Ajouter Google Maps API V2 dans un fragment
J'essaie de montrer la carte fragmentée de l'API Google Maps V2. J'ai essayé avec SupportMapFragment, mais je ne parviens pas à obtenir le résultat attendu ..__ également, je suis débutant sur cette plateforme! Ce que je veux vraiment, c’est juste un moyen de mettre une carte à partir de l’API Google Maps V2 pour Android dans un fragment. S'il vous plaît partager vos idées et vos références.
Merci d'avance !
Voici le code,
public class YourFragment extends Fragment {
// ...
static final LatLng HAMBURG = new LatLng(53.558, 9.927);
static final LatLng KIEL = new LatLng(53.551, 9.993);
private GoogleMap map;
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View v = inflater.inflate(R.layout.yourlayout, null, false);
map = ((SupportMapFragment) getFragmentManager().findFragmentById(R.id.map))
.getMap();
Marker hamburg = map.addMarker(new MarkerOptions().position(HAMBURG)
.title("Hamburg"));
Marker kiel = map.addMarker(new MarkerOptions()
.position(KIEL)
.title("Kiel")
.snippet("Kiel is cool")
.icon(BitmapDescriptorFactory
.fromResource(R.drawable.ic_launcher)));
// Move the camera instantly to hamburg with a zoom of 15.
map.moveCamera(CameraUpdateFactory.newLatLngZoom(HAMBURG, 15));
// Zoom in, animating the camera.
map.animateCamera(CameraUpdateFactory.zoomTo(10), 2000, null);
//...
return v;
}

Mise à jour 24/10/2014 Tout cela est faux. Vous ne devriez pas avoir un fragment dans un fragment. Au lieu de cela, vous devriez étendre le SupportMapFragment. Voir cet article stackoverflow pour quelques détails: https://stackoverflow.com/a/19815266/568197
voici mon onDestroyView ()
public void onDestroyView() {
super.onDestroyView();
if (mMap != null) {
getFragmentManager()
.beginTransaction()
.remove(getFragmentManager().findFragmentById(R.id.map))
.commit();
}
}
en plus de la réponse ci-dessus, je devais également mettre les lignes suivantes à mon manifeste
<!-- inside <aplication> tag -->
<meta-data
Android:name="com.google.Android.gms.version"
Android:value="@integer/google_play_services_version" />
Et j'ai aussi changé la mise en page pour utiliser SupportMapFragment au lieu de MapFragment
<fragment
Android:id="@+id/map"
Android:layout_width="match_parent"
Android:layout_height="match_parent"
class="com.google.Android.gms.maps.SupportMapFragment" />
Utilisez SupportMapFragment au lieu de MapFragment et utilisez getActivity()
Voici un exemple de base utilisant SupportMapFragment:
public class MainActivity extends ActionBarActivity implements OnMapReadyCallback{
private SupportMapFragment map;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
map = (SupportMapFragment) getSupportFragmentManager().findFragmentById(R.id.map);
map.getMapAsync(this);//remember getMap() is deprecated!
}
@Override
public void onMapReady(GoogleMap map) {
map.moveCamera(CameraUpdateFactory.newLatLngZoom(
new LatLng(47.17, 27.5699), 16));
map.addMarker(new MarkerOptions()
.icon(BitmapDescriptorFactory.fromResource(R.drawable.ic_launcher))
.anchor(0.0f, 1.0f) // Anchors the marker on the bottom left
.position(new LatLng(47.17, 27.5699))); //Iasi, Romania
map.setMyLocationEnabled(true);
}
}
et changez la référence dans votre mise en page:
<fragment
Android:id="@+id/map"
Android:layout_width="match_parent"
Android:layout_height="match_parent"
class="com.google.Android.gms.maps.SupportMapFragment" />

Si vous utilisez Android Studio, créez Google Mapsactivity avec son fragment de carte par défaut, générez votre clé API de carte et effectuez vos opérations ......
SupportMapFragment mapFragment = (SupportMapFragment) getSupportFragmentManager (). FindFragmentById (R.id.map); MapFragment.getMapAsync (this);
et notre méthode de substitution

mMap.addMarker(new MarkerOptions().position(map).title("your title"));
mMap.animateCamera(CameraUpdateFactory.newLatLng(map));
