以下 Json 有路附近地方的经度和纬度。我希望这些线被折断到路上...但我尝试过，失败了。只想在道路上绘制折线，以便计算从一条道路 LatLang 到另一条道路的距离。

最好在您的问题中提供更多细节。我们不知道您已经尝试过什么。我还没有使用过Android的谷歌地图，但考虑到它使用得很好，记录在案，应该不会那么困难。
在 Google Dev 网站上快速搜索后，我会将您的 json 转换为更有用的东西，例如数组或对象，甚至是经度/经度的键值对。
然后，您需要将折线添加到Google地图对象中，以"绘制"每个坐标之间的线条。
// Instantiates a new Polyline object and adds points to define route
PolylineOptions rectOptions = new PolylineOptions()
.add(new LatLng(37.35, -122.0))
.add(new LatLng(37.45, -122.0))
.add(new LatLng(37.45, -122.2))
.add(new LatLng(37.35, -122.2))
.add(new LatLng(37.35, -122.0));
// Get back the mutable Polyline
Polyline polyline = myMap.addPolyline(rectOptions);
取自 https://developers.google.com/maps/documentation/android-api/shapes
还有一个GeoJSON实用程序，可以将地理位置点的JSONObject直接转换为地图。 https://developers.google.com/maps/documentation/android-api/utility/geojson
谷歌地图的大量教程从不介意谷歌自己的文档。
祝你好运
