在适用于Android的Google API 10中显示我当前的位置

Question

I'm having problem with showing my current location in this code. Can you please tell me how to add code that will zoom and show my current location.

public class MapaActivity extends MapActivity
{

 @Override
 public void onCreate(Bundle savedInstanceState)
 {

 super.onCreate(savedInstanceState);
 setContentView(R.layout.mapa);

 MapView mapView = (MapView) findViewById(R.id.mapview);
 mapView.setBuiltInZoomControls(true);

 List<Overlay> mapOverlays = mapView.getOverlays();
 Drawable drawable = this.getResources().getDrawable(R.drawable.icon);
 HelloItemizedOverlay itemizedoverlay = new HelloItemizedOverlay(drawable,this);

 GeoPoint point = new GeoPoint(44900101,14839100);
 OverlayItem overlayitem = new OverlayItem(point, "Pin","Test pin");

 itemizedoverlay.addOverlay(overlayitem);



 mapOverlays.add(itemizedoverlay);

Answer 1

For your GeoPoint you can use:

LocationManager locationManager;
        locationManager=(LocationManager) getSystemService(LOCATION_SERVICE);
        Location location=locationManager.getLastKnownLocation(LocationManager.NETWORK_PROVIDER);
        GeoPoint point=new GeoPoint((int)(location.getLatitude()*1E6),(int)(location.getLongitude()*1E6));

And at the end add:

 mapView.getController().animateTo(point);

In the Manifest file add permission:

<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"/>
<uses-permission android:name="android.permission.INTERNET"/>
