You can always use the function .title()
of MarkerOptions
class for displaying title of a Marker.
Eg:-
MarkerOptions mOptions=new MarkerOptions();
mOptions.title('My_Marker_Title');
mOptions.position('My_Marker_Position'); // pass the current location here
mOptions.icon(BitmapDescriptorFactory.defaultMarker(BitmapDescriptorFactory.RED));
//default color is red here. You can change it.
Marker myMarker = map.addMarker(mOptions);
For My_Marker_position:-
LatLng ltlng=new LatLng(currentLocation.getLatitude(),currentLocation.getLongitude());
and use mOptions.position(ltlng);
You can use many functionalities with your marker too. Like adding snippet, making it draggable etc.
To show your marker info use:-
myMarker.showWindowInfo();
