公司最近需要往智能家居方面发展，需要用到UDP协议传输数据，在网上找到了一些资料，但是发现传输中文的时候有乱码的现象，经过我多番捣鼓，终于解决了这个问题，下面贴上关键代码

客户端:

public class UDPClient {
private static final int SERVER_PORT = 6000;
private DatagramSocket dSocket = null;
private String msg;
private String ip; public UDPClient(String msg, String ip) {
super();
this.msg = msg;
this.ip = ip;
} public void send() {
try {
dSocket = new DatagramSocket();
byte[] bys = msg.getBytes();
int len = bys.length;
DatagramPacket dp = new DatagramPacket(bys, len, InetAddress.getByName(ip), SERVER_PORT);
dSocket.send(dp);
// }
} catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
} finally {
dSocket.close();
}
}
}

服务端:

public class UDPServer implements Runnable {
private static final int PORT = 6000;
private byte[] msg = new byte[2048];
Context context;public UDPServer(Context context) {
this.context = context;
}@Override
public void run() {
DatagramSocket s;
try {
s = new DatagramSocket(PORT);
while (true) {
int len = msg.length;
DatagramPacket dp = new DatagramPacket(msg, len);
s.receive(dp);
byte[] byc = dp.getData();
int len2 = dp.getLength();
String ss = new String(byc, 0, len2);
Message msg = Message.obtain();
msg.what = 0x789;
msg.obj = ss;
MainActivity.handler.sendMessage(msg);
}
} catch (Exception e) {
e.printStackTrace();
}
}
}
