传输加速度计值TCP

Question

我试图通过tcp套接字来读取加速度计值并通过它传输它。 此代码可以读取加速度计值并可以通过tcp进行通信，但我无法通过tcp套接字发送加速度计值。

这是Stream.java（活动）

TextView textView;
//String SIP="10.118.33.132";
int SP=5000;
 float ay;
 String TAG="main";
private SensorManager sensorManager;
GetAccVal myval = new GetAccVal();


@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_stream);
    textView = (TextView) findViewById(R.id.textView1);
    Bundle extra = getIntent().getExtras();

    String SIP = extra.getString("SIP_1");
    Log.d(TAG,"SIP1 ex:"+SIP);

    Runnable ConnectClient = new Client(SIP);
    new Thread(ConnectClient).start();
    textView.setText("Thread Started");

    sensorManager=(SensorManager)getSystemService(SENSOR_SERVICE);
    // add listener. The listener will be HelloAndroid (this) class
    sensorManager.registerListener(this,sensorManager.getDefaultSensor(Sensor.TYPE_ACCELEROMETER),SensorManager.SENSOR_DELAY_NORMAL);

}

@Override
   public void onAccuracyChanged(Sensor arg0, int arg1) {
   }


@Override
   public void onSensorChanged(SensorEvent event) {
        if (event.sensor.getType()==Sensor.TYPE_ACCELEROMETER){

                    ay=event.values[1];
                   // textView.setText("y="+ay);
                   myval.setVal(ay);

                  //  Log.d(TAG,"Sensor X=:"+ay);
                 //   String sn = myval.getsen();
                    textView.setText("y="+ay);

            }

}

}

Client.java

public class Client implements Runnable {

String SIP_1;
int SP=5000;
Socket s;
int a=0;
boolean SF=false;
String TAG = "Connection";
PrintWriter out;

 public Client(String SIP_1) {
     this.SIP_1=SIP_1;      
   }

public void run() {

    GetAccVal myval = new GetAccVal();
    myval.setip(SIP_1);

    }
}

GetAccVal.java

public class GetAccVal {
public float y,y1,my;
String ecosen,ip;
String TAG="DATA";
boolean connected=false;

public void setVal(float y){

    this.y=y;

    if(connected){
    try{
    Log.d(TAG,"setval y=:"+y);
    Log.d(TAG,""+y);
    out.println(y);

    }
catch (Exception e) {
        e.printStackTrace();
    }

    }
}

  public void setip(String ip){

         this.ip=ip;
      Log.d(TAG,"ip= :"+ip);

      try{               
             InetAddress serverAddr = InetAddress.getByName(ip);
             s = new Socket(serverAddr, SP);


             out = new PrintWriter(new BufferedWriter(
                        new OutputStreamWriter(s.getOutputStream())),
                        true);

      connected=true;
         }

         catch (UnknownHostException e1) {
            e1.printStackTrace();
            Log.d(TAG,"EXIT ex:"+e1);
        } catch (IOException e1) {
            e1.printStackTrace();
            Log.d(TAG,"EXIT ex:"+e1);

        }

}
