Android网络——C/S通信

Server：

public class Server {
public static void main(String[] args) throws IOException {
ServerSocket server = new ServerSocket(8081);
Socket client = server.accept();
InputStream i = client.getInputStream();
BufferedReader in = new BufferedReader(new InputStreamReader(i));
String str = in.readLine();
System.out.println(str);
PrintWriter out = new PrintWriter(client.getOutputStream());
out.println("has receive.\n");
out.close();
in.close();
client.close();
}

}

Client：

public class Cs extends Activity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
findViewById(R.id.tv).setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
new Thread() {
public void run() {
try {
InetAddress localHost = InetAddress.getLocalHost();
System.out.println(localHost.toString());
Socket client = new Socket("192.168.1.45", 8081);
PrintWriter out = new PrintWriter(client.getOutputStream());
out.println("88888888888\n");
out.flush();
BufferedReader in = new BufferedReader(new InputStreamReader(client.getInputStream()));
System.out.println(in.readLine());
out.close();
in.close();
client.close();
System.out.println("client endl....");

} catch (Exception e) {
}
};
}.start();
}
});

}

}
