How do I keep a Google Map marker in the center of the map without lag?

问题

I'm trying to keep a marker in the center of the map when a user drags the camera.

I'm currently doing this by using an OnCameraChangeListener like so:

@Override
public void onCameraChange(CameraPosition position) {
    marker.setPosition(map.getCameraPosition().target);
}

My problem with this is lag. The marker flickers and doesn't stay in place perfectly until I stop dragging.

I'm assuming a better way of doing this is to add some sort of overlay over-top the map.

Any suggestions?

Yes. You are better of putting your MapFragment or MapView inside FrameLayout (or RelativeLayout) with another ImageView or anything else and setting its gravity to center.
