我正试图在驾车路线上的谷歌地图上移动标记。我设法为地图上的标记设置动画，但我无法根据特定路线移动它。提前感谢任何帮助。 这是我用来制作动画的标记代码：Google地图标记动画
final long duration = 11200;
final Handler handler = new Handler();
final long start = SystemClock.uptimeMillis();
Projection proj = googleMap.getProjection();
Point startPoint = proj.toScreenLocation(marker.getPosition());
final LatLng startLatLng = proj.fromScreenLocation(startPoint);
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 * target.longitude + (1 - t) * startLatLng.longitude;
double lat = t * target.latitude + (1 - t) * startLatLng.latitude;
LatLng posetion2=new LatLng(lat,lng);
CameraPosition cameraPosition =
new CameraPosition.Builder()
.target(posetion2)
.bearing(9)
.tilt(10)
.zoom(googleMap.getCameraPosition().zoom)
.build();
googleMap.animateCamera(
CameraUpdateFactory.newCameraPosition(cameraPosition)
);
