I've a problem with ItemizedOverlay in a mapView.
I had folow the tuto HelloMapView in the android developpers website
and i can't display the itemized overlay in the bottom of the tuto.
I show you my code:
mapview java:
import java.util.List;
import android.content.Intent;
import android.graphics.drawable.Drawable;
import android.os.Bundle;
import android.view.Menu;
import android.view.MenuInflater;
import android.view.MenuItem;
import android.widget.LinearLayout;
import android.widget.ZoomControls;
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;
public class Map extends MapActivity {
List<Overlay> mapOverlays;
Drawable drawable;
ItemizedOverlay itemizedOverlay;
LinearLayout linearLayout;
MapView mapView;
ZoomControls mZoom;
@Override
public void onCreate(Bundle savedInstanceState) {
GeoPoint point = new GeoPoint(19240000,-99120000);
OverlayItem overlayitem = new OverlayItem(point, "", "");
itemizedOverlay.addOverlay(overlayitem);
mapOverlays.add(itemizedOverlay);
mapOverlays = mapView.getOverlays();
drawable = this.getResources().getDrawable
(R.drawable.androidmarker);
itemizedOverlay = new ItemizedOverlay(drawable);
super.onCreate(savedInstanceState);
setContentView(R.layout.map);
linearLayout = (LinearLayout) findViewById(R.id.zoomview);
mapView = (MapView) findViewById(R.id.mapview);
mapView.setBuiltInZoomControls(true);
mapView.setSatellite(true);
}
protected boolean isRouteDisplayed() {
return false;
}
}
ItemizedOverlay Java:
import android.graphics.drawable.Drawable;
import java.util.ArrayList;
import com.google.android.maps.OverlayItem;
public class ItemizedOverlay extends
com.google.android.maps.ItemizedOverlay {
private ArrayList<OverlayItem> mOverlays = new ArrayList<OverlayItem>
();
public ItemizedOverlay(Drawable defaultMarker) {
super(boundCenterBottom(defaultMarker));
}
@Override
protected OverlayItem createItem(int i) {
return mOverlays.get(i);
}
@Override
public int size() {
return mOverlays.size();
}
public void addOverlay(OverlayItem overlay) {
mOverlays.add(overlay);
populate();
}
}
map XML:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/
android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<com.google.android.maps.MapView
android:id="@+id/mapview"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:clickable="true"
android:apiKey="0GWRUwsy0_POHxdWofVfhZeFLwtgkcn7ouMfwcg"/>
<LinearLayout
android:id="@+id/zoomview"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignBottom="@id/mapview"
android:layout_centerHorizontal="true"/>
</LinearLayout>
If anyone see any error in this code ??? (I think the mistake is in
the itemizedOverlay java class but i can't find it with the debug
mode)
Thanks
Sweet
