I want to implement smooth transition to emulate car marker moving on the map.
Is it possible to animate marker in android map api v2?
Try out the below code to animate the marker on Google Map V2.
You need to use the Interpolator
class to apply the animation on the Marker and handle it in the Handler for the animation as below:
public void animateMarker(final Marker marker, final LatLng toPosition, final boolean hideMarker) { final Handler handler = new Handler(); final long start = SystemClock.uptimeMillis(); Projection proj = mGoogleMapObject.getProjection(); Point startPoint = proj.toScreenLocation(marker.getPosition()); final LatLng startLatLng = proj.fromScreenLocation(startPoint); final long duration = 500; final Interpolator interpolator = new LinearInterpolator(); handler.post(new Runnable() { @Override public void run() { long elapsed = SystemClock.uptimeMillis() - start; float t = interpolator.getInterpolation((float) elapsed / duration); double lng = t * toPosition.longitude + (1 - t) * startLatLng.longitude; double lat = t * toPosition.latitude + (1 - t) * startLatLng.latitude; marker.setPosition(new LatLng(lat, lng)); if (t < 1.0) { // Post again 16ms later. handler.postDelayed(this, 16); } else { if (hideMarker) { marker.setVisible(false); } else { marker.setVisible(true); } } } }); }
