How to know which Marker was clicked on Google Maps v2 for Android?

Question

I am making an application with a Google Maps on it, for Android. I have plenty of Markers on my screen and I am preparing customizable balloon for each marker when they are

Answer 1

There is a better option, and this is what google suggests:

Tag : An Object associated with the marker. For example, the Object can contain data about what the marker represents. This is easier than storing a separate Map. As another example, you can associate a String ID corresponding to the ID from a data set. Google Maps Android API neither reads nor writes this property.

So you can do something like this:

for (ListItem it: mList) {
    Marker mk = mMap.addMarker(new MarkerOptions().position(it.getLatLng()).title(it.getName()).snippet(it.getAddress()));
    mk.setTag(it.getID());
}

mMap.setOnMarkerClickListener(new GoogleMap.OnMarkerClickListener() {
    @Override
    public boolean onMarkerClick(Marker marker) {
        Integer id = (Integer) marker.getTag();
        return false;
    }
});
