Android: Skobbler, How To Limit Map View In An Area?

I'm new not only on Skobbler but also for Map. At this time, i'm trying to create a mapp app that show only an area. And, what i want are: User can't move out of that area. Don'

Solution 1:

Currently the SDK does not support limiting map operations to a bounding box.

As a workaround, whenever the map region that is visible on the screen changes (as a result of panning, zooming or rotation) and it goes outside the defined bounding box the map will switch back to the last visible region that was inside that bounding box:

publicclassMapActivityextendsActivityimplementsSKMapSurfaceListener, ... { 

... 
// the box inside which map operations are allowed privateSKBoundingBoxbox=newSKBoundingBox(47.087426, 8.257230, 46.874277, 8.637632); 

// last region that was visible on the screen and was inside the box privateSKCoordinateRegionlastValidRegion=null; 

... 

@OverridepublicvoidonSurfaceCreated(SKMapViewHolder mapHolder) { 
... 
// position the map somewhere inside your box 
mapView.centerMapOnPosition(newSKCoordinate(8.304354, 47.050253)); 
} 

... 

// checks if a given region is inside the bounding box privatebooleanisInBoundingBox(SKCoordinateRegion newRegion) { 
        SKBoundingBoxnewBoundingBox= mapView.getBoundingBoxForRegion(newRegion); 
        if (newBoundingBox.getTopLeftLatitude() > box.getTopLeftLatitude() || newBoundingBox.getBottomRightLatitude() < box.getBottomRightLatitude() || 
                newBoundingBox.getTopLeftLongitude() < box.getTopLeftLongitude() || newBoundingBox.getBottomRightLongitude() > box.getBottomRightLongitude()) { 
            returnfalse; 
        } 
        returntrue; 
    } 

@OverridepublicvoidonMapRegionChanged(SKCoordinateRegion mapRegion) { 
        booleaninBoundingBox= isInBoundingBox(mapRegion); 
        if (inBoundingBox) { 
// if mapRegion is valid save it if (lastValidRegion == null) { 
                lastValidRegion = newSKCoordinateRegion(mapRegion.getCenter(), mapRegion.getZoomLevel()); 
            } else { 
                lastValidRegion.setCenter(mapRegion.getCenter()); 
                lastValidRegion.setZoomLevel(mapRegion.getZoomLevel()); 
            } 
        } else { 
// if mapRegion is invalid reposition the map inside the bounding box if (lastValidRegion != null) { 
                mapView.changeMapVisibleRegion(lastValidRegion, false); 
            } 
        } 
    } 

} 

Also, if needed, limits can also be applied to zoom levels using the SKMapSettings.setZoomLimits(...) method.
