实时向服务器发送数据

Question

我试图为Android制作一个远程鼠标应用程序（通过TCP从电话上控制PC上的鼠标）。在客户端（android）上，我在UIThread中实现了OnTouchListener，但客户端套接字和IO在另一个线程中运行。服务器接收坐标，但只有一次，即使客户端正在发送一段时间（true）循环，并且将手指移动到手机显示屏上。它应该永久发送最近的坐标，不仅是第一个坐标。

public class MainActivity extends Activity implements OnTouchListener { 
private ServerSocket ss; 
private Socket socket; 
TextView tv; 
String x, y; 
private static final int SERVERPORT = 444; 
private static final String SERVER_IP = "192.168.1.3"; 

@Override 
protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.activity_main); 
    tv = (TextView) findViewById(R.id.textView1); 
    RelativeLayout l = (RelativeLayout) findViewById(R.id.myView); 
    l.setOnTouchListener(this); 
} 

class Worker implements Runnable{ 

    PointF point; 
    public Worker(PointF point) { 
     this.point = point; 
    } 
    @Override 
    public void run() { 
     try { 
      InetAddress adress = InetAddress.getByName(SERVER_IP); 
      socket = new Socket("192.168.1.3", SERVERPORT); 
      BufferedWriter obf = new BufferedWriter(new OutputStreamWriter(socket.getOutputStream())); 

       obf.write(point.x+" "+point.y); 
       obf.flush(); 
       obf.close(); 


     } catch (UnknownHostException e) { 
      // TODO Auto-generated catch block 
      e.printStackTrace(); 
     } catch (IOException e) { 
      // TODO Auto-generated catch block 
      e.printStackTrace(); 
     } 
    } 

} 
    ExecutorService executor = Executors.newFixedThreadPool(5); 

@Override 
public boolean onTouch(View v, MotionEvent event) { 
    int action = event.getAction(); 

    switch (action) { 
    case MotionEvent.ACTION_MOVE: 
     x=String.valueOf(event.getX()); 
     y=String.valueOf(event.getY()); 
     tv.setText(x+" + "+y); 
     PointF point = new PointF(event.getX(), event.getY()); 
     executor.execute(new Worker(point)); 
     break; 

    default: 
     break; 
    } 
    return true; 
} 

}

你可以简单地实现这个...

class Worker implements Runnable{ 
    PointF point; 
    public Worker(PointF point) { 
     this.point = point; 
    } 
    @Override 
    public void run() { 

     //send pointf to server here 
    } 

} 
    ExecutorService executor = Executors.newFixedThreadPool(5); 

@Override 
public boolean onTouch(View v, MotionEvent event) { 
    int action = event.getAction(); 

    switch (action) { 
    case MotionEvent.ACTION_MOVE: 

     PointF point = new PointF(event.getX(), event.getY()); 
     executor.execute(new Worker(point)); 
     break; 

    default: 
     break; 
    } 
    return true; 
}
