Google Maps Android API v2 - MarkerOptions draggable and visible methods

问题

I'm playing with the new Google Maps Android API (v2) released earlier this month and I was delighted to see a MarkerOptions.draggable(boolean draggable) method which I thought would create a draggable marker when passing in a draggable value of true. However, on trying it (i.e. adding a marker as such to the map), it doesn't seem to do anything.

The MarkerOptions.visible(boolean visible) method too, which I thought would hide the marker from view when passing in a visible value of false.

Anyone been able to get these methods to work?

The latter issue is already in the Google Bug Tracker.

The draggable method should work. Look at the provided Sample project. Maybe the drag starts after a longpress, like in the Sample project?

    // Creates a draggable marker. Long press to drag.
    mMelbourne = mMap.addMarker(new MarkerOptions()
            .position(MELBOURNE)
            .title("Melbourne")
            .snippet("Population: 4,137,400")
            .draggable(true));
