how to add a title to a marker after the marker has been added to the google maps in android google maps api

Question

I am creating an app which can show the navigation path between two points in the google maps API in Android. When user clicks on the map somewhere, a marker is added at that place. When user clicks 2nd time, another marker is added and optimized navigation path is shown to the user in my application.

There is a JSON file provided by https://maps.googleapis.com/maps/api/directions/ which contains address of origin and destination. I have parsed that JSON file and stored the addresses.

Now the problem is, I have added the origin and destination markers already to the map by clicking on the map. and I want to provide title (address) to both the markers. But I guess we can not change the details after we have added the markers in the map.

Please reply. Thanks in advance.

Answer 1

 marker = mMap.addMarker(new MarkerOptions()
                .position(latLng)
                .title("Perth")
                .flat(true));
         .snippet("Population: 1,738,800"));

.title for setting tittle and .snippet for little details under title aand this code to method addMarkersToMap() and if you click on marker it'll appear and disppear

You need to keep Marker after adding MarkerOptions to the map. Let me show you an example of what should be done:

 GoogleMap map = ... // get a map.
 // Add a marker at San Francisco.
 Marker marker = map.addMarker(new MarkerOptions()
 .position(new LatLng(37.7750, 122.4183))
 .title("San Francisco")
 .snippet("Population: 776733"));

 marker.setTitle("MY MARKER'S NEW TITLE")

You can change marker tile by marker.setTitle("title") method and then refresh the marker-view by following

marker.hideInfoWindow();
marker.showInfoWindow();
