我将数据从PC发送到Android。但我无法在Android中使用UDP接收数据。如何在Android中使用UDP接收数据?如何在android-display上看到收到的数据?任何人都可以帮助我吗?
代码在这里:
public class MainActivity extends Activity {
EditText textOut;
EditText port;
int UDP_SERVER_PORT = 8255;
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
// setContentView(R.layout.main);
try {
int port = UDP_SERVER_PORT;
Log.d("UDP", "Connecting..");
DatagramSocket clientsocket = new DatagramSocket(port);
byte[] receivebuf = new byte[1024];
DatagramPacket receivepacket =
new DatagramPacket(receivebuf,receivebuf.length);
clientsocket.receive(receivepacket);
String modifiedSentence = new String(receivepacket.getData());
System.out.println("FROM SERVER:" + modifiedSentence);
clientsocket.close();
} catch (Exception e) {
Log.e("UDP", "C: Error", e);
}
};
}

为了查看收到的数据,让我们假设数据转换为字符串,然后您需要一个视图来设置其值等于接收的数据。这对你有意义吗?
