We\'re building an application which is using the google maps api for android.
I have my MapController and MapView, and I enable the built-in zoom controls using:
The android API suggests you use ZoomControls which has a setOnZoomInClickListener()
To add these zoom controls you would:
ZoomControls mZoom = (ZoomControls) mapView.getZoomControls();
And then add mZoom to your layout.
