Android 这段UDP客户端的代码为什么发不出去？我在电脑上开起一个UDP服务端都收不到数据

try
{
EditText txtPort = (EditText)findViewById(R.id.editTxtPort);
int port = Integer.parseInt(txtPort.getText().toString(), 10);

EditText txtIP = (EditText)findViewById(R.id.editTxtIP);
String ip = txtIP.getText().toString();

EditText txtContent = (EditText)findViewById(R.id.editTxtContent);
String content = txtContent.getText().toString();

//int port = 1658;
//String ip = "127.0.0.1";
//String content = "test";
//创建一个DatagramSocket的对象
DatagramSocket socket = new DatagramSocket(port);
//创建一个IntAddress serverAddress
InetAddress serverAddress = InetAddress.getByName(ip);

byte[] data= content.getBytes();

DatagramPacket packet = new DatagramPacket(data,data.length,serverAddress,port);

try
{
socket.send(packet);
}
catch (IOException e)
{
// TODO Auto-generated catch block
e.printStackTrace();
}
}
catch (SocketException e)
{
// TODO Auto-generated catch block
e.printStackTrace();
} catch (UnknownHostException e)
{
// TODO Auto-generated catch block
e.printStackTrace();
}
}

地址设置为 10.0.2.2 试试。

就是 java 的udp操作，搜一下应该会有很多

你如果是用电脑的虚拟机的话可能不行，因为那个地址被占用了127.0.0.1那个
