Marcador predeterminado para android google MAPVIEW?

Si utiliza Eclipse como IDE, puede agregar un .png, por ejemplo, a sus directorios / drawable-hdpi, / drawable-ldpi, / drawable-mdpi. A continuación, puede colocar y obtener una lista de referencias a sus superposiciones algo así:

package com.practice.mapper; import java.util.ArrayList; import android.graphics.drawable.Drawable; import com.google.android.maps.ItemizedOverlay; import com.google.android.maps.OverlayItem; public class Itemization extends ItemizedOverlay<OverlayItem> { private ArrayList<OverlayItem> mOverlays = new ArrayList<OverlayItem>(); public Itemization(Drawable defaultMarker) { super(boundCenterBottom(defaultMarker)); // super(defaultMarker); } @Override protected OverlayItem createItem(int i) { return mOverlays.get(i); } public void addOverlay(OverlayItem overlay) { mOverlays.add(overlay); populate(); } @Override public int size() { return mOverlays.size(); } } package com.practice.mapper; import java.util.List; import com.google.android.maps.GeoPoint; import com.google.android.maps.MapActivity; import com.google.android.maps.MapView; import com.google.android.maps.Overlay; import com.google.android.maps.OverlayItem; import android.content.Context; import android.graphics.drawable.Drawable; import android.location.Location; import android.location.LocationListener; import android.location.LocationManager; import android.location.LocationProvider; import android.os.Bundle; import android.util.Log; import android.view.View; import android.view.View.OnClickListener; import android.widget.Button; import android.widget.LinearLayout; import android.widget.ZoomControls; public class Mapper extends MapActivity implements LocationListener { Location presentLocation; ZoomControls z; LinearLayout linearLayout; MapView mapView; List<Overlay> mapOverlays; Drawable drawable; Itemization itemizedOverlay; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); mapView = (MapView) findViewById(R.id.mapview); mapView.setBuiltInZoomControls(true); mapOverlays = mapView.getOverlays(); drawable = this.getResources().getDrawable(R.drawable.androidmarker); itemizedOverlay = new Itemization(drawable); GeoPoint point = new GeoPoint(19240000, -99120000); OverlayItem overlayitem = new OverlayItem(point, "", ""); itemizedOverlay.addOverlay(overlayitem); GeoPoint point2 = new GeoPoint(35410000, 139460000); OverlayItem overlayitem2 = new OverlayItem(point2, "", ""); itemizedOverlay.addOverlay(overlayitem2); mapOverlays.add(itemizedOverlay); } public void btnUpdateClicked(View v) { LocationManager lm = (LocationManager)getSystemService(Context.LOCATION_SERVICE); LocationProvider p = lm.getProvider(LocationManager.GPS_PROVIDER); lm.requestLocationUpdates(LocationManager.GPS_PROVIDER, 20000, 1, this); List<String> enabledProv = lm.getProviders(true); Location l1 = lm.getLastKnownLocation(LocationManager.GPS_PROVIDER); Location l2 = lm.getLastKnownLocation(LocationManager.NETWORK_PROVIDER); Location l3 = lm.getLastKnownLocation(LocationManager.PASSIVE_PROVIDER); Button b = new Button(this.getApplicationContext()); b.setOnClickListener(new OnClickListener(){ public void onClick(View v) { }}); lm.toString(); } @Override protected boolean isRouteDisplayed() { return false; } public void onLocationChanged(Location location) { presentLocation = location; Log.d("TEST", "New location received"); } public void onProviderDisabled(String provider) { } public void onProviderEnabled(String provider) { } public void onStatusChanged(String provider, int status, Bundle extras) { } } 

Tengo la mayor parte de este código de un tutorial ya no puedo encontrar el enlace a. Las superposiciones son bastante simples de manipular. Espero que esto ayude.

Si está utilizando Google Maps Android API v2, puede utilizar el siguiente método.

 mapView.getMap().addMarker(new MarkerOptions() .position(new LatLng(10, 10)) .title("Hello world"));
