调用方法：

?????? CellInfoManager cellManager = new CellInfoManager(this);

????????????? WifiInfoManager wifiManager = new WifiInfoManager(this);

????????????? CellLocationManager locationManager = new CellLocationManager(this, cellManager, wifiManager) {

???????????????????? @Override

???????????????????? public void onLocationChanged() {

??????????????????????????? txtAutoNaviInfo.setText(this.latitude() + "-" + this.longitude());

??????????????????????????? this.stop();

???????????????????? }

????????????? };

????????????? locationManager.start();

如果还想同时使用GPS定位，其实也很简单，可以和FourSquare提供的BestLocationListener结合起来,将上面那段代码添加到BestLocationListener的register方法里：

public void register(LocationManager locationManager, boolean gps, Context context) {

??????? if (DEBUG) Log.d(TAG, "Registering this location listener: " + this.toString());

??????? long updateMinTime = SLOW_LOCATION_UPDATE_MIN_TIME;

??????? long updateMinDistance = SLOW_LOCATION_UPDATE_MIN_DISTANCE;

??????? if (gps) {

??????????? updateMinTime = LOCATION_UPDATE_MIN_TIME;

??????????? updateMinDistance = LOCATION_UPDATE_MIN_DISTANCE;

??????? }

??????? List<String> providers = locationManager.getProviders(true);

??????? int providersCount = providers.size();

??????? if (!locationManager.isProviderEnabled(LocationManager.GPS_PROVIDER) && !locationManager.isProviderEnabled(LocationManager.NETWORK_PROVIDER)){

?????????????? setChanged();

?????????????? notifyObservers(null);

??????? }

??????? for (int i = 0; i < providersCount; i++) {

??????????? String providerName = providers.get(i);

??????????? if (locationManager.isProviderEnabled(providerName)) {

??????????????? updateLocation(locationManager.getLastKnownLocation(providerName));

??????????? }

??????????? // Only register with GPS if we've explicitly allowed it.

??????????? if (gps || !LocationManager.GPS_PROVIDER.equals(providerName)) {

??????????????? locationManager.requestLocationUpdates(providerName, updateMinTime,

??????????????????????? updateMinDistance, this);

??????????? }

??????? }

??????? if(cellLocationManager == null) {

?????????????? CellInfoManager cellManager = new CellInfoManager(context);

???????????????? WifiInfoManager wifiManager = new WifiInfoManager(context);

???????????????? cellLocationManager = new CellLocationManager(context, cellManager, wifiManager) {

??????????????????????? @Override

??????????????????????? public void onLocationChanged() {

?????????????????????????????? if ((latitude() == 0.0D) || (longitude() == 0.0D)) return;

?????????????????????????????? Location result = new Location("CellLocationManager");

?????????????????????????????? result.setLatitude(latitude());

?????????????????????????????? result.setLongitude(longitude());

?????????????????????????????? result.setAccuracy(accuracy());

?????????????????????????????? onBestLocationChanged(result);

?????????????????????????????? this.stop();

??????????????????????? }

???????????????? };

??????? }

??????? //cellLocationManager.stop();

??????? cellLocationManager.start();

//??????? LocationController controller = LocationController.requestLocationUpdates("", updateMinTime,updateMinDistance, this, context);

//??????? controller.requestCurrentLocation();

??? }
