PermissionUtils.requestPermission(this, LOCATION_PERMISSION_REQUEST_CODE, Manifest

由 情到浓时终转凉″ 提交于 2021-02-08 08:43:38
问题 I use filters to hide or show features/markers in the Data Layer. I try to check which markers are visible after filtering, and if one property of the feature matches one property of an existing polyline (in another json file); then I decide if I show or hide the polyline also. How to know if a certain marker is visible? 回答1: You could set a custom property on the feature and toggle it as you hide and show the feature: feature.setProperty('visible', false); This would have to be done in

How to hide tooltip title in google geocharts (and show other info in the tooltip)

由 霸气de小男生 提交于 2021-02-08 04:45:26

Google Street View Maps - Parsing url to use as street image

由 泪湿孤枕 提交于 2021-02-08 04:11:07
问题 Situation: I'm working on a map feature for a client and I need the ability to get screenshots of a street view, and then display them as a carousel (similar to how Google does it natively). They can choose whatever locations they want in their CMS. The only way I can think of to do this (taking into account non-tech end users) is to allow them to copy and paste the URL from a street view, and then parse it out. For example: https://www.google.com/maps/@60.959789,-149.112111,3a,75y,104.14h,94

Custom Google Maps marker info view on Xamarin.iOS

由 半世苍凉 提交于 2021-02-08 03:43:16
问题 The IMapViewDelegate apparently isn't a complete C# implementation of MapViewDelegate from objC. That inhibits the access to markerInfoContents delegate method.
