将样式化的谷歌地图与Xamarin Android一起使用

Question

>有谁知道如何在Xamarin android上使用样式化的谷歌地图？Google最近添加了从此处创建样式地图的功能 https://mapstyle.withgoogle.com/，他们展示了如何使用它的示例

。

private void setSelectedStyle() {
    MapStyleOptions style;
    switch (mSelectedStyleId) {
        case R.string.style_label_retro:
            // Sets the retro style via raw resource JSON.
            style = MapStyleOptions.loadRawResourceStyle(this, R.raw.mapstyle_retro);
            break;
        case R.string.style_label_night:
            // Sets the night style via raw resource JSON.
            style = MapStyleOptions.loadRawResourceStyle(this, R.raw.mapstyle_night);
            break;
        case R.string.style_label_grayscale:
            // Sets the grayscale style via raw resource JSON.
            style = MapStyleOptions.loadRawResourceStyle(this, R.raw.mapstyle_grayscale);
            break;
        case R.string.style_label_no_pois_no_transit:
            // Sets the no POIs or transit style via JSON string.
            style = new MapStyleOptions("[" +
                    "  {" +
                    "    "featureType":"poi.business"," +
                    "    "elementType":"all"," +
                    "    "stylers":[" +
                    "      {" +
                    "        "visibility":"off"" +
                    "      }" +
                    "    ]" +
                    "  }," +
                    "  {" +
                    "    "featureType":"transit"," +
                    "    "elementType":"all"," +
                    "    "stylers":[" +
                    "      {" +
                    "        "visibility":"off"" +
                    "      }" +
                    "    ]" +
                    "  }" +
                    "]");
            break;
        case R.string.style_label_default:
            // Removes previously set style, by setting it to null.
            style = null;
            break;
        default:
            return;
    }
    mMap.setMapStyle(style);

在Xamarin Android中可以做到这一点吗？

随着 Xamarin google play 地图服务 v 32.961.0 https://www.nuget.org/packages/Xamarin.GooglePlayServices.Maps/的发布，现在支持 MapStyleOptions。

使用带样式的地图创建新的 MapStyleOptions 对象

private void setSelectedStyle()
    {
        MapStyleOptions style;
        style = new MapStyleOptions("[" +
                    "  {" +
                    "    "elementType":"geometry"," +
                    "    "stylers":[" +
                    "      {" +
                    "        "color":"#242f3e"" +
                    "      }" +
                    "    ]" +
                    "  }," +
                    "  {" +
                    "    "featureType":"transit"," +
                    "    "elementType":"geometry"," +
                    "    "stylers":[" +
                    "      {" +
                    "        "color":"#2f3948"" +
                    "      }" +
                    "    ]" +
                    "  }" +
                    "]");
        map.SetMapStyle(style);
    }

然后在 OnMapReady 中调用它
