我试图加载此网页地图(https://oebb.maps.arcgis.com/home/item.html?id=f89eab37e55540f7b2e25a88cd0a07d5),但大多数图层都没有显示出来。 它适用于网络,但在Android上失败(使用最新的sdk,100.2.1)。

class MainActivity : AppCompatActivity() {

    lateinit var mMapView: MapView

    private lateinit var map: ArcGISMap

    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContentView(R.layout.activity_main)

        // inflate MapView from layout
        mMapView = findViewById(R.id.mapview)


        val leftPoint = Point(16.374120968073157, 48.186396114084104, SpatialReferences.getWgs84())
        val rightPoint = Point(16.38101960965946, 48.18357774813336, SpatialReferences.getWgs84())
        val initialExtent = Envelope(leftPoint, rightPoint)

        //construct a map from the portal item
        map = ArcGISMap("https://oebb.maps.arcgis.com/home/item.html?id=f89eab37e55540f7b2e25a88cd0a07d5")

        // set starting envelope for the ArcGISMap
        map.initialViewpoint = Viewpoint(initialExtent)

        // Pass a WebMap to the MapView constructor overload to display it.
        mapview.map = map

    }

    override fun onPause() {
        super.onPause()
        mMapView.pause()
    }

    override fun onResume() {
        super.onResume()
        mMapView.resume()
    }

    override fun onDestroy() {
        super.onDestroy()
        mMapView.dispose()
    }
}

10个图层中的9个有一个例外(map.operationalLayer [0] .loadError:ArcGISRuntimeException:无效的JSON。

您的代码似乎不错,问题可能出在加载Web地图的100.2.1 Android SDK内部。此问题应在几周后发布的100.3.0版中修复。我在内部版本上运行您的代码,并且渲染的图层和符号类似于网络版本。
