Android中的SKMaps不显示多个注释

Question

我想在SKMaps中显示多个批注，但不能显示多个批注。例如，如果我将以下代码放入：

SKAnnotation annotation = new SKAnnotation(0);
    annotation.getLocation().setLongitude(-15.453439196571708);
    annotation.getLocation().setLatitude(28.097941791638732);
    annotation.setMininumZoomLevel(2);
    annotation.setAnnotationType(SKAnnotation.SK_ANNOTATION_TYPE_RED);
    mapView.addAnnotation(annotation, SKAnimationSettings.ANIMATION_POP_OUT);

我可以在我的地图中看到注释，但是如果我把这段代码放在显示多个注释的地方，我看不到多个注释：

startPoint = currentPosition.getCoordinate();

    viaPoints.clear();
    viaPoints.add(new SKViaPoint(1, new SKCoordinate(28.097941791638732, -15.453439196571708)));
    viaPoints.add(new SKViaPoint(2, new SKCoordinate(28.098324090242386, -15.454540411010385)));
    viaPoints.add(new SKViaPoint(3, new SKCoordinate(28.097633169963956, -15.455050952732563)));
    viaPoints.add(new SKViaPoint(4, new SKCoordinate(28.096485435962677, -15.455639194697142)));

    destinationPoint = new SKCoordinate(28.10000809840858, -15.455355048179626);

    for (SKViaPoint viaPointCurrent : viaPoints){
        SKAnnotation annotation = new SKAnnotation(viaPointCurrent.getUniqueId());
        annotation.getLocation().setLongitude(viaPointCurrent.getPosition().getLongitude());
        annotation.getLocation().setLatitude(viaPointCurrent.getPosition().getLatitude());
        annotation.setMininumZoomLevel(2);
        annotation.setAnnotationType(SKAnnotation.SK_ANNOTATION_TYPE_MARKER);
        mapView.addAnnotation(annotation, SKAnimationSettings.ANIMATION_POP_OUT);
    }

有什么问题吗？有人能帮帮我吗？

我刚刚在demo项目(2.5.1)中尝试了以下代码，覆盖了“注解”示例，所有内容都如预期的那样显示：

/**
 * Draws annotations on map
 */
private void prepareAnnotations() {
    List<SKViaPoint> viaPoints = new ArrayList<SKViaPoint>();
    viaPoints.add(new SKViaPoint(1, new SKCoordinate(28.097941791638732, -15.453439196571708)));
    viaPoints.add(new SKViaPoint(2, new SKCoordinate(28.098324090242386, -15.454540411010385)));
    viaPoints.add(new SKViaPoint(3, new SKCoordinate(28.097633169963956, -15.455050952732563)));
    viaPoints.add(new SKViaPoint(4, new SKCoordinate(28.096485435962677, -15.455639194697142)));

    //destinationPoint = new SKCoordinate(28.10000809840858, -15.455355048179626);

    for (SKViaPoint viaPointCurrent : viaPoints) {
        SKAnnotation annotation = new SKAnnotation(viaPointCurrent.getUniqueId());
        annotation.getLocation().setLongitude(viaPointCurrent.getPosition().getLongitude());
        annotation.getLocation().setLatitude(viaPointCurrent.getPosition().getLatitude());
        annotation.setMininumZoomLevel(2);
        annotation.setAnnotationType(SKAnnotation.SK_ANNOTATION_TYPE_MARKER);
        mapView.addAnnotation(annotation, SKAnimationSettings.ANIMATION_POP_OUT);
    }
    // set map zoom level
    mapView.setZoom(13);
    // center map on a position
    mapView.centerMapOnPosition(new SKCoordinate(28.097941791638732, -15.453439196571708));
}
