Turn on GPS function webview

风格不统一 提交于 2021-02-07 08:08:17
问题 I've got a webView for my website that needs to access the user location, and it does that by pressing a button and displaying the position in a form. I need a way from the webView to ask the user to turn on the gps if it's off when clicking on the button (it has id="locate button" ). How can I do that from Android studio? My code: MainActivity.java public class MainActivity extends AppCompatActivity { private WebView webview; @Override protected void onCreate(Bundle savedInstanceState) {

问题 Is it possible with javascript to generate random latitude and longitude based on the user current position? I want to generate some random latitude and longitude positions after that the user is geolocated to place some markers on a leaflet map. 回答1: Yes you can, Code below: var latBounds = [-122, -77]; var lngBounds = [30, 50]; var features = []; for( var i=0; i<80000; i++ ){ var lat = Math.random() * (latBounds[1]- latBounds[0] + 1) + latBounds[0]; var lng = Math.random() * (lngBounds[1]-

Returning Values from a geolocation API

坚强是说给别人听的谎言 提交于 2021-01-29 13:09:30
问题 I am trying to return the longitude and latitude of the user from the geolocation api but so far i keep getting errors when i try to use them outside the function. I have tried using the values within the function and they work but i cannot seem to get them to work outside the position function. I need a way to make the "location" object accessible to other functions. window.navigator.geolocation.getCurrentPosition( position => { const location = { lat:position.coords.latitude, long:position

Google map API - Search by Postcode

感情迁移 提交于 2021-01-29 07:11:59
问题 I am using Google Map Javascript API and it is working fine. var geocoder = new google.maps.Geocoder(); geocoder.geocode({ 'address': address }, function (results, status) { if (status == 'OK') { map.setCenter(results[0].geometry.location); The only issue is I cannot search by only Postcode. For example in Australia if I only search by 2000 (address = 2000) which is Sydney postcode, it doesn't return any results but if I go to the Google map page and type 2000, it shows the correct area. I

Create a clickable map preview using MKMapSnapshotter

问题 I have a map that currently shows the user's current location with no pin to show them exactly where they are. I want to make the map a photo of where the user's set location is. I only know how to show where their device is and need them to be able to set their base of operations. I don't need specific addresses. I just need the city where they reside. I then need the image to be able to be tapped on. When tapped, the image makes the MapKit full screen and interactive. They can then zoom

QML map zoom only verticaly

问题 Does map in Qt have a property, so it doesn't move center if I move mouse cursor on random place on map and try to change zoom level with mouse wheel? Because on default, map zooms, but moves existing center towards mouse cursor location (example on picture below; if cursor is on shown position and we try to change zoom, geotag picture will move in arrow direction). I just need it to zoom straight up from designated center of map, regardless of mouse cursor location. Map description: https:/

Geopy too slow - timeout all the time

拈花ヽ惹草 提交于 2021-01-28 08:07:33
问题 I am using geopy to get latitude - longitude pairs for city names. For single queries, this works fine. What I try to do now is iterating through a big list of city names (46.000) and getting geocodes for each city. Afterwards, I run them through a check loop which sorts the city (if it is in the US) in the correct state. My problem is, that I get "GeocoderTimedOut('Service timed out')" all the time, everything is pretty slow and I'm not sure if that is my fault or just geopys nature. Here is
