android端和pc端使用usb进行socket通信，其中android是服务器端，pc是客户端。如何实现安卓端输入的数据通过按钮发送到pc端？
部分源码如下：
主类androidService.java
/**
* 设置：android手机
*
*/
public class androidService extends Service {
public static final String TAG = "TAG";
public static Boolean mainThreadFlag = true;
public static Boolean ioThreadFlag = true;
ServerSocket serverSocket = null;
final int SERVER_PORT = 10086;
File testFile;
private sysBroadcastReceiver sysBR;
@Override
public void onCreate() {
super.onCreate();
Log.v(TAG, Thread.currentThread().getName() + "---->" + " onCreate");
//创建内部类sysBroadcastReceiver 并注册registerReceiver
sysRegisterReceiver();
new Thread() {
public void run() {
doListen();
};
}.start();
}
private void doListen() {
Log.d(TAG, Thread.currentThread().getName() + "---->"
+ " doListen() START");
serverSocket = null;
try {
Log.d(TAG, Thread.currentThread().getName() + "---->"
+ " doListen() new serverSocket");
serverSocket = new ServerSocket(SERVER_PORT);
boolean mainThreadFlag = true;
while (mainThreadFlag) {
Log.d(TAG, Thread.currentThread().getName() + "---->"
+ " doListen() listen");
Socket client = serverSocket.accept();
new Thread(new ThreadReadWriterIOSocket(this, client)).start();
}
} catch (IOException e1) {
Log.v(androidService.TAG, Thread.currentThread().getName()
+ "---->" + "new serverSocket error");
e1.printStackTrace();
}
}
/* 创建内部类sysBroadcastReceiver 并注册registerReceiver */
private void sysRegisterReceiver() {
Log.v(TAG, Thread.currentThread().getName() + "---->"
+ "sysRegisterReceiver");
sysBR = new sysBroadcastReceiver();
/* 注册BroadcastReceiver */
IntentFilter filter1 = new IntentFilter();
/* 新的应用程序被安装到了设备上的广播 */
filter1.addAction("android.intent.action.PACKAGE_ADDED");
filter1.addDataScheme("package");
filter1.addAction("android.intent.action.PACKAGE_REMOVED");
filter1.addDataScheme("package");
registerReceiver(sysBR, filter1);
}
/* 内部类：BroadcastReceiver 用于接收系统事件 */
private class sysBroadcastReceiver extends BroadcastReceiver {
@Override
public void onReceive(Context context, Intent intent) {
String action = intent.getAction();
if (action.equalsIgnoreCase("android.intent.action.PACKAGE_ADDED")) {
// ReadInstalledAPP();
} else if (action
.equalsIgnoreCase("android.intent.action.PACKAGE_REMOVED")) {
// ReadInstalledAPP();
}
Log.v(TAG, Thread.currentThread().getName() + "---->"
+ "sysBroadcastReceiver onReceive");
}
}
@Override
public void onDestroy() {
super.onDestroy();
// 关闭线程
mainThreadFlag = false;
ioThreadFlag = false;
// 关闭服务器
try {
Log.v(TAG, Thread.currentThread().getName() + "---->"
+ "serverSocket.close()");
serverSocket.close();
} catch (IOException e) {
e.printStackTrace();
}
Log.v(TAG, Thread.currentThread().getName() + "---->"
+ "**************** onDestroy****************");
}
@Override
public void onStart(Intent intent, int startId) {
Log.d(TAG, Thread.currentThread().getName() + "---->" + " onStart()");
super.onStart(intent, startId);
}
@Override
public IBinder onBind(Intent arg0) {
Log.d(TAG, " onBind");
return null;
}
}
