Google Maps V2 - Android - Get current zoom level

Question

How to get the current zoom level as an integer in GoogleMap. I need to take this code from GMaps v1.1:

MapView mGoogleMapView; int zoomLevel = mGoogleMapView.getZoomLevel(); 

I know the getMinZoomLevel () and getMaxZoomLevel () methods, however I cannot find anything in the Android GMap V2 documentation that will give the current zoom level. Does anyone have pointers on how to do this?

Any help would be appreciated.

Answer 1

 GoogleMap map; 

....

 float zoom = map.getCameraPosition().zoom; 

Answer 2

I think OnCameraChangeListener will do the trick.

 map.setOnCameraChangeListener(new OnCameraChangeListener() { private float currentZoom = -1; @Override public void onCameraChange(CameraPosition position) { if (position.zoom != currentZoom){ currentZoom = position.zoom; // here you get zoom level } } }); 

Update:

From Google Play 9.4.0, OnCameraChangeListener is deprecated and it will no longer work anytime soon. Subsequently, they are replaced by OnCameraMoveStarted Listener , OnCameraMoveListener , OnCameraMoveCancel edListener and OnCameraIdleListener .

Therefore, we can use OnCameraIdleListener to get the current zoom level of the camera.

Code example:

 map.setOnCameraIdleListener(new GoogleMap.OnCameraIdleListener() { @Override public void onCameraIdle() { int zoomLevel = map.getCameraPosition().zoom; //use zoomLevel value.. } }); 

Answer 3

Call getCameraPosition() on GoogleMap and read the zoom field from the resulting CameraPosition object .
