下面是服务端代码

try {
//创建服务器端Socket,绑定端口，监听
System.out.println("*****服务器启动了!等待客户端连接!*****");
InetAddress addr1 = InetAddress.getLocalHost();
System.out.println("服务器名称地址："+addr1);
ServerSocket serverScoket=new ServerSocket(7777);
Socket socket=serverScoket.accept();
System.out.println("*****成功连接*****");
//接受数据
InputStream is=socket.getInputStream();
InputStreamReader isr=new InputStreamReader(is);
BufferedReader br=new BufferedReader(isr);
String info=null;
info=br.readLine();
//判断控制字符串 模拟键盘输入
while(info!=null){
if(info.equals("fullscreen")){
robot.keyPress(KeyEvent.VK_F6);
robot.keyRelease(KeyEvent.VK_F6);
System.out.println("*****全屏执行*****");
}else if(info.equals("next")){
robot.keyPress(KeyEvent.VK_N);
robot.keyRelease(KeyEvent.VK_N);
System.out.println("*****下一页执行*****");
}else if(info.equals("last")){
robot.keyPress(KeyEvent.VK_P);
robot.keyRelease(KeyEvent.VK_P);
System.out.println("*****上一页执行*****");
}else if(info.equals("stop")){

robot.keyRelease(KeyEvent.VK_ESCAPE);
System.out.println("*****停止执行*****");
}else if(info.equals("final")){
socket.shutdownInput();
isr.close();
is.close();
socket.close();
serverScoket.close();
System.out.println("*****服务器已关闭*****");
}
}
}
catch (IOException e) {
// TODO 自动生成的 catch 块
e.printStackTrace();
}
}
private static Robot robot = null;
public void RobotDemo()
{
try
{
robot = new Robot();
}
catch (AWTException e)
{
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}
现在就是连接之后 会打印出连接成功 但是安卓上 按上一页下一页之类的按钮没有反应 按结束也没反应 求高手看看
------解决思路----------------------
由于没有把发送信息的代码放到服务中,在页面中调用最好还是随时连接随时断开.
发送信息的变量pw显然不是建立连接时那个pw,为何没有崩溃呢
发送信息的代码我认为也需要放到线程中,主线程不允许操作网络
------解决思路----------------------
debug啊，应该是info=br.readLine();的时候就返回null了
