Question

我有一个Web应用程序，它显示不同位置的纬度和经度数据。我正在尝试使用通过Xamarin中的Web视图开发的android应用程序打开同一Web应用程序。但是纬度和经度显示为空白。当我使用Chrome浏览器时，效果很好。请帮我。

protected override void OnCreate(Bundle savedInstanceState)
{
    base.OnCreate(savedInstanceState);
    SetContentView(Resource.Layout.layout3);
    web_view = FindViewById<WebView>(Resource.Id.webview);
    web_view.Settings.JavaScriptEnabled = true;
    web_view.Settings.SetGeolocationEnabled(true);
    web_view.SetWebViewClient(new HelloWebViewClient());
    web_view.SetWebChromeClient(new GeoWebChromeClient());
    web_view.Settings.JavaScriptCanOpenWindowsAutomatically = true;
    web_view.Settings.DisplayZoomControls = true;
    web_view.Settings.JavaScriptEnabled = true;
    web_view.Settings.SetGeolocationEnabled(true);
    web_view.LoadUrl("https://abcd.com");
}


class GeoWebChromeClient : WebChromeClient
{
    public override void OnGeolocationPermissionsShowPrompt(string origin, GeolocationPermissions.ICallback callback)
    {
        callback.Invoke(origin, false, false);
    }

}



class HelloWebViewClient:WebViewClient
{
    // For API level 24 and later
    public override bool ShouldOverrideUrlLoading(WebView view, IWebResourceRequest request)
    {
        view.LoadUrl(request.Url.ToString());
        return false;
    }
}

将其添加到清单文件中。

db.collection.aggregate(
[
    {$match:{storeId:{$in:[
ObjectId("e069d1b76557685b9e235v"),ObjectId("e069d1b76557685b9t7j8n"),
ObjectId("e069d1b76557685b9e2fg6"),ObjectId("e069d1b76557685b9p56r2") 
]},
 timeStamp: {$gt: ISODate(createdAt)},
}},
{$group:{_id:"$storeId", week: { $week: '$timeStamp'}, totalPoints: {$sum: "$points"}, averagePoints: {$avg: "$points"}} },
    {$sort: {totalPoints:-1}}
])

在“活动”中添加此内容：之后，尝试获取位置值。

<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />

Xamarin Webview没有给出纬度和经度
