Question

我只是想知道是否可以允许用户打开或将自己的KML / KMZ文件加载到Here Maps的移动html5版本中，并让它们通过api中包含的图层按钮激活或停用kml图层？

Answer 1

目前看起来不太可能。 addLayer（）方法可用于添加叠加层，如下所示，但未设置为读取KML。如果您正在考虑加载KML，那么最好使用Maps API for JavaScript，如本示例所示http://developer.here.net/apiexplorer/examples/api-for-js/data-visualization/display-data-on-map.html

或者你可以查看jHERE库，它确实从底层库中公开了KML支持。

由于Mobile HMTL5库不提供折线实现，因此很难将KML路径添加到地图中，但可以使用JavaScript库加载一组标记的数据然后添加标记使用 addPOI（）方法，但这似乎相当复杂。

这是一个基于按下按钮的工作叠加层：
