I cannot find a notification method when users click this button, which appears when setMyLocationEnabled is setMyLocationEnabled .
setMyLocationEnabled
Google Maps Android API v2 does not currently support this event.
See the code in the My Tracks app for a workaround
https://code.google.com/p/mytracks/source/browse/MyTracks/src/com/google/android/apps/mytracks/fragments/MyTracksMapFragment.java
/* * My Tracks needs to handle the onClick event when the my location button * is clicked. Currently, the API doesn't allow handling onClick event, * thus hiding the default my location button and providing our own. */
