Hi! im tryng do make a zoom to some area in a Map (native)  like the MapComponent's   zoomTo(BoundingBox) use to do.

i was tryng to implemented by myself coding -but without- good results and i cant do it on the native way that i think tha its the best.

considering that that functionality was originally in the mapComponent, its possible to the team plans to implement it in the MapContainer?

also, if somebody have solve that problem , please share the code.

My CN1 code is:

        Coord centro = getCenterCoord(parBoundingBox);
        mapa.setCameraPosition(centro);
        int currentZoom = 1;
        mapa.zoom(centro, currentZoom);
        while (mapa.getBoundingBox().contains(parBoundingBox.getNorthEast()) == true && mapa.getBoundingBox().contains(parBoundingBox.getSouthWest()) == true)
        {
       currentZoom++;    
            mapa.zoom(centro, currentZoom);
        }
        currentZoom--;    
        mapa.zoom(centro, currentZoom);


If you are experiencing an issue please mention the full platform your issue applies to:

That strategy looks like it should work.  What results are you getting?

Steve: actually, didnt work on android. I was reading that the right way is to use the panToBounds() procedure in maps api.

Saldy, i have not the advanced knowledge to do it in native interface.

Can you help me?

You can file an RFE for this feature, but I don't know when I'd get around to implementing it.

The problem with your code is zoomTo() is asynchronous. After a zoomTo call, you need to wait for the map to finish zooming before you check the bounds again.  Here is a code snippet I pulled from some scratch code of mine that does roughly what you want.


It probably isn't as smooth as using the native methods directly, but it works.
