Android Google Maps, How to Make Each Marker Infowindow Open Different Activity

Android Google Maps, how to make each Marker InfoWindow open different Activity?

Use a HashMap to store the marker ID and it's corresponding identification of which Activity it should open.

Then, use a OnInfoWindowClickListener to get the event of a user clicking the info window, and use the HashMap to determine which Activity to open.

Declare the HashMap as an instance variable:

//Declare HashMap to store mapping of marker to Activity
HashMap<String, String> markerMap = new HashMap<String, String>();

Then, each time you add a Marker, make an entry in the HashMap:

        String id = null;

        Marker a1 = googleMap.addMarker(new MarkerOptions().position(a)
                .title(arr[0])
                .snippet(arr[1]));

        id = a1.getId();
        markerMap.put(id, "a1");

        Marker b1 = googleMap.addMarker(new MarkerOptions().position(b)
                .title(arr[9])
                .snippet(arr[10]));

        id = b1.getId();
        markerMap.put(id, "b1");

        Marker c1= googleMap.addMarker(new MarkerOptions().position(c)
                .title(arr[18])
                .snippet(arr[19]));

        id = c1.getId();
        markerMap.put(id, "c1");

        Marker d1= googleMap.addMarker(new MarkerOptions().position(d)
                .title(arr[27])
                .snippet(arr[28]));

        id = d1.getId();
        markerMap.put(id, "d1");
    }

And then define the info window click listener:

    googleMap.setOnInfoWindowClickListener(new GoogleMap.OnInfoWindowClickListener() {
        @Override
        public void onInfoWindowClick(Marker marker) {

            String m = markerMap.get(marker.getId());

            if (m.equals("a1")){
                Intent i = new Intent(MainActivity.this, ActivityA1.class);
                startActivity(i);
            }
            else if (m.equals("b1")){
                Intent i = new Intent(MainActivity.this, ActivityB1.class);
                startActivity(i);
            }
            else if (m.equals("c1")){
                Intent i = new Intent(MainActivity.this, ActivityC1.class);
                startActivity(i);
            }
            else if (m.equals("d1")){
                Intent i = new Intent(MainActivity.this, ActivityD1.class);
                startActivity(i);
            }
        }
    });

Can I launch other activites from different markers on Google Maps?

You can try using declaring a new HashMap data structure. When you're adding the markers to the map, you can put the Hely object into the map like so:

HashMap<String, Hely> helyMap = new HashMap<>();
//... code to create the marker ...//
markers.add(marker);
helyMap.put(marker.getId(), hely);

Then, in the onInfoWindowClick(Marker marker) method retrieve the Hely object based on the marker that was clicked like so:

Hely hely = helyMap.get(marker.getId());
Intent intent = new Intent(getApplicationContext(), HelyDetailActivity.class);
intent.putExtra(ListActivity.HELY_NEV_EXTRA, hely.getHelynev());
// ... other intent code ... //
startActivity(intent);

Android google maps markers with different values on Info Window

Use a HashMap

I'm not sure if this is the best solution but it works. Basically I just added the marker into a HashMap and passed this HashMap to my Custom Info Window class.

Adding the markers:

HashMap<Marker, JSONObject> stopsMarkersInfo = new HashMap<>(); // created the HashMap
JSONArray stops = new File().getStops(lineId);
for (int i = 0; i < stops.length(); i++) {
    BitmapDescriptor stopMarkerIcon = new File().getStopMarkerIcon(color, Integer.parseInt(stops.getJSONObject(i).getString("sequence")));
    LatLng coordinate = new LatLng(Double.parseDouble(stops.getJSONObject(i).getString("lat")), Double.parseDouble(stops.getJSONObject(i).getString("lng")));
    MarkerOptions markerOptions = new MarkerOptions().icon(stopMarkerIcon).position(coordinate).anchor(.5f, .5f);
    Marker marker = googleMap.addMarker(markerOptions);
    stopsMarkersInfo.put(marker, stops.getJSONObject(i)); // added each marker and 
                                                          // his information to the HashMap
}
googleMap.setInfoWindowAdapter(new StopsInfoWindow(stopsMarkersInfo)); // passed the HashMap

Info Window Adapter:

public class StopsInfoWindow implements GoogleMap.InfoWindowAdapter {

    private HashMap<Marker, JSONObject> stopsMarkersInfo;
    private View view;

    public StopsInfoWindow(HashMap<Marker, JSONObject> stopsMarkersInfo) {
         this.stopsMarkersInfo = stopsMarkersInfo;
    }

    @Override
    public View getInfoContents(Marker marker) {
         return null;
    }

    @Override
    public View getInfoWindow(final Marker marker) {
        JSONObject stop = stopsMarkersInfo.get(marker);
        if (stop != null) {
            LayoutInflater inflater = (LayoutInflater) Controller.getContext().getSystemService(Context.LAYOUT_INFLATER_SERVICE);
            view = inflater.inflate(R.layout.item_stop_marker_info, null);

            TextView stopName = (TextView) view.findViewById(R.id.stop_name);
            stopName.setText(stop.getString("name"));

            TextView stopLine = (TextView) view.findViewById(R.id.stop_line);
            stopLine.setText(stop.getString("line"));
        }
        return view;
    } 
}

Android Google Map v2 - Starting activity when clicking on marker infoWindow

add this to your code

 Mymap.setOnInfoWindowClickListener(new OnInfoWindowClickListener() {
            @Override
            public void onInfoWindowClick(Marker marker) {
               Intent intent = new Intent(MapActivity.this,OtherActivity.class);
               startActivity(intent);

            }
        });

How to open different activities depending OnInfoWindowClick

you are checking like this in your if clause:

if (googleMap.equals("Durban")) {
      Intent intent = new Intent(MainActivity.this, Durban.class);
      startActivity(intent);
}

but you should check on the marker of the public void onInfoWindowClick(Marker marker) method.

do something like this:

if (marker.getTitle().equals("Durban")) {
      Intent intent = new Intent(MainActivity.this, Durban.class);
      startActivity(intent);
}

Sending data through InfoWindow to another activity Android

Try this way, You will get different value on InfoWindow Click if your bean (details) have different value.

 for (final infoToStore details : info) {
        marker = mMap.addMarker(new MarkerOptions()
                .position(new LatLng(Double.parseDouble(details.getLat()), Double.parseDouble(details.getLng())))
                .title(details.getName())
                .snippet(details.getDesc()));
         // Attach your bean with marker
        marker.setTag(details);

        mMap.setOnInfoWindowClickListener(new GoogleMap.OnInfoWindowClickListener() {
            @Override
            public void onInfoWindowClick(Marker marker) {
                //Get Attached bean from marker
                infoToStore infoAttached = ((infoToStore) marker.getTag());

                Intent intent = new Intent(MainActivity.this, InfoWindow.class);
                intent.putExtra(NAME, infoAttached.getName());
                intent.putExtra(DESCRIPTION, infoAttached.getDesc());
                intent.putExtra(CATEGORY, infoAttached.getCat());
                intent.putExtra(IMAGE_URL, infoAttached.getUrl());
                intent.putExtra(PUSH_ID, infoAttached.getPushID());
                startActivity(intent);

            }
        });
    }
