J'ai un problème avec ce code, "ne peut pas résoudre la méthode getMap (). Je ne trouve pas où est le problème, veuillez demander de l'aide avec le code, j'utilise Android Studio et je dois prendre les repères de MySQL avec Json.
googleMap = ((SupportMapFragment) getSupportFragmentManager().findFragmentById(R.id.googleMap)).getMap();`
Et voici le code complet
public class MainActivity extends FragmentActivity {

la méthode getMap () a été amortie, mais après la mise à jour de play-services 9.2, elle a été supprimée. Il est donc préférable d'utiliser getMapAsync (). Vous pouvez toujours utiliser getMap () uniquement si vous ne souhaitez pas mettre à jour les services de jeu à la version 9.2 pour votre application.
Pour utiliser getMapAsync (), implémentez l'interface OnMapReadyCallback sur votre activité ou votre fragment:
public class Fragment_Map extends Android.support.v4.app.Fragment
implements OnMapReadyCallback { }
Ensuite, lors de l’initialisation de la carte, utilisez getMapAsync () au lieu de getMap ():
private void initializeMap() {
if (mMap == null) {
SupportMapFragment mapFrag = (SupportMapFragment) getChildFragmentManager().findFragmentById(R.id.fragment_map);
mapFrag.getMapAsync(this);
}
}
@Override
public void onMapReady(GoogleMap googleMap) {
mMap = googleMap;
setUpMap();
}
getMap
est obsolète, utilisez getMapAsync
ci-dessous.
alors changez ceci en googleMap = ((SupportMapFragment) getSupportFragmentManager().findFragmentById(R.id.googleMap)).getMap();
en googleMap = ((SupportMapFragment) getSupportFragmentManager().findFragmentById(R.id.googleMap)).getMapAsync();
Mettre à jour :
Utilisez cette façon,
package your.app.name;
import Android.app.Activity;
import Android.os.Bundle;
import Android.view.Menu;
import Android.view.MenuItem;
import com.google.Android.gms.maps.GoogleMap;
import com.google.Android.gms.maps.MapFragment;
import com.google.Android.gms.maps.OnMapReadyCallback;
import com.google.Android.gms.maps.model.LatLng;
import com.google.Android.gms.maps.model.MarkerOptions;
public class MainActivity extends Activity implements OnMapReadyCallback {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
MapFragment mapFragment = (MapFragment) getFragmentManager()
.findFragmentById(R.id.map);
mapFragment.getMapAsync(this);
}
@Override
public void onMapReady(GoogleMap map) {
map.addMarker(new MarkerOptions()
.position(new LatLng(0, 0))
.title("Marker"));
}
//onCreateOptionsMenu: no changes
//onOptionsItemSelected: no changes
}
J'ai un problème avec load Json maintenant, "getMap", il est obsolète et Google a dit que je devais utiliser getMap (). Comment puis-je résoudre le problème?
cela vous avez le code
try {
JSONArray innerJsonArray = json_array.getJSONArray(0);
JSONObject json = innerJsonArray.getJSONObject(0);
MapFragment mapFrag = (MapFragment) getFragmentManager().findFragmentById(R.id.map);
GeoJsonLayer layer = new GeoJsonLayer(mapFrag.getMap() , json);
layer.addLayerToMap();
} catch (JSONException e) {
e.printStackTrace();
}

cela fonctionnera parfaitement. Merci.
