Question

我的服务有问题。我有3个按钮，第一个呼叫服务，以便在randon获取数字并每隔10秒在文本框中显示它们，第二个按钮呼叫服务，以便在每次按下该按钮时获得rand的数字，最后一个按钮必须停止服务，但我不能当我按下它，当我关闭应用程序并再次打开服务运行自动我不明白！

有我的服务类

public class MyService extends Service{
public static final String NEW_DATA = "com.example.t8ej1.MyService.NEW_DATA";
private static final String stringUrl =
"http://www.imaginaformacion.com/recursos/rand.php";
private static final int updateInterval = 1000;
private Timer updateTimer;
private TimerTask doRefresh;
private String data;
public int service_id;
private IBinder binder = new MyBinder ();

public class MyBinder extends Binder {
MyService getService() {
return MyService.this;
}}

private void updateData() {
    // Nos conectamos al servicio web y obtenemos los datos

    try{

        URL url = new URL(stringUrl);
        HttpURLConnection httpURLConnection =(HttpURLConnection) url.openConnection();
        int responseCode = httpURLConnection.getResponseCode();
        if(responseCode == HttpURLConnection.HTTP_OK){
            InputStream in = httpURLConnection.getInputStream();
            BufferedReader reader = new BufferedReader(new InputStreamReader(in));
            data= reader.readLine();
            in.close();
            announceData();


        }

    } 

    catch( MalformedURLException e){
        Log.e("Service", e.getMessage());
    }catch(IOException e){
        Log.e("Service", e.getMessage());
    }
}

private void announceData() {
    // Lanzamos el broadcast con el intent y los datos

    Intent intent = new Intent(NEW_DATA);
    intent.putExtra("data", data);
    sendBroadcast(intent);
}

@Override
public IBinder onBind(Intent intent) {
    // TODO Auto-generated method stub
    return binder;
}



@Override
public int onStartCommand(Intent intent, int flags, int startId) {
    // TODO Auto-generated method stub
    // Creamos el Timer y el TimerTask

    service_id=startId;
    updateTimer = new Timer();
    doRefresh = new TimerTask() {

        @Override
        public void run() {
            // TODO Auto-generated method stub              
            updateData();
        }
    };
    // Lo programamos para que se lance cada updateInterval milisegundos
    updateTimer.scheduleAtFixedRate(doRefresh, 0, updateInterval);
    // Queremos que el servicio esté siempre encendido


    return Service.START_STICKY;
}



@Override
public void onDestroy() {
    // TODO Auto-generated method stub
    Log.e("mm", "4444");
    super.onDestroy();
}


public String getData() {
    return data;
    }}

有我的活动课

public class Service extends Activity {
private MyServiceReceiver myReceiver;
private MyService myService;
TextView txtManual;
TextView txtAuto;

    @Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_service);

    bindService(new Intent(Service.this, MyService.class),
            myConnection,
            Context.BIND_AUTO_CREATE);

    IntentFilter filter;
    filter = new IntentFilter(MyService.NEW_DATA);
    myReceiver = new MyServiceReceiver();
    registerReceiver(myReceiver, filter);


txtAuto = (TextView) findViewById(R.id.txtAuto);
txtManual = (TextView) findViewById(R.id.txtManual);

Button cmdStart = (Button) findViewById(R.id.cmdStart);
Button cmdRefresh = (Button) findViewById(R.id.cmdRefresh);
Button cmdStop = (Button) findViewById(R.id.cmdStop);

cmdStop.setOnClickListener(new OnClickListener() {

    @Override
    public void onClick(View v) {
        // TODO Auto-generated method stub


        unbindService(myConnection);

        stopService(new Intent(Service.this, MyService.class));         


    }
});

cmdRefresh.setOnClickListener(new OnClickListener() {
    @Override

    public void onClick(View v) {
    txtManual.setText(myService.getData());
    }
    });


cmdStart.setOnClickListener(new OnClickListener() {
    @Override
    public void onClick(View v) {
        // TODO Auto-generated method stub

        startService(new Intent(Service.this, MyService.class));
    }
});


}

    private ServiceConnection myConnection = new ServiceConnection () {

        @Override
        public void onServiceConnected(ComponentName name, IBinder service) {
            // TODO Auto-generated method stub
            myService = ((MyService.MyBinder) service).getService();    
        }

        @Override
        public void onServiceDisconnected(ComponentName name) {
            // TODO Auto-generated method stub
            myService=null;
        }


        };


public class MyServiceReceiver extends BroadcastReceiver {

    @Override
    public void onReceive(Context context, Intent intent) {
        // TODO Auto-generated method stub
    txtAuto.setText(intent.getStringExtra("data")); 



    }

}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
    // Inflate the menu; this adds items to the action bar if it is present.
    getMenuInflater().inflate(R.menu.main, menu);
    return true;
}
@Override



protected void onPause() {
    // TODO Auto-generated method stub
    //unregisterReceiver(myReceiver);
    super.onPause();
}

@Override
protected void onDestroy() {
    // TODO Auto-generated method stub

    super.onDestroy();
}
@Override
protected void onStop() {
    // TODO Auto-generated method stub
    unregisterReceiver(myReceiver);

    super.onStop();
}
@Override
protected void onResume() {
    // TODO Auto-generated method stub

    super.onResume();
}}

Answer 1

使用unbindService() onStop()课程中的<{strong> MyService取消绑定服务（您的 Service），

和然后在stopService课程中致电 Service（您的 Activity）

我不怎么停止我的服务
