我正在通过实时位置更新在街道上移动汽车 . 虽然移动它朝向方向正确定位，但是当运动停止时，汽车面向真北，无论我朝哪个方向，轴承都返回0.0 . 按照我正在使用的代码：
public static void animateMarker(Marker marker, Location destination) {
if (marker != null) {
LatLng startPosition = marker.getPosition();
LatLng endPosition = new LatLng(destination.getLatitude(), destination.getLongitude());
float startRotation = marker.getRotation();
LatLngInterpolator latLngInterpolator = new LatLngInterpolator.LinearFixed();
ValueAnimator valueAnimator = ValueAnimator.ofFloat(0, 1);
valueAnimator.setDuration(1000); // duration 1 second
valueAnimator.setInterpolator(new LinearInterpolator());
valueAnimator.addUpdateListener(animation -> {
try {
float v = animation.getAnimatedFraction();
LatLng newPosition = latLngInterpolator.interpolate(v, startPosition, endPosition);
marker.setPosition(newPosition);
marker.setRotation(computeRotation(v, startRotation, destination.getBearing()));
} catch (Exception ex) { }
});
valueAnimator.start();
}
}
private static float computeRotation(float fraction, float start, float end) {
float normalizeEnd = end - start; // rotate start to 0
float normalizedEndAbs = (normalizeEnd + 360) % 360;
float direction = (normalizedEndAbs > 180) ? -1 : 1; // -1 = anticlockwise, 1 = clockwise
float rotation;
if (direction > 0) {
rotation = normalizedEndAbs;
} else {
rotation = normalizedEndAbs - 360;
}
float result = fraction * rotation + start;
return (result + 360) % 360;
}
怎么解决这个？
