infowindow not showing hashmap data

Question

Hello I have some markers created form data in a listarray. These are created properly then I add the data to be shown in the infowindow of each marker to a hashmap.

But the infowindow does not seem to read the hashmap data, not sure where I'm going wrong.

The debugging tags I have all show that the data gets properly stored in the hashmap upon creating markers.

then in the infowindow the right markerid is recognized but the hashmap data linked to that makerid does not show, all markers show infowindow with same data.

public class MapFragment extends Fragment implements OnMapReadyCallback {

static final LatLng Loc2 = new LatLng(12.106011, -68.935108);
private GoogleMap map;
private ArrayList<Customer> customerList = new ArrayList<>();
private HashMap<String, HashMap<String, String>> outerMap = new HashMap<String, HashMap<String, String>>();
private HashMap<String, String> innerMap = new HashMap<String, String>();
private Marker marker;
final String TAG3 = "MapFragment:";

public MapFragment() {

    return view;

Just create a new instance of innerMap for each customer.

Remove this line:

private HashMap<String, String> innerMap = new HashMap<String, String>();

And in your setMarker() method add this:

Map<String, String> innerMap = new HashMap<String, String>();

Your setMarker() method will look like this:

private void setMarker(){
    for(Customer customer : customerList){
        //...

        Map<String, String> innerMap = new HashMap<String, String>(); // Add this line

        innerMap.put("Name", name);
        innerMap.put("Address",address);
        innerMap.put("Tel",tel);

        //...
    }
}
