How to trigger the onClick event of a marker on a Google Maps V2 for Android?

Is there a way of calling onClick event of a specific marker manually (without physically tapping the marker)?

The GoogleMap object has a method Marker addMarker(mk: MarkerOptions) that returns a proper Marker instead of MarkerOptions.

So as soon as you add it you can simulate click behavior as follows:

fun addAndZoom(mk: MarkerOptions, needsHighlight: Boolean) {
    mapView.getMapAsync { map ->
        val actualMarker = map.addMarker(mk)
        if(needsHighlight) {
            val cameraUpdate = CameraUpdateFactory.newLatLngZoom(mk.position, 14F)
            map.animateCamera(cameraUpdate)
            actualMarker.showInfoWindow()
        }
    }
}

I just stumbled across this and wasn't helped by the answers. So for future readers - if you are adding a map.setOnMarkerClickListener(yourClickHandler), then it's quite straight forward.

Abstract the logic from yourClickHandler and keep a reference to all the markers... I.e. 

private val markers = arrayListOf<Marker>()

Wherever you add your markers to the map, also add them to your markers array. I.e. something like

val marker = MarkerOptions().position(...).......
markers.add(map.addMarker(marker))

And yourClickHandler would look something like

val yourClickHandler = GoogleMap.OnMarkerClickListener {
    markerClickHandler(marker = it)
    return@OnMarkerClickListener false
}

Now, whenever you press a marker on the map, yourClickHandler will call markerClickHandler() and whatever you do in there will happen. Also, when you wan't to press a marker programmatically, simply pass that marker to markerClickHandler.

You CAN simulate a marker click. Create your MyMarkerManager class extending from MarkerManager class.

The class has a function onMarkerClick() which you can call manually to simulate the event.

For more details refer this link. https://github.com/googlemaps/android-maps-utils/blob/master/library/src/com/google/maps/android/MarkerManager.java

No, but you can simulate the onClick event. 2 things happen when you click a marker:

  1. The info window for the corresponding clicked marker is shown.
  2. The camera pans to the marker.

The above can be achieved with 2 lines of code:

marker.showInfoWindow();
map.animateCamera(CameraUpdateFactory.newLatLng(marker.getPosition()), 250, null);

NO, you can't triger a marker click event directly (from code).

You can just use mMap.setOnMarkerClickListener(...);, to handle markers click event.

But there is an alternative if you use your map in WebView, so you can trigger a marker click event with JavaScript:

//In V2 version:
GEvent.trigger(markers[i], 'click');

//In V3 version:
google.maps.event.trigger(markers[i], 'click');

The answer is no. You can't set the onClick of a particular marker separately.

However , using Map.setOnMarkerClickListener(_) you can set a listener for all such events. You should be able to retrieve the marker object in the listener called whenever any marker is clicked . You can use some identification to see if this is the particular marker you desire and act accordingly. The identification could be any of the properties specific to that marker , title being the obvious choice. However, you can filter markers using any desired property.

Try this ,

Implement marker click listener from your map class , 

public class MapView extends FragmentActivity implements OnMarkerClickListener{}

it will override onMarkerClickEvent as follows , 

@Override
public boolean onMarkerClick(final Marker marker) {}
