Question

如果已经回答，请提前道歉。我无法在线或在存储库中找到任何指向我的问题的内容。

我有一个ArrayList<Position>持有我的线路。

使用addPolyline

绘制时，此显示效果不错

我想设置线条，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。该地点位于英格兰坎布里亚郡，但是被索马里海岸所吸引。

我试图在每次转换后输出坐标，它们都显示正常。我无法弄清楚如何检查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Log s都相同的log cat输出在这里。

我的问题是;我做错了什么是我缺少的东西？

Answer 1

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

Mapbox GeoJSON处于错误的位置
