Comment faire pour récupérer actuel emplacement du périphérique & montrer sur la carte de fragment en fragment

Comment sur l'utilisation de la nouvellement introduite fusionné fournisseur d'emplacement
comme référencé à partir de: http://developer.android.com/training/location/retrieve-current.html

public static class XYZ extends Fragment
implements
GooglePlayServicesClient.ConnectionCallbacks,
GooglePlayServicesClient.OnConnectionFailedListener,
LocationListener {
GoogleMap map;
LatLng latlng;
private LocationRequest lr;
private LocationClient lc;
MapFragment mapFragment;
ImageView iv;
private static View view;
public XYZ() {
}
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
if (view != null) {
ViewGroup parent = (ViewGroup) view.getParent();
if (parent != null)
parent.removeView(view);
}
try {
view = inflater.inflate(R.layout.XYZ, container,
false);
mapFragment = ((MapFragment) this.getActivity()
.getFragmentManager().findFragmentById(R.id.map));
iv = (ImageView) view.findViewById(R.id.iv);
map = mapFragment.getMap();
map.getUiSettings().setAllGesturesEnabled(false);
map.getUiSettings().setMyLocationButtonEnabled(false);
map.setMyLocationEnabled(true);
map.getUiSettings().setZoomControlsEnabled(false);
MapsInitializer.initialize(this.getActivity());
} catch (GooglePlayServicesNotAvailableException e) {
Toast.makeText(getActivity(), "Google Play Services missing !",
Toast.LENGTH_LONG).show();
} catch (InflateException e) {
Toast.makeText(getActivity(), "Problems inflating the view !",
Toast.LENGTH_LONG).show();
} catch (NullPointerException e) {
Toast.makeText(getActivity(), "Google Play Services missing !",
Toast.LENGTH_LONG).show();
}
return view;
}
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
lr = LocationRequest.create();
lr.setPriority(LocationRequest.PRIORITY_HIGH_ACCURACY);
lc = new LocationClient(this.getActivity().getApplicationContext(),
this, this);
lc.connect();
}
@Override
public void onLocationChanged(Location l2) {
CameraUpdate cameraUpdate = CameraUpdateFactory.newLatLngZoom(
new LatLng(l2.getLatitude(), l2.getLongitude()), 15);
map.animateCamera(cameraUpdate);
}
@Override
public void onConnectionFailed(ConnectionResult arg0) {
}
@Override
public void onConnected(Bundle connectionHint) {
lc.requestLocationUpdates(lr, this);
}
@Override
public void onDisconnected() {
}
}

Avec le XML:

      <?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_marginBottom="4dp"
android:layout_weight="1" >
<fragment
android:id="@+id/map"
android:name="com.google.android.gms.maps.MapFragment"
android:layout_width="match_parent"
android:layout_height="match_parent"
/>
<ImageView
android:id="@+id/iv"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="@android:color/transparent" />
</RelativeLayout>

Vous pouvez obtenir une carte vierge si vous n'avez pas à toutes les exigences, https://developers.google.com/maps/documentation/android/start

1. De Jouer les services de votre projet en suivant ce post
   https://blog-emildesign.rhcloud.com/?p=435

2. Puis obtenir une clé api: https://blog-emildesign.rhcloud.com/?p=403

3. Ajouter des autorisations à vous manifester,

      <uses-permission android:name="your.application.package.permission.MAPS_RECEIVE"/>
   <uses-permission android:name="android.permission.INTERNET" />
   <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
   <uses-permission    android:name="com.google.android.providers.gsf.permission.READ_GSERVICES"/>
   <uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
   <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />

4. De test de la carte de l'application, vous devez avoir un périphérique réel, si non, puis appuyez sur play services de l'émulateur via adb, lire cet article pour savoir comment installer play via adb https://stackoverflow.com/a/13869332/826657

5. Après toutes les étapes ci-dessus, le nettoyage de votre projet, de désinstaller la précédente .apk à partir de l'émulateur, et exécuter le projet.

Voici le Lien qui explique toutes les choses que vous avez besoin

https://developers.google.com/maps/documentation/android/map

Pour définir l'emplacement sur la Carte, vous devez utiliser au-dessous de la classe

LatLong objLatLng=new LatLong(lat,longi);
yourMapObject.moveCamera(CameraUpdateFactory.newLatLngZoom(objLatLng, 20));
yourMapObject.animateCamera(CameraUpdateFactory.zoomTo(18), 2000, null);

Espère que cela va vous aider.

Use LocationListener:
GPSTracker objGPSTracker = new GPSTracker(mContext);
objGPSTracker.stopUsingGPS();
objGPSTracker.getLocation();

C'est la classe pour GPSTracker

public class GPSTracker extends Service implements LocationListener {
private final Context mContext;
//flag for GPS status
boolean isGPSEnabled = false;
//flag for network status
boolean isNetworkEnabled = false;
//flag for GPS status
boolean canGetLocation = false;
//
Location location; //location
double latitude; //latitude
double longitude; //longitude
//The minimum distance to change Updates in meters
private static final long MIN_DISTANCE_CHANGE_FOR_UPDATES = 50; //10 meters
//The minimum time between updates in milliseconds
private static final long MIN_TIME_BW_UPDATES = 1000 * 60 * 1; //1 minute
//Declaring a Location Manager
protected LocationManager locationManager;
public GPSTracker(Context context) {
this.mContext = context;
//getLocation();
}
public Location getLocation() {
try {
locationManager = (LocationManager) mContext.getSystemService(LOCATION_SERVICE);
//getting GPS status
isGPSEnabled = locationManager.isProviderEnabled(LocationManager.GPS_PROVIDER);
//getting network status
isNetworkEnabled = locationManager.isProviderEnabled(LocationManager.NETWORK_PROVIDER);
if (!isGPSEnabled && !isNetworkEnabled) {
//no network provider is enabled
} else {
this.canGetLocation = true;
if (isNetworkEnabled) {
locationManager.requestLocationUpdates(
LocationManager.NETWORK_PROVIDER,
MIN_TIME_BW_UPDATES,

Log.d("Network", "Network");
if (locationManager != null) {

//if GPS Enabled get lat/long using GPS Services
