Don't snap to marker after click in android map v2

Question

Currently Android Map v2 snaps to marker location after click. I want to disable this behavior but see no options to do it.

Does anybody know how to fix that?

Based on what I read from the Markers - Google Maps Android API (https://developers.google.com/maps/documentation/android/marker#marker_click_events)

Marker click events

You can use an OnMarkerClickListener to listen for click events on the marker. To set this listener on the map, call GoogleMap.setOnMarkerClickListener(OnMarkerClickListener). When a user clicks on a marker, onMarkerClick(Marker) will be called and the marker will be passed through as an argument. This method returns a boolean that indicates whether you have consumed the event (i.e., you want to suppress the default behavior). If it returns false, then the default behavior will occur in addition to your custom behavior. The default behavior for a marker click event is to show its info window (if available) and move the camera such that the marker is centered on the map.

You could likely override this method and have it only open the marker and return true to consume the event.

// Since we are consuming the event this is necessary to // manage closing opened markers before opening new ones Marker lastOpened = null;  mMap.setOnMarkerClickListener(new OnMarkerClickListener() {     public boolean onMarkerClick(Marker marker) {         // Check if there is an open info window         if (lastOpened != null) {             // Close the info window             lastOpened.hideInfoWindow();              // Is the marker the same marker that was already open             if (lastOpened.equals(marker)) {                 // Nullify the lastOpened object                 lastOpened = null;                 // Return so that the info window isn't opened again                 return true;             }          }          // Open the info window for the marker         marker.showInfoWindow();         // Re-assign the last opened such that we can close it later         lastOpened = marker;          // Event was handled by our code do not launch default behaviour.         return true;     } }); 

This is untested code but that may be a workable solution.

It appears we should be able to do the following, but due to this bug, it doesn't work because marker.isInfoWindowShown() always returns false:

mMap.setOnMarkerClickListener(new GoogleMap.OnMarkerClickListener() {     public boolean onMarkerClick(Marker marker) {         if (marker.isInfoWindowShown()) {             marker.hideInfoWindow();         } else {             marker.showInfoWindow();         }         return true;     } }); 

However, the following has the same effect and does work:

mMap.setOnMarkerClickListener(new GoogleMap.OnMarkerClickListener() {      Marker currentShown;      public boolean onMarkerClick(Marker marker) {         if (marker.equals(currentShown)) {             marker.hideInfoWindow();             currentShown = null;         } else {             marker.showInfoWindow();             currentShown = marker;         }         return true;     } }); 

Because only one info window is displayed at a time (as stated in the Google Maps API v2 Developer Guide), we only have to bother about hiding the info window if the marker whose info window is currently open is clicked.
