gaugethis.delete(1);return;}uuidSet = new UUID[2];//标志我们的响应服务的UUID集合uuidSet[0] = new UUID(0x0100);// uuidSet[0] =ECHO_SERVER_UUID;uuidSet[1] = ECHO_SERVER_UUID;try {discoveryAgent.startInquiry(DiscoveryAgent.GIAC, this);}catch (BluetoothStateException e) {}try {//阻塞,由inquiryCompleted()回调方法唤醒wait();}catch (InterruptedException e1) {e1.printStackTrace();}if (devices.size() > 0) {RemoteDevice rd1 = (RemoteDevice) devices.elementAt(0);String name = "";try {name = rd1.getFriendlyName(true);} catch (IOException ex) {ex.printStackTrace();}showInfo("设备搜索完毕,共找到" + devices.size() + "个设备,Name= " + name.toString() + " 开始搜索服务");}else {showInfo("设备搜索完毕,共找到0个设备,不能提供服务。
