Google map in Android, display in dimensioni ridotte mapview

Question

Desidero visualizzare la posizione nella vista mappa & dimensione della mappa deve essere 200X200. Ho provato a caricare la mappa in mapview ma non viene visualizzata correttamente dopo aver toccato il puntatore di direzione da 2 a 3 volte la sua visualizzazione della mappa corretta ma non in movimento.

Ma quando uso formato completo dello schermo per la visualizzazione mappa senza modificare il codice sta caricando correctly.How can i visualizzare stesso iin vista piccola?

mappa code-

static GoogleMap map; 
private MapView mapView; 
MapsInitializer.initialize(getApplicationContext()); 

     switch (GooglePlayServicesUtil.isGooglePlayServicesAvailable(getApplicationContext())) 
     { 
     case ConnectionResult.SUCCESS: 
      //Toast.makeText(getActivity(), "SUCCESS", Toast.LENGTH_SHORT).show(); 
      mapView = (MapView)findViewById(R.id.map); 
      mapView.onCreate(savedInstanceState); 
      // Gets to GoogleMap from the MapView and does initialization stuff 
      if(mapView!=null) 
      { 
       map = mapView.getMap(); 
       map.getUiSettings().setMyLocationButtonEnabled(false); 
       map.setMyLocationEnabled(true); 
       CameraUpdate cameraUpdate = CameraUpdateFactory.newLatLngZoom(location, 10); 
       map.animateCamera(cameraUpdate); 
       map.setMapType(GoogleMap.MAP_TYPE_NORMAL); 
      } 
      break; 
     case ConnectionResult.SERVICE_MISSING: 
      //Toast.makeText(getActivity(), "SERVICE MISSING", Toast.LENGTH_SHORT).show(); 
      break; 
     case ConnectionResult.SERVICE_VERSION_UPDATE_REQUIRED: 
      //Toast.makeText(getActivity(), "UPDATE REQUIRED", Toast.LENGTH_SHORT).show(); 
      break; 
     default: Toast.makeText(getApplicationContext(), GooglePlayServicesUtil.isGooglePlayServicesAvailable(getApplicationContext()), Toast.LENGTH_SHORT).show(); 
     } 

     CameraPosition cameraPosition = new CameraPosition.Builder() 
     .target(location).zoom(10).bearing(0) // Sets the orientation of the camera to east 
     .tilt(70) // Sets the tilt of the camera to 30 degrees 
     .build(); // Creates a CameraPosition from the builder 
     map.setBuildingsEnabled(true); 
     map.setMyLocationEnabled(true); 
     map.setMapType(GoogleMap.MAP_TYPE_NORMAL); 
     map.animateCamera(CameraUpdateFactory.newCameraPosition(cameraPosition)); 

Solution - fatto usando frammento -

map_screen.xml

<?xml version="1.0" encoding="utf-8"?> 
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    android:layout_width="match_parent" 
    android:layout_height="match_parent" 
    android:orientation="vertical" > 

    <fragment 
     android:id="@+id/mapfragment" 
     android:layout_width="wrap_content" 
     android:layout_height="200dp" 
     android:layout_alignParentTop="true" 
     android:layout_gravity="center_horizontal" 
     class="com.google.android.gms.maps.SupportMapFragment" /> 

    <TextView 
     android:id="@+id/reg_office_title" 
     android:layout_width="fill_parent" 
     android:layout_height="wrap_content" 
     android:layout_below="@+id/mapfragment" 
     android:layout_gravity="center_horizontal" 
     android:layout_marginLeft="10dp" 
     android:layout_marginRight="10dp" 
     android:layout_marginTop="5dp" 
     android:gravity="center" 
     android:text="@string/tata_auto" 
     android:textColor="@color/tatablue" 
     android:textSize="18sp" /> 

</RelativeLayout> 

codice Java -

public class MapFragment extends Fragment { 

    private View view; 

    public GoogleMap map; 
    private Location location; 
    private LatLng mAddress1; 
    public static boolean inMap=false; 

    @Override 
    public View onCreateView(LayoutInflater inflater, ViewGroup container,Bundle savedInstanceState) { 
     // TODO Auto-generated method stub 
     view= inflater.inflate(R.layout.contact_map, container, false); 
     setMapView(); 
     return view; 
    } 

    private void setMapView(){ 
     CurrentLocation mCurrentLoc=new CurrentLocation(getActivity()); 
     location = CurrentLocation.locationManager.getLastKnownLocation(LocationManager.NETWORK_PROVIDER); 
     if (location != null) { 
      mCurrentLoc.onLocationChanged(location); 
     } else { 
      mCurrentLoc.onLocationChanged(location); 
     } 

     //class="com.google.android.gms.maps.SupportMapFragment" 

     map = ((SupportMapFragment)getActivity().getSupportFragmentManager().findFragmentById(R.id.mapfragment)).getMap(); 


     CameraPosition cameraPosition = new CameraPosition.Builder() 
     .target(mAddress1).zoom(8).bearing(0) // Sets the orientation of the camera to east 
     .tilt(30) // Sets the tilt of the camera to 30 degrees 
     .build(); // Creates a CameraPosition from the builder 
     map.setBuildingsEnabled(true); 
     map.setMyLocationEnabled(true); 
     map.setMapType(GoogleMap.MAP_TYPE_NORMAL); 
     map.animateCamera(CameraUpdateFactory.newCameraPosition(cameraPosition)); 


    } 
} 

mAddress1 è la latitudine e la longitudine della vostra posizione.

Ho testato il codice qui sotto e non ci sono problemi con la mappa per la dimensione 200dp x 200dp

Disposizione:

<?xml version="1.0" encoding="utf-8"?> 
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    android:layout_width="match_parent" 
    android:layout_height="match_parent" 
    android:background="#FFFFFF" 
    android:orientation="vertical"> 

    <fragment 
     android:id="@+id/map" 
     class="com.google.android.gms.maps.SupportMapFragment" 
     android:layout_width="200dp" 
     android:layout_height="200dp" /> 

</LinearLayout> 

Frammento:

public class LocationFragment extends Fragment 
{ 
    GoogleMap googleMap; 

    @Override 
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) 
    { 
     View v = inflater.inflate(R.layout.fragment_location, container, false); 

     googleMap = ((SupportMapFragment) getFragmentManager().findFragmentById(R.id.map)).getMap(); 

     MapsInitializer.initialize(getActivity().getApplicationContext()); 

     googleMap.addMarker(new MarkerOptions() 
       .position(new LatLng(38.7222524, -9.139336599999979)) 
       .title("MyLocation") 
       .icon(BitmapDescriptorFactory 
         .fromResource(R.drawable.ic_mobileedge_navpoint))); 

     // Move the camera instantly with a zoom of 15. 
     googleMap.moveCamera(CameraUpdateFactory.newLatLngZoom(new LatLng(38.7222524, -9.139336599999979), 15)); 

     // Zoom in, animating the camera. 
     googleMap.animateCamera(CameraUpdateFactory.zoomTo(12), 1000, null); 

     return v; 
    } 
} 

Answer 2

vedo che tu sei usando MapView invece di MapFragment. In Google Maps V2, la vecchia classe MapView com.google.android.maps.MapView è obsoleta. Quindi assicuratevi di utilizzare il MapView corretto sia nel codice Java e il layout XML che dovrebbe essere

import com.google.android.gms.maps.MapView; 

e

<com.google.android.gms.maps.MapView 
    android:id="@+id/map_view" 
    android:layout_width="your_width" 
    android:layout_height="your_height" /> 

assicurarsi di aver fatto tutte le modifiche necessarie nella AndroidManifest.xml Inoltre, che comprende definendo l'API_KEY per Maps V2 as described here.

Oltre a questo, c'è una cosa importante che devi fare se si utilizza MapView al posto di un MapFragment, è necessario chiamare le funzioni override del MapView esplicitamente all'interno delle corrispondenti override di residenti Attività proprio come,

public class YourMapActivity extends Activity { 

    MapView mMapView; 
    GoogleMap mMap; 

    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 

     /* Your OnCreate with Map Initialization */ 

     mMapView = (MapView) findViewById(R.id.map_view); 
     mMapView.onCreate(Bundle.EMPTY); 

     mMap = mMapView.getMap(); 
     MapsInitializer.initialize(this); 
    } 

    @Override 
    protected void onResume() { 
     mMapView.onResume(); 
     super.onResume(); 
    } 

    @Override 
    protected void onPause() { 
     mMapView.onPause(); 
     super.onPause(); 
    } 

    @Override 
    protected void onDestroy() { 
     mMapView.onDestroy(); 
     super.onDestroy(); 
    } 

    @Override 
    public void onLowMemory() { 
     mMapView.onLowMemory(); 
     super.onLowMemory(); 
    } 
} 

Questo dovrebbe essere sufficiente per caricare un MapView di dimensioni personalizzate in Acitivity. È inoltre possibile utilizzare le seguenti funzioni per adattarlo alle proprie esigenze.

mMapView.setClickable(false); 

mMap.getUiSettings().setMyLocationButtonnabled(false); 
mMap.getUiSettings().setZoomControlsEnabled(false); 
mMap.getUiSettings().setCompassEnabled(false); 
mMap.getUiSettings().setZoomGesturesEnabled(false); 
mMap.getUiSettings().setScrollGesturesEnabled(false); 
mMap.setMyLocationEnabled(true);
