可以将文章内容翻译成中文,广告屏蔽插件可能会导致该功能失效(如失效，请关闭广告屏蔽插件后再试): 问题: Is it possible not only to have Google Maps on Android show a given coordinate in the Maps Application but have also a marker (or pin) set at the location? I read the documentation at https://developer.android.com/guide/appendix/g-app-intents.html but it only lets me set the zoom level. Right now I use the following code to show a place in Google Maps on Android: Double lat = 53.3; Double lng = 13.4; final String uriString = "geo:" + lat + ',' + lng + "?z=15"; Intent showOnMapIntent = new Intent(Intent.ACTION_VIEW, Uri.parse(uriString));

How can I do that using Google Maps API v3 ? Thanks 回答1: See here for details on the various options open to you but you now have to iterate through the markers and remove them individually. Your code should look something like this: var markers = []; function clearOverlays () { while ( markers . length ) { markers . pop (). setMap ( null ); } markers . length = 0 ; } markers . push ( marker ); google . maps . event . addListener (

Best way to merge two maps and sum the values of same key?

So the result will be: Map(2->20, 1->109, 3->300) Now I have 2 solutions: val list = map1.toList ++ map2.toList val merged = list.groupBy ( _._1) .map { case (k,v) => k -> v.map(_._2).sum } and val merged = (map1 /: map2) { case (map, (k,v)) => map + ( k -> (v + map.getOrElse(k, 0)) ) } But I want to know if there are any better solutions. 回答1: Scalaz has the concept of a Semigroup which captures what you want to do here

How do I use the Google Maps API GPS sensor?

可以将文章内容翻译成中文,广告屏蔽插件可能会导致该功能失效(如失效，请关闭广告屏蔽插件后再试): 问题: All I've been able to find is how to specify the sensor parameter: http://code.google.com/apis/maps/documentation/v3/#SpecifyingSensor But nowhere does it say how to actually USE it. Isn't the whole point to be able to get the user's current lat/long coordinates through the device GPS, or am I mistaken? 回答1: That sensor parameter is only there to indicate to Google that you are using a GPS sensor to determine the user's location. Unless using the W3C Geolocation API in browsers that support it, it remains your responsibility to get the

My goal is to get the user to input his/her address into the field and then when he/she clicks confirm work out the closest store to them based on the information provided. I have the lat/long for each store and with the help of autocomplete I now have the lat/long of the users address but when I use the computeDistanceBetween method provided in the documentation I get NaN instead of a desired result. Here is a link to the test site to get an idea - http://dev
