Question

我试图通过TCP连接连接两个Android设备，我已经写了服务器和客户端代码....但是当我运行它时，它在屏幕上看起来什么也没有。我真的不知道自己做错了什么。我在清单中提到了互联网许可我检查了客人的IP地址附：对不起，我的英语不好客户代码：

  package mybum.buff.client;

  import android.app.*;
  import android.os.*;
  import android.view.*;
  import android.widget.*;
  import java.net.*;
  import java.io.*;
  import android.view.View.*;

public class MainActivity extends Activity
 {    private static final int TCP_PORT=21111;


 private Button startcon, stopcon;
 private TextView txt;

/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState)
{
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);
    startcon = (Button)findViewById(R.id.start);
    stopcon = (Button)findViewById(R.id.stop);
    Thread thread1 = new Thread(new Runnable(){

            @Override
            public void run()
            {  try{
                runserver();
                }
                catch(Exception e){}
            }


    });
    thread1.start();

}
private void runserver(){
    txt = (TextView)findViewById(R.id.text1);
    try
    {   
        Socket s = new Socket("192.168.43.148", TCP_PORT);

        BufferedReader  read =new  BufferedReader(new InputStreamReader(s.getInputStream()));
        BufferedWriter write = new BufferedWriter(new OutputStreamWriter(s.getOutputStream()));

        String outmsg ="Hi, I'm the client " +System.getProperty("line.separator");
        write.write(outmsg);
        write.flush();
        String inmsg = read.readLine()+System.getProperty("line.separator")+;
        txt.setText(inmsg);

        s.close();

    }
    catch (IOException e)
    {}

}
 }

服务器代码： package blam.gbn.server;

    import android.app.*;
    import android.os.*;
    import android.view.*;
    import android.widget.*;
    import java.net.*;
    import java.io.*;
    import android.view.View.*;

     public class MainActivity extends Activity
    {       Button start, stop;
private TextView text1;
private ServerSocket ss;
private Socket s;
public static final  int TCP_PORT=21111;
private BufferedReader read;
private BufferedWriter write;
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState)
{
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);
    start = (Button)findViewById(R.id.start);
    stop = (Button)findViewById(R.id.stop);
    text1 = (TextView)findViewById(R.id.text);

    Thread thread1 = new Thread(new Runnable(){

            @Override
            public void run()
            {
                try{
             runserver();

             }
             catch(Exception e){}

            }


            });
       thread1.start();







}
private void runserver(){

     ss=null;
    try
    {   

        ss = new ServerSocket(TCP_PORT);
         text1.setText("2");
        s = ss.accept();
         text1.setText("3");
        read = new BufferedReader(new InputStreamReader(s.getInputStream()));
        write = new BufferedWriter(new OutputStreamWriter(s.getOutputStream()));
        String inmsg = "Client : " + read.readLine()+ System.getProperty("line.separator");
        text1.append(inmsg);
        String outmsg = "Hi, I'm the server" + System.getProperty("line.separator");
        write.write(outmsg);
        write.flush();
        s.close();
        if (ss!=null){
            ss.close();
        }
    }
    catch (IOException e)
    {}


}

}
