带有 CameraUpdateFactory.newCameraPosition 的 Android-animateCamera 不缩放

Question

我有一个 onClusterItemClickListener。我希望谷歌地图 (v2) 动画到那个位置，所以我使用 CameraUpdateFactory.newCameraPosition。

问题:google maps 动画到目标 LatLng 但不缩放、倾斜等。我用 GoogleMap.CancelableCallback() 进行了故障排除，似乎在动画到位置 onCancel() 之后总是被调用。

这是我的代码

...<some code before>
@Override
public boolean onClusterItemClick(OffersMarker item) {
   final LatLng markerLocation = item.getPosition();
   final OffersMarker i = item;
   final CameraPosition MARKER_POS = new CameraPosition.Builder()
      .target(markerLocation)
      .zoom(22)
      .bearing(0)
      .tilt(25)
      .build();

   gmap.animateCamera(CameraUpdateFactory.newCameraPosition(MARKER_POS));
}

此代码仅针对没有缩放或倾斜的目标进行动画处理。

这是带有故障排除的版本二

  @Override
public boolean onClusterItemClick(OffersMarker item) {
   final LatLng markerLocation = item.getPosition();
   final OffersMarker i = item;
   final CameraPosition MARKER_POS = new CameraPosition.Builder()
      .target(markerLocation)
      .zoom(22)
      .bearing(0)
      .tilt(25)
      .build();

   changeCamera(gmap, CameraUpdateFactory.newCameraPosition(MARKER_POS), new GoogleMap.CancelableCallback() {
       @Override
       public void onFinish() {
            Log.d("CAM_MOVE", "Finished animate camera");
       }
       @Override
       public void onCancel() {
             Log.d("CAM_MOVE", "Canceled animate camera");
       }
   });
}

这里是换相机的方法

private void changeCamera(GoogleMap map, CameraUpdate cameraUpdate, GoogleMap.CancelableCallback cancelableCallback) {
    map.animateCamera(cameraUpdate, cancelableCallback);
}

onCancel() 总是被未知来源调用。

我不确定它们是否已连接(调用 onCancel() 并且缩放不起作用)但它也可能是。非常感谢任何帮助。

所以解决方案隐藏在 click listener returning false 中因此默认方法开始起作用。

解决方法:在onClick代码后返回true。

例子

 private void addClusterItemClickListener(GoogleMap map, ClusterManager cM){
    final GoogleMap gmapI = map;
    cM.setOnClusterItemClickListener(new ClusterManager.OnClusterItemClickListener<OffersMarker>() {
        @Override
        public boolean onClusterItemClick(OffersMarker item) {
            Log.d("CAM_MOVE", "Clicked on marker");
            final LatLng markerLocation = item.getPosition();
            final OffersMarker i = item;
            if (markerLocation != null) {
                //Log.d("GEO_CODE_CRASH", "Latitude: " + markerLocation.latitude + " | " + "Longitude: " + markerLocation.longitude);
                //Log.d("CAM_MOVE", "Moving on with placeSelectHandler");
                placeSelectedHandler(markerLocation.latitude, markerLocation.longitude);
                buildingFragment.setNrOfOffersOnToolber(i.getNrOfOffers());
                getServerResponseAndPopulateBuildingPage(adr,markerLocation);

                CameraUpdate update = CameraUpdateFactory.newLatLngZoom(markerLocation, ZOOM_LEVEL_BUILDING);
                gmap.animateCamera(update);

            }
            return true; //<------- THIS NEEDS TO BE TRUE
        }
    });
}
