离线地图 HERE-SDK - 离线搜索和导航

发布于 2025-01-10 13:04:41 字数 799 浏览 4 评论 0原文

我正在使用 HERE-Android-SDK 构建一个带有离线地图的简单导航解决方案。在使用离线模式搜索地址和计算路线时，我可以看到地址搜索返回的结果不包含在已安装的离线地图数据集中。为了仅获取位于我的设备上安装的离线地图数据内的搜索结果，我还需要做些什么吗？

我正在使用以下代码片段。

下载特定国家/地区的离线地图：

mapsLoader.selectDataGroup(MapPackage.SelectableDataGroup.TruckAttributes)
mapsLoader.installMapPackages(listOf(mapPackageId))

搜索地址请求：

val term = "New York"
val center = GeoCoordinate(lastWayPoint.latitude, lastWayPoint.longitude)
val request = SearchRequest(term)
request.connectivity = Request.Connectivity.OFFLINE
request.locale = Locale.GERMAN
request.setSearchCenter(center)
request.collectionSize = 5
request.execute { data, error -> 
  if (error != ErrorCode.NONE) return
  // handle search results here
}

提前感谢您的所有帮助！

I am using HERE-Android-SDK to build a simple navigation solution with offline maps.
While using the offline mode for the search addresses and calculation of a route, I can see that there are results returned from the address-search, which are not included in the installed offline map datasets. Is there anything additional which I need to do, in order to get only search results which are located inside the offline-map data installed on my device?

I am using the following code snippets.

download offline maps for a specific country:

mapsLoader.selectDataGroup(MapPackage.SelectableDataGroup.TruckAttributes)
mapsLoader.installMapPackages(listOf(mapPackageId))

search request for addresses:

val term = "New York"
val center = GeoCoordinate(lastWayPoint.latitude, lastWayPoint.longitude)
val request = SearchRequest(term)
request.connectivity = Request.Connectivity.OFFLINE
request.locale = Locale.GERMAN
request.setSearchCenter(center)
request.collectionSize = 5
request.execute { data, error -> 
  if (error != ErrorCode.NONE) return
  // handle search results here
}

Thanks for all of your help in advance!
