我正在制作某种由Android应用程序控制的记分牌。
我开始将数据发送到服务器，但我尝试在我的JFrame和我的Android应用上同步得分，但它无效。
无法理解为什么它不起作用，我可以从应用程序向服务器发送数据，但不能倒退，这是代码：
public class server {
private static ServerSocket serverSocket;
private static Socket clientSocket;
private static InputStreamReader inputStreamReader;
private static BufferedReader bufferedReader;
private static BufferedOutputStream bufferedOutputStream;
private static OutputStreamWriter outputStreamWriter;
private static String message;
public String ipadd;
public String ip;
public controller control;
public pantalla Controlador;
public void run() {
try {
serverSocket = new ServerSocket(4444);
} catch (IOException e) {
System.out.println("Nope Port!");
}
while (true) {
try {
clientSocket = serverSocket.accept();
ipadd = String.valueOf(clientSocket.getInetAddress());
ipadd = ipadd.substring(1, (ipadd.length()));
controller.ipAddress.setText("IP: " + ipadd);
inputStreamReader = new InputStreamReader(clientSocket.getInputStream());
bufferedReader = new BufferedReader(inputStreamReader);
message = bufferedReader.readLine();
OutputStream os = clientSocket.getOutputStream();
OutputStreamWriter osw = new OutputStreamWriter(os);
BufferedWriter bw = new BufferedWriter(osw);
bw.write(controller.txtRedScore2.getText());
bw.flush();
switch (message) {
case "redUp":
controller.btnUpRed.doClick();
break;
case "redDown":
controller.btnDownRed.doClick();
break;
case "blueUp":
controller.btnUpBlue.doClick();
break;
case "blueDown":
controller.btnDownBlue.doClick();
break;
case "update":
controller.btnStart.doClick();
break;
case "x1":
controller.tglByOne.doClick();
break;
case "x5":
controller.tglByFive.doClick();
break;
case "x10":
controller.tglByTen.doClick();
break;
case "x20":
controller.tglByTwenty.doClick();
break;
case "x50":
controller.tglByFifty.doClick();
break;
}
inputStreamReader.close();
clientSocket.close();
} catch (IOException ex) {
System.out.println("Nope!!" + ex);
}
}
}
}
现在我的Android应用程序
