[Maps] [Regression from Xamarin.Forms.Maps] Changing Location on a Pin does nothing #323

Open japarson opened 7 months ago

japarson commented 7 months ago

Description

Changing the Location property on a Microsoft.Maui.Controls.Maps.Pin does not change the location of the Pin on the map.

Steps to Reproduce

  1. Create a map.
  2. Add a pin at a location.
  3. Change the location of the pin: pin. Location = something;
  4. Observe that the pin does not change its location on the map.

Possible Fix

I believe the reason this doesn't work is this line:

https://github.com/dotnet/maui/blob/main/src/Core/maps/src/Handlers/MapPin/MapPinHandler.Android.cs#L14

        public static void MapLocation(IMapPinHandler handler, IMapPin mapPin)
        {
            if (mapPin.Location != null)
                handler.PlatformView.SetPosition(new LatLng(mapPin.Location.Latitude, mapPin.Location.Longitude));
        }

The handler maintains a MarkerOptions as its PlatformView and loses track of the Marker instance created in the MapHandler. So updating the Pin's Location property updates the MarkerOptions, which has already been used to create the Marker and is therefore no longer useful. The handler should keep track of the created Marker (which is present in a private list on the MapHandler) and update its Position property directly.

I also found the following external resources that might be helpful: **Summaries of links found in the content:** https://github.com/dotnet/maui/blob/main/src/Core/maps/src/Handlers/MapPin/MapPinHandler.Android.cs#L14: The page is a source code file for the Android implementation of the MapPinHandler class in the Microsoft.Maui.Controls.Maps namespace. The problem described is that changing the Location property of a Pin does not update the location of the Pin on the map. The suggested fix is to modify the MapLocation method in the MapPinHandler.Android.cs file. The current implementation sets the position of the PlatformView (MarkerOptions) based on the Pin's Location property. However, this approach is incorrect because the PlatformView is already used to create the Marker and cannot be updated. The suggested fix is to modify the MapLocation method to keep track of the created Marker and update its Position property directly.
