Avoid using Activity implements OnMarkerClickListener  use a local OnMarkerClickListener     Not a good idea class MapActivity extends Activity implements OnMarkerClickListener       You will need a map to lookup the original data model linked to the marker  private Map lt Marker  Map lt String  Object gt  gt  markers   new HashMap lt  gt       You will need a data model  private Map lt String  Object gt  dataModel   new HashMap lt  gt       Put some data in the data model  dataModel put  title    My Spot    dataModel put  snipet    This is my spot     dataModel put  latitude   20 0f   dataModel put  longitude   100 0f     When creating a new marker using a data model add both to the maker map  Marker marker   googleMap addMarker markerOptions   markers put marker  dataModel     For on click marker event  use a local OnMarkerClickListener    Override public void onMapReady GoogleMap googleMap           grab for laters     this googleMap   googleMap       googleMap setOnMarkerClickListener new GoogleMap OnMarkerClickListener              Override         public boolean onMarkerClick Marker marker                Map dataModel    Map markers get marker               String title    String dataModel get  title                markerOnClick title                return false                         mapView onResume         showMarkers         ZoomAsync zoomAsync   new ZoomAsync        zoomAsync execute        For displaying the info window retrieve the original data model from the marker map    Override public void onMapReady GoogleMap googleMap        this googleMap   googleMap      googleMap setOnInfoWindowClickListener new GoogleMap OnInfoWindowClickListener              Override         public void onInfoWindowClick Marker marker                Map dataModel    Map markers get marker               String title    String dataModel get  title                 infoWindowOnClick title

Another Solution   you get the marker by its title   public class MarkerDemoActivity extends android support v4 app FragmentActivity implements OnMarkerClickListener         private Marker myMarker             private void setUpMap                               googleMap setOnMarkerClickListener this          myMarker   googleMap addMarker new MarkerOptions                      position latLng                     title  My Spot                      snippet  This is my spot                       icon BitmapDescriptorFactory defaultMarker BitmapDescriptorFactory HUE AZURE                              Override   public boolean onMarkerClick final Marker marker             String name  marker getTitle           if  name equalsIgnoreCase  My Spot                         write your code here

I added a mMap setOnMarkerClickListener this   in the onMapReady GoogleMap googleMap  method  So every time you click a marker it displays the text name in the toast method    public class DemoMapActivity extends AppCompatActivity implements NavigationView OnNavigationItemSelectedListener OnMapReadyCallback  GoogleMap OnMarkerClickListener    private GoogleMap mMap    Override protected void onCreate Bundle savedInstanceState        super onCreate savedInstanceState       setContentView R layout activity places       Toolbar toolbar   findViewById R id toolbar       setSupportActionBar toolbar       SupportMapFragment mapFragment    SupportMapFragment  getSupportFragmentManager   findFragmentById R id map       mapFragment getMapAsync this       Override public void onMapReady GoogleMap googleMap        mMap   googleMap      double lat 0 34924212701428      double lng 32 616554024713      String venue    Capital Shoppers City       LatLng location   new LatLng lat  lng       mMap addMarker new MarkerOptions   position location  title venue   setTag 0       CameraUpdate cameraUpdate   CameraUpdateFactory newLatLng location       CameraUpdate zoom   CameraUpdateFactory zoomTo 16       mMap moveCamera cameraUpdate       mMap animateCamera zoom       mMap setOnMarkerClickListener this       Override public boolean onMarkerClick final Marker marker           Retrieve the data from the marker      Integer clickCount    Integer  marker getTag            Check if a click count was set  then display the click count      if  clickCount    null            clickCount   clickCount   1          marker setTag clickCount           Toast makeText this                         marker getTitle                              has been clicked                           Toast LENGTH SHORT  show                 Return false to indicate that we have not consumed the event and that we wish        for the default behavior to occur  which is for the camera to move such that the        marker is centered and for the marker s info window to open  if it has one       return false         You can check this link for reference Markers

All markers in Google Android Maps Api v2 are clickable  You don t need to set any additional properties to your marker  What you need to do - is to register marker click callback to your googleMap and handle click within callback   public class MarkerDemoActivity extends android support v4 app FragmentActivity     implements OnMarkerClickListener       private Marker myMarker           private void setUpMap                                 googleMap setOnMarkerClickListener this            myMarker   googleMap addMarker new MarkerOptions                        position latLng                       title  My Spot                        snippet  This is my spot                         icon BitmapDescriptorFactory defaultMarker BitmapDescriptorFactory HUE AZURE                                Override     public boolean onMarkerClick final Marker marker             if  marker equals myMarker                            handle click here                     here is a good guide on google about marker customization
