@ape wrote an answer here on how to intercept the map clicks, but I need to intercept the touches, and then he suggested the following link in a comment of its answer, How to handle onTouch event for map in Google Map API v2?. That solution seems to be a possible workaround, but the suggested … Read more
To open url with custom label ios/android: const scheme = Platform.select({ ios: ‘maps:0,0?q=’, android: ‘geo:0,0?q=’ }); const latLng = `${lat},${lng}`; const label=”Custom Label”; const url = Platform.select({ ios: `${scheme}${label}@${latLng}`, android: `${scheme}${latLng}(${label})` }); Linking.openURL(url);
Assuming you want to preserve the elements in mapA, and merge elements in mapB for which there is no key in mapA: mapA.insert(mapB.begin(), mapB.end()) will do what you want, I think. (EDIT: If you are using C++17 or newer, consider this answer: https://stackoverflow.com/a/56594603/118150) Working example: #include <iostream> #include <map> void printIt(std::map<int,int> m) { for(std::map<int,int>::iterator it=m.begin();it!=m.end();++it) … Read more
Well any Javascript object functions sort-of like a “map” randomObject[‘hello’] = ‘world’; Typically people build simple objects for the purpose: var myMap = {}; // … myMap[newKey] = newValue; edit — well the problem with having an explicit “put” function is that you’d then have to go to pains to avoid having the function itself … Read more
Location loc1 = new Location(“”); loc1.setLatitude(lat1); loc1.setLongitude(lon1); Location loc2 = new Location(“”); loc2.setLatitude(lat2); loc2.setLongitude(lon2); float distanceInMeters = loc1.distanceTo(loc2); Reference: http://developer.android.com/reference/android/location/Location.html#distanceTo(android.location.Location)

You need to use some JavaScript stuff to show your map. OpenLayers is the number one choice for this. There is an example at http://wiki.openstreetmap.org/wiki/OpenLayers_Simple_Example and something more advanced at http://wiki.openstreetmap.org/wiki/OpenLayers_Marker and http://wiki.openstreetmap.org/wiki/Openlayers_POI_layer_example
The Go library has already got you covered. Do this: import “reflect” // m1 and m2 are the maps we want to compare eq := reflect.DeepEqual(m1, m2) if eq { fmt.Println(“They’re equal.”) } else { fmt.Println(“They’re unequal.”) } If you look at the source code for reflect.DeepEqual‘s Map case, you’ll see that it first checks … Read more
std::map‘s operator [] is not declared as const, and cannot be due to its behavior: T& operator[] (const Key& key) Returns a reference to the value that is mapped to a key equivalent to key, performing insertion if such key does not already exist. As a result, your function cannot be declared const, and use … Read more
Aonepathan’s one-liner was working for me until a recent typescript update. I found Jecelyn Yeen’s post which suggests posting this snippet into your TS Definition file add file typings.d.ts to the project’s root folder with below content declare module “*.json” { const value: any; export default value; } and then import your data like this: … Read more
