从 MVVM Googlemap Xamarin 绑定折线

Question

从 Google 地图 Api 获取位置并希望在两点之间创建折线，但问题是折线 -> GeoPath 是只读的。如何将Positions赋给GeoPath或者直接绑定position到地图？

我正在使用以下 this sample

Map map = new Map
{
// ...
};
// instantiate a polyline
Polyline polyline = new Polyline
{
StrokeColor = Color.Blue,
StrokeWidth = 12,
Geopath =
{
new Position(47.6381401, -122.1317367),
new Position(47.6381473, -122.1350841),
new Position(47.6382847, -122.1353094),
new Position(47.6384582, -122.1354703),
new Position(47.6401136, -122.1360819),
new Position(47.6403883, -122.1364681),
new Position(47.6407426, -122.1377019),
new Position(47.6412558, -122.1404056),
new Position(47.6414148, -122.1418647),
new Position(47.6414654, -122.1432702)
}
};

// add the polyline to the map's MapElements collection
map.MapElements.Add(polyline);

Answer 1

折线 -> Geopath -> 添加将解决问题

Polyline polyline = new Polyline
{
StrokeColor = Color.Blue,
StrokeWidth = 12
}
polyline.GeoPath.Add(new Position)
