Question

我有一个Android和iOS的Xamarin Forms Portable应用程序。我的地图一直很好，仍然在iOS中，但在Android中，我只是得到了整个世界的地图。这是AndroidManifest：

Mixed Content: The page at 'https://**.herokuapp.com/users' was loaded over HTTPS, but requested an insecure resource 'http://localhost:5000/api/users'. This request has been blocked; the content must be served over HTTPS.

这是Android和iOS展位的页面。

<uses-sdk android:minSdkVersion="19" android:targetSdkVersion="25" />
<uses-feature android:glEsVersion="0x00020000" android:required="true" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_LOCATION_EXTRA_COMMANDS" />
<uses-permission android:name="android.permission.ACCESS_MOCK_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="com.google.android.providers.gsf.permission.READ_GSERVICES" />
<uses-permission android:name="android.permission.WAKE_LOCK" /> 
<uses-permission android:name="android.permission.CALL_PHONE" />
<application android:label="MyProject" android:icon="@drawable/appicon">
<meta-data android:name="com.google.android.maps.v2.API_KEY" android:value="AIzaS...................................." />
<meta-data android:name="com.google.android.gms.version" android:value="@integer/google_play_services_version" />

myMap.MoveToRegion什么都不做。设置所有引脚都是如此，但没有任何反应，仍然是整个世界的地图。

            <controls:CustomMap x:Name="myMap" MapType="Street"
                WidthRequest="{x:Static local:App.ScreenWidth}"
                HeightRequest="{x:Static local:App.ScreenHeight}" />
        </StackLayout>
    </ContentPage.Content>
</ContentPage>

我注意到在customMapRenderer上if（e.PropertyName.Equals（“VisibleRegion”）＆amp;＆amp;！isDrawn）永远不等于VisibleRegion。首先是渲染器，然后是Y，然后是宽度和最后高度。

namespace MyProject.Pages
{
    public partial class LocationsPage : ContentPage
    {
        LocationsViewModel LocationsVM { get; set; }
        public List<LocationsResponse> Locations { get; set;}
        public LocationsPage()
        {
            InitializeComponent();
            myMap.MoveToRegion(
                            MapSpan.FromCenterAndRadius(
                                new Position(26.142051, -81.794683), Distance.FromMiles(4)));
        }

        protected override void OnBindingContextChanged()
        {
            base.OnBindingContextChanged();
            if (this.BindingContext != null)
            {
                LocationsVM = this.BindingContext as LocationsViewModel;
                if (LocationsVM.Locations != null)
                {
                    Locations = LocationsVM.Locations;
                    foreach (var location in Locations)
                    {
                        var latitude = Convert.ToDouble(location.Latitude);
                        var longitude = Convert.ToDouble(location.Longitude);                       
                        var label = $"{location.Name} - {location.Plaza}";
                        var address = $"{location.Street} {location.Citystate}";
                        var pin = new CustomPin
                        {
                            Pin = new Pin
                            {
                                Type = PinType.Place,
                                Position = new Position(latitude, longitude),
                                Label = label,
                                Address = address
                            },
                            Hours = location.Hours,
                            Phone = location.Phone,
                            Id="Myname",
                            Url = "http://www.myname.com"
                        };

                        myMap.CustomPins = new List<CustomPin> { pin };
                        myMap.Pins.Add(pin.Pin);
                    }

                }

            }

        }
    }
}

我接手了这个代码，我是Xamarin的新手谢谢你的帮助。
