How can I fix it? Thanks 回答1: It can't be done like this, the documentation you link to states: setCircleOptions(options:google.maps.CircleOptions) This method will ignore certain properties of the

HTML5 Geolocation - Detect location within a specific area

由 时光毁灭记忆、已成空白 提交于 2019-12-25 18:01:10

So if you've defined a function isInArea that checks a position to see if it's in your

Also why sentence "geohashGetCoordRange(&long_range, &lat_range);" is called two times? GeoHashRadius geohashGetAreasByRadius(double longitude, double latitude, double radius_meters) { GeoHashRange long_range, lat_range; GeoHashRadius radius =

问题 It's difficult to tell what is being asked here. This question is ambiguous, vague, incomplete, overly broad, or rhetorical and cannot be reasonably answered in its current form.

Then I wrote a script to read the long/lan from this adressen and store them in the DB. At this moment there are 10 items in the DB but when i add the 12th or 13th,

ReverseGeocodingTask task to a method

由 ぃ、小莉子 提交于 2019-12-25 07:28:28
