如果已经回答,请提前道歉。我在网上或存储库中找不到任何指向我的问题的东西。

我有一个ArrayList<Position>握住我的线刺痛的东西。

绘制时此显示很好addPolyline

我想设置线条的样式,所以我切换到使用线条图层。然而。

该线不再出现在靠近正确位置的任何地方。该位置位于英格兰坎布里亚郡,但位于索马里海岸。

我试图在每次转换后输出坐标,它们看起来都很好。我不知道如何检查source

Log.d("Tracing 1", route.toString())

val lineString = LineString.fromCoordinates(route)

Log.d("Tracing 2", lineString.coordinates.toString())

val feature = Feature.fromGeometry(lineString)

Log.d("Tracing 3", feature.geometry.coordinates.toString())

val featureCollection = FeatureCollection.fromFeatures(
        arrayOf(feature))

val geoJsonSource: Source = GeoJsonSource("line-source", featureCollection)
mapboxMap.addSource(geoJsonSource)

val debugSource = mapboxMap.getSource("line-source") as GeoJsonSource
Log.d("Tracing 4", debugSource.toString())

val lineLayer = LineLayer("linelayer", "line-source")

lineLayer.setProperties(
        PropertyFactory.lineDasharray(arrayOf(0.01f, 2f)),
        PropertyFactory.lineCap(LINE_CAP_ROUND),
        PropertyFactory.lineJoin(LINE_JOIN_ROUND),
        PropertyFactory.lineWidth(5f),
        PropertyFactory.lineColor(Color.parseColor("#e55e5e"))
)

mapboxMap.addLayer(lineLayer)

val cameraPosition = CameraPosition.Builder()
        .target(LatLng(route[0].latitude, route[0].longitude))
        .build()

mapboxMap.moveCamera(CameraUpdateFactory.newCameraPosition(cameraPosition))

显示Logs 都相同的 log cat 输出在这里。

我的问题是;我做错了什么我错过了什么吗?

对于 MapBox,您必须以相反的顺序提供纬度和经度。您的问题是您已经切换了每个点的经度和纬度坐标。
