我是新手Socket，我尝试在同一个应用程序上编写服务器和客户端代码只是为了看看它是如何工作的。
代码：
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
((Button)this.findViewById(R.id.bouton1)).setOnClickListener(this);
}
public void onClick(View v) {
TCPServer server = new TCPServer();
TCPClient client = new TCPClient();
server.start();
client.start();
}
public class TCPServer extends Thread {
@Override public void run() {
try {
ServerSocket s = new ServerSocket(8080,0,InetAddress.getLocalHost());
Socket cli = s.accept();
byte[] b = new byte[512];
int n;
InputStream is = cli.getInputStream();
while((n=is.read(b))>0){
Log.d("TCPServer",new String(b));
if(new String(b).contains("\r\n\r\n"))break;
b = new byte[512];
}
OutputStream os = cli.getOutputStream();
os.write("Hello".getBytes());
} catch (Exception e) {
e.printStackTrace();
}
}
}
public class TCPClient extends Thread {
@Override public void run() {
try {
Socket s = new Socket(InetAddress.getLocalHost().getHostAddress(),8080);
//Socket s = new Socket("www.google.com",80);
//Log.i("",s.getLocalAddress().getHostAddress());
byte[] b = new byte[512];
int n;
if (s.isConnected()) {
OutputStream os = s.getOutputStream();
os.write("Hi How are you \r\n\r\n".getBytes());
InputStream is = s.getInputStream();
while((n=is.read(b))>0){
Log.d("TCPClient",new String(b));
b = new byte[512];
}
}
s.close();
} catch (Exception e) {
e.printStackTrace();
}
}
}
代码工作正常，但只是我第一次点击我的按钮。错误是java.net.BindException: Address already in use。
