如何在Xamarin.Forms.Map中获取当前位置或移动到当前位置 [英] How to get current location or move to current location in Xamarin.Forms.Map

问题描述

由于地图已经显示了用户位置(使用IsShowingUser)，所以我只想缩放到该位置.这很容易实现，还是因为我找不到任何GeoLocation对象，所以我需要获取每个平台上的位置.只有GeoCoder ... 这不是放大用户位置的常见用例吗?

Since the Map already shows the user location (with IsShowingUser) I just want to zoom to this location. Is this easily possible or do I need to get the location on every platform, since I don't find any GeoLocation object. Only the GeoCoder... Is this not a common usecase to zoom to users position?

推荐答案

您需要使用感兴趣的位置调用MoveToRegion方法.

You will need to call MoveToRegion method with the position you are interested in.

您可以使用用于Xamarin的Geoolocator插件获取PCL项目中的位置:

You can use Geolocator Plugin for Xamarin to get the location in PCL project:

var locator = CrossGeolocator.Current;
var position = await locator.GetPositionAsync(10000);
map.MoveToRegion(MapSpan.FromCenterAndRadius(new Position(position.Latitude, position. Longitude), 
                                             Distance.FromMiles(1))
