Question

我正在尝试使用android java编写一个带有AIDE的应用程序，我需要的最终结果是一个使用滑块的应用程序，当我释放滑块时，与滑块位置关联的数字IP＆＃34;在这里插入IP＆＃34;和端口＆＃34;在这里插入端口＆＃34;，但是我从不同的类中提取值，我需要它来写入方法内部的值，如何将变量拉出方法？

public void sendPort(int port){ 
    //TO-DO take port variable and input into sendIp
}

里面的

public void sendIp(String ip){
    //needs the port variable in here
}

但是当我尝试时，它告诉我我的代码中有错误并且无法编译，直到错误得到修复，我得到的错误说有一个＆＃34; Missing＆＃39; }＆＃39;＆＃34;之后是一个＆＃34;意外的＆＃39;}＆＃39;＆＃34;。是否存在类似公共空白或检测到大括号的方法的脚本？菜单的代码

public void showChangeLangDialog() {
    AlertDialog.Builder dialogBuilder = new AlertDialog.Builder(this);
    LayoutInflater inflater = this.getLayoutInflater();
    final View dialogView = inflater inflate(R.layout.custom_dialog, null);
    dialogBuilder.setView(dialogView);

        final EditText ip = (EditText) dialogView.findViewById(R.id.edit1);
        final EditText edt = (EditText) dialogView.findViewById(R.id.edit2);

        dialogBuilder.setTitle("Custom dialog");
        dialogBuilder.setMessage("Enter text below");
        dialogBuilder.setPositiveButton("Done", new DialogInterface.OnClickListener() {
                public void onClick(DialogInterface dialog, int whichButton) {
                    String port = edt.getText().toString();
                    mTcpClient.sendIp(String.valueOf(ip));
                    mTcpClient.sendPort(Integer.valueOf(port));
                    //do something with edt.getText().toString();
                }
            });
        dialogBuilder.setNegativeButton("Cancel", new DialogInterface.OnClickListener() {
                public void onClick(DialogInterface dialog, int whichButton) {
                    //pass
                }
            });
        AlertDialog b = dialogBuilder.create();
        b.show();
    }

检索变量并发送滑块位置编号的代码

public void sendMessage(String message){
        if (out != null && !out.checkError()) {
            out.println(message);
            out.flush();
            out.close();
        }
    }
    public void sendPort(int port){
        Log.i("TCPClient", "Recieved Port");
        int SERVERPORT = 0 + port;

        public void sendIp(String ip){
            Log.i("TCPClient", "Recieved IP");
            String SERVERIP = "" + ip; 

        try {

            InetAddress serverAddr = InetAddress.getByName(SERVERIP);
            Log.e("TCP Client", "C: Connecting...");
            Socket socket = new Socket(serverAddr, SERVERPORT);
            try {
//send the message to the server
                out = new PrintWriter(new BufferedWriter(new OutputStreamWriter(socket.getOutputStream())), true);
                Log.e("TCP Client", "C: Sent.");
                Log.e("TCP Client", "C: Done.");
//receive the message which the server sends back
                in = new BufferedReader(new InputStreamReader(socket.getInputStream()));
//in this while the client listens for the messages sent by the server
                while (mRun) {
                    serverMessage = in.readLine();
                    if (serverMessage != null && mMessageListener != null) {
//call the method messageReceived from MyActivity class
                        mMessageListener.messageReceived(serverMessage);
                    }
                    serverMessage = null;
                }
                Log.e("RESPONSE FROM SERVER", "S: Received Message: '" + serverMessage + "'");
            } catch (Exception e) {
                Log.e("TCP", "S: Error", e);
            } finally {
//the socket must be closed. It is not possible to reconnect to this socket
// after it is closed, which means a new socket instance has to be created.
                socket.close();
            }
        } catch (Exception e) {
            Log.e("TCP", "C: Error", e);
        }
    }

//Declare the interface. The method messageReceived(String message) will must be implemented in the MyActivity
//class at on asynckTask doInBackground
    public interface OnMessageReceived {
        public void messageReceived(String message);
    }
    }

我从另一个类的菜单中抓取端口和IP的值，你看到的第二个脚本是一个不是活动的类，它只是一个背景类。

在Java中，您无法在另一个方法中声明新方法。如果你需要两个单独的方法，在你的类中单独声明它们，然后在另一个中调用一个，如下所示：

public void sendPort(int port){ 
    //some sort of code here
} 

public void sendIp(String ip){
    //some code 
    sendPort(portAsInt);
    //more code
}

如果您不需要两种不同的方法，那么只需在sendPort方法中包含sendIp方法中的逻辑。

在第一个内部有另一个公共空白
