android – Google Map v2 Marker Animation

Posted by: admin June 15, 2020 Leave a comment


Do anyone have idea how this animation’s implementation is possible in google map api v2.
Check out this here.
I would like to know how this is done. Please let me know if anyone have any sample code regarding this.

Thanks in advance.

How to&Answers:

I found a solution that worked for me:

final LatLng target = NEW_LOCATION;

final long duration = 400;
final Handler handler = new Handler();
final long start = SystemClock.uptimeMillis();
Projection proj = map.getProjection();

Point startPoint = proj.toScreenLocation(marker.getPosition());
final LatLng startLatLng = proj.fromScreenLocation(startPoint);

final Interpolator interpolator = new LinearInterpolator();
handler.post(new Runnable() {
    public void run() {
        long elapsed = SystemClock.uptimeMillis() - start;
        if (elapsed > duration) {
            elapsed = duration;
        float t = interpolator.getInterpolation((float) elapsed / duration);
        double lng = t * target.longitude + (1 - t) * startLatLng.longitude;
        double lat = t * target.latitude + (1 - t) * startLatLng.latitude;
        marker.setPosition(new LatLng(lat, lng));
        if (t < 1.0) {
            // Post again 10ms later.
            handler.postDelayed(this, 10);
        } else {
            // animation ended


You are welcome to change the position of a Marker at any point by calling setPosition(). You are welcome to change the position of the “camera” (i.e., the map’s center and zoom level) at any point by applying a CameraUpdate object using moveTo() or animateTo() on GoogleMap. Combining these with a light timing loop (e.g., using postDelayed()) should allow you to achieve a similar animation effect.


Great news is that he Google Map API v2 gives the new Camera controls.
You can check the new features and how to use them directly here on the Youtube channel of the Android developers team.

It also provides animate, tilt, bearing … but I think the video is very detailed and also talks about applications like the one in your example.

Have fun, and give me a link when you finish your app.
