Question

我有一个定期为服务器发送数据的服务，经度和纬度来自要发送的数据。问题是异步任务总是在registerLocationUpdates（）结束之前开始执行，请帮我解决它，我唯一想要的是保证在寄存器位置更新结束之前不会执行PostQos任务。

public class QosTestsService extends Service {

private Handler handler;
SharedPreferences mshared;
protected LocationManager locationManager;
protected LocationListener locationListener;
double longitude = 0.0, latitude = 0.0;
String provider;
boolean waitingForLocationUpdate = true;

private boolean firstTime = true, running = true;
@Override
public IBinder onBind(Intent intent) {
    // TODO Auto-generated method stub
    return null;
}

@Override
public void onCreate() {
    Toast.makeText(this, " MyService Created ", Toast.LENGTH_LONG).show();

}

@Override
public int onStartCommand(Intent intent, int flags, int startId) {
    Toast.makeText(this, " MyService Started", Toast.LENGTH_LONG).show();

    int delay = 5000; //milliseconds
    mshared = PreferenceManager.getDefaultSharedPreferences(getApplicationContext());


    handler = new Handler();
    handler.postDelayed(new Runnable() {
        public void run() {
            handler.postDelayed(this, MyApplication.routineSchedule.getFrequency() * 60 * 1000);
            if (MyApplication.routineSchedule.getEnabled().equals("true")){

                registerLocationUpdates(); 
                new PostQosTest(getApplicationContext(), true).execute();
            } 
        }
    }, delay);
    return START_STICKY;
}

private void registerLocationUpdates() {
    Criteria criteria = new Criteria();
    criteria.setAccuracy(Criteria.ACCURACY_LOW);
    criteria.setPowerRequirement(Criteria.POWER_LOW);
    criteria.setAltitudeRequired(false);
    criteria.setBearingRequired(false);

    locationManager = (LocationManager) this
            .getSystemService(LOCATION_SERVICE);

    provider = locationManager.getBestProvider(criteria, true);

    // Cant get a hold of provider
    if (provider == null) {
        return;
    }

    locationListener = new MyLocationListener();


    if (ActivityCompat.checkSelfPermission(this, android.Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED && ActivityCompat.checkSelfPermission(this, android.Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED) {

        return;
    }
    locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, 0,
            0, locationListener);
    locationManager.requestLocationUpdates(
            LocationManager.NETWORK_PROVIDER, 0, 0, locationListener);
    // connect to the GPS location service
    Location oldLocation = locationManager.getLastKnownLocation(provider);

    if (oldLocation != null) {
        waitingForLocationUpdate = false;
    }
}

private class MyLocationListener implements LocationListener {

    public void onLocationChanged(Location location) {
        latitude = location.getLatitude();
        longitude = location.getLongitude();
        Log.d("hello im here", "the value are " + latitude + " "
                + longitude);// , msg)
        // Log.v(TAG, "IN ON LOCATION CHANGE");

        if (waitingForLocationUpdate) {
            // getNearbyStores();
            waitingForLocationUpdate = false;
        }

        if (ActivityCompat.checkSelfPermission(getApplicationContext(), android.Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED && ActivityCompat.checkSelfPermission(getApplicationContext(), android.Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED) {

            return;
        }
        locationManager.removeUpdates(this);
    }

    public void onStatusChanged(String s, int i, Bundle bundle) {
        // Log.v(TAG, "Status changed: " + s);
    }

    public void onProviderEnabled(String s) {
        // Log.e(TAG, "PROVIDER DISABLED: " + s);
    }

    public void onProviderDisabled(String s) {
        // Log.e(TAG, "PROVIDER DISABLED: " + s);
    }
}

Answer 1

解决了，我只是将执行代码移动到了on location changed函数的最后一行。

等待位置更改结束
