问题描述

我试图用 ClusterManager ,以我的集群 CustomMapMarker S,但是当标记数据变化我称之为 mClusterManager.cluster()的旗杆位置不会改变。

I'm trying to use ClusterManager in order to cluster my CustomMapMarkers, but when the marker data changes and I call mClusterManager.cluster(), the pin positions don't change.

code:

地图更新方法

void updateMap() {
  mClusterManager.clearItems();
  mClusterManager.addItem(data.getMarker(id));
  mClusterManager.cluster();
}

标记更新方法

CustomMarker processMarkerUpdate(JSONObject json) {
  CustomMarker cm = new CustomMarker(json.optDouble("latitude", 0.0), json.optDouble("longitude",0.0));

  if (json.has("id")) {
    cm.setUid(json.getString("id"));
  } else {
    //If this happens, we stop processing.
    throw new InvalidCMException();
  }

  cm.setLabel(json.optString("label", ""));

  return cm;
}

我三重检查坐标和它们在对象变了,但标记没有在地图上移动。

I've triple checked the coordinates and they are changed in the object, but the marker does not move on the map.

我缺少的一个步骤?

推荐答案

我已经重写我的标记实现的散code()方法,它显然是造成散型集合平时替换的功能行事靠不住的。我的解决办法是删除我的自定义实现和解决需要它。

I had overridden my Marker implementation's hashCode() method, which was apparently causing the usual replacing functionality of hash-type collections to act wonky. My solution was to remove my custom implementation and work around the need for it.
