At least you can put your MapView into a RelativeLayout and add two Buttons with "+" and "-" (you can also show images within the buttons if you want). Using a RelativeLayout it is possible to show the buttons on top of the MapView, so you have the same look-and-feel as for Google Maps zoom controls. Set an OnClickListener for the buttons and perform a
mapView.zoomin()
respectively
mapView.zoomout()
.
@ESRI_DEV2011 I don't have any zoom controls in the Geometry Editing sample ... I think you mixed it up with the magnifying glass!
