i am trying to scale pictures in a Android map itemizedOverlay, i got it working to the point where i can see 10 pictures, i got zoomControle but nothing else really,
this is the MapItems class that extends ItemizedOverlay, optimizations is welcome
import java.util.ArrayList;
import android.content.Context;
import android.graphics.drawable.Drawable;
import android.util.Log;
import com.google.android.maps.ItemizedOverlay;
import com.google.android.maps.MapView;
import com.google.android.maps.OverlayItem;
public class MapItems extends ItemizedOverlay
{
private ArrayList<OverlayItem> mOverlays = new ArrayList<OverlayItem>();
Context mContext;
public MapItems(Drawable defaultMarker)
{
super(boundCenterBottom(defaultMarker));
}
@Override
public void draw(android.graphics.Canvas canvas,MapView mapView,boolean shadow)
{
/*
Log.d("MapAc", String.valueOf(mapView.getZoomLevel()));
if(mapView.getZoomLevel() > 20)
{
Log.d("MapAc", "scaling up");
canvas.scale(1.2f, 1.2f);
}
*/
super.draw(canvas,mapView,false);
}
public MapItems(Context context)
{
super(boundCenterBottom(context.getResources().getDrawable(R.drawable.app_icon_clean)));
mContext = context;
}
public void addOverlay(OverlayItem overlay)
{
mOverlays.add(overlay);
populate();
}
public void clearOverlay()
{
mOverlays.clear();
}
@Override
protected OverlayItem createItem(int i)
{
return mOverlays.get(i);
}
@Override
public int size()
{
return mOverlays.size();
}
@Override
protected boolean onTap(int index)
{
/* ToDo
OverlayItem item = mOverlays.get(index);
AlertDialog.Builder dialog = new AlertDialog.Builder(mContext);
dialog.setTitle(item.getTitle());
dialog.setMessage(item.getSnippet());
dialog.show();
*/
return true;
}
}
i have been trying to scale in the draw method, using canvas.Scale, however this seems to redraw the canvas in another location, together with the old canvas"in its original size", i am not sure if i am approaching this problem from the right angle, or if it is simply a matter of clearing the screen, i have been using a few days to figure this out, so a method to scale my pictures correct when zooming is VERY appreciated,
