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

The word set in setOnInfoWindowClickListener means it overrides any value that was set before. This function is called on GoogleMap object and because there is one GoogleMap objects, there is one OnInfoWindowClickListener that is active.

The way you work with it is decide what happens based on the parameter in callback onInfoWindowClick(Marker marker) using if else, switch or maybe Map:

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

Of course you need to initialize this map earlier:

Marker marker1 = googlemap.addMarker...
map.put(marker1, Example.class);

Edit:

// on the class level:
private Map allMarkersMap = new HashMap();

// in the onCreate or elsewhere
Marker marker1 = googlemap.addMarker(new MarkerOptions()
    .position(new LatLng(0,-0))
    .title("Netherlands")
    .snippet("Amsterdam")    
    .icon(BitmapDescriptorFactory.fromResource(R.drawable.star)));
allMarkersMap.put(marker1, Example.class);

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