android - 根据 OSMDroid 的一组位置确定合适的缩放级别

Question

从 Google Maps Android API v2 中，我了解到这可以通过以下方法完成:

LatLngBounds.Builder builder = new LatLngBounds.Builder();
for (Location loc : allLocations) {
    LatLng position = new LatLng(loc.getLatitude(), loc.getLongitude());
    builder.include(position);
}

CameraUpdate cu = CameraUpdateFactory.newLatLngBounds(builder.build(), someMarginValue);
map.moveCamera(cu);

但是我似乎找不到为 OSMDroid 执行此操作的方法。是否有解决方案/类可以帮助根据一组位置确定缩放级别？

这对我来说效果很好:

    ArrayList<GeoPoint> waypoints = new ArrayList<GeoPoint>();
    waypoints.add(new GeoPoint(35.37, -119.01));
    waypoints.add(new GeoPoint(35.35, -119.01));
    waypoints.add(new GeoPoint(35.11, -118.32));
    waypoints.add(new GeoPoint(35.10, -118.32));
    waypoints.add(new GeoPoint(35.10, -118.15));
    waypoints.add(new GeoPoint(35.09, -118.14));
    waypoints.add(new GeoPoint(35.63, -117.88));
    waypoints.add(new GeoPoint(35.65, -117.72));
    waypoints.add(new GeoPoint(35.62, -117.67));

    final BoundingBoxE6 boundingBoxE6 = BoundingBoxE6.fromGeoPoints(waypoints);
    mMapView.zoomToBoundingBox(boundingBoxE6,true);
