Question

我在Android中使用Leaflet ..我想在Leaflet中使用GeoJSON ..

宣传单官方网站saying，我可以无缝使用FeatureCollection

依靠这个，我试图在Leaflet中使用GeoJSON，但是我收到了错误..

我的错误是“未捕获的错误：无效的GeoJSON对象。在file：///android_asset/www/leaflet.js：8”

这里是我的GeoJSON

        {
            "geometry": {
                "coordinates": [
                    32.25980088671844,
                    37.77719365533954
                ],
                "type": "Point"
            },
            "properties": {
                "name": "shapeId",
                "value": "235"
            },
            "type": "Feature"
        }
    ],
    "type": "FeatureCollection"
}

当我从here和here检查后，JSON没有问题。

在Android端，我正在使用此命令

 mAppView.loadUrl("javascript:send('"+tmp+"')"); //tmp is my string which is converted from json

在JavaScript方面

function send(geojsonFeature)
{
alert(geojsonFeature);

L.geoJson(geojsonFeature).addTo(map);

}

我的错误是“未捕获的错误：无效的GeoJSON对象。在file：///android_asset/www/leaflet.js：8”

，它是leaflet.js

当我尝试仅添加Feature而不是FeatureCollection时，没有错误。

例如，如果我设置tmp没有像这样的FeatureCollection，错误没有出现。

tmp = {
    "type": "Feature",
    "properties": {
        "name": "Coors Field",
        "amenity": "Baseball Stadium",
        "popupContent": "This is where the Rockies play!"
    },
    "geometry": {
        "type": "Point",
        "coordinates": [-104.99404, 39.75621]
    }
};

感谢您阅读..有什么建议吗？
