我目前正在开发Android中的tcp客户端.我想将我的Android设备连接到计算机上的tcp服务器,并每2秒接收一次数据.问题是由于我在tcp客户端中实现的while循环,我正在关闭我的应用程序.我尝试以不同的方式编写将使tcp客户端检查服务器套接字的循环,但没有成功.如何制作一个循环来检查服务器套接字而不关闭力？

这是我目前正在使用的代码:

    public class Connection implements Runnable {
    @Override
    public void run() {         
        try {                    
            sk=new Socket(server,port);
            viewsurface.setText("connected");       
            flag = true;
        } catch (UnknownHostException e) {      
            viewsurface.setText("failed 1 socket");
            flag = false;
        } catch (IOException e) {                   
            viewsurface.setText("failed 2 socket");
            flag = false;
        }

        while (flag == true){               
            try {
                checkin = sk.getInputStream();
                checkint = checkin.available();

                if (checkint > 0){
                    try {
                        BufferedReader in = new BufferedReader(new InputStreamReader(sk.getInputStream()));
                        received = in.readLine();
                        viewsurface.setText(received);

                    } catch (IOException e) {
                        viewsurface.setText("failed to receive"); …
