Android Google Maps V2 - OnInfoWindowClick on several markers

Question

I have the code to make one marker start a activity when you click on the infowindow. It works absolutely fine. But when I try to add in another marker and another @override

Answer 1

From MaciejGórski's help here is the example of having different classes(activities e.g pages) open when you click separate Marker infowindows on GoogleMapsV2:

add this in your GoogleMap class level:

private GoogleMap googlemap/mMap (or whatever you call yours); 
private Map allMarkersMap = new HashMap();

Underneath protected void onCreate (Bundle savedInstanceState) { super.onCreate(savedInstanceState); put in your markers:

    Marker marker = googlemap.addMarker(new MarkerOptions()
    .position(new LatLng(0,-0))
    .title("London")
    .snippet("North London")    
    .icon(BitmapDescriptorFactory.fromResource(R.drawable.star)));
    allMarkersMap.put(marker, NorthLondon.class);
    googlemap.setOnInfoWindowClickListener(this);



    Marker marker1 = googlemap.addMarker(new MarkerOptions()
    .position(new LatLng(0244534,-1232312))
    .title("USA")
    .snippet("Washington")    
    .icon(BitmapDescriptorFactory.fromResource(R.drawable.star)));
    allMarkersMap.put(marker1, Washington.class);
    googlemap.setOnInfoWindowClickListener(this);


    Marker marker2 = googlemap.addMarker(new MarkerOptions()
    .position(new LatLng(42343244,-0.334322))
    .title("Italy")
    .snippet("Rome"));
    allMarkersMap.put(marker2, Rome.class);
    googlemap.setOnInfoWindowClickListener(this);

    }

    public void onInfoWindowClick(Marker marker) {
    Class cls = allMarkersMap.get(marker);
    Intent intent = new Intent(MainActivity.this, cls);
    startActivity(intent);

}

The above are the separate markers. If I was to create another one I would call it Marker marker3, then 4,5 ect... Where it asks for .class in allMarkersMap.put(marker, .class); input the class you want, so it opens what you want. Have the public void OnInfoWindowClick code underneath the markers somewhere, this is the callback.

And that's it. When you click on InfoWindows in markers they should open the activity class you have put in the MarkerOptions code!
