java - 解析套接字输入字符串

Question

我希望从我的 telnet 套接字输入中解析“艺术家 - 标题”。现在它只显示最后一行“END”。我做错了什么？我是初学者，需要 java.pls 帮助...

我的 Activity 脚本可以工作:

try {
        Socket s = new Socket("10.0.2.2", 5555);


        BufferedReader in = new BufferedReader(new InputStreamReader(s.getInputStream()));
        BufferedWriter out = new BufferedWriter(new OutputStreamWriter(s.getOutputStream(), "ISO8859_1"));



        String on_air = "request.on_air" + System.getProperty("line.separator");
        out.write(on_air);
        out.flush();
        Log.i("TcpClient", "sent: " + on_air);
        String on_airin = in.readLine() + System.getProperty("line.separator");
        Log.i("TcpClient", "received: " + on_airin);
        String metadata = "ao.metadata "+ on_airin + System.getProperty("line.separator"); 
        out.write(metadata);
        out.flush();
        Log.i("TcpClient", "sent2: " + metadata);
        String metadatain = in.readLine() + System.getProperty("line.separator");
        Log.i("TcpClient", "received: " + metadatain);

        String line = in.readLine();
        while (line != null) {

            line = in.readLine();


            System.out.println(line);
            output = (TextView) findViewById(R.id.textView2);
            output.setText(line);





//tv.setText(online + formatedDate );
        output = (TextView) findViewById(R.id.textView1);



s.close();

    }} catch (UnknownHostException e) {
        e.printStackTrace();
    } catch (IOException e) {
        e.printStackTrace();
    }

}

Answer 1

在打印之前执行额外的readLine()。折叠这三行:

String line = in.readLine();
while (line != null) {
    line = in.readLine();

进入

String line = null;
while ((line = in.readLine()) != null) {  

此外，您似乎在 while 循环内关闭了 Socket，这可能会导致问题。
