google maps with ionic

Question

Im trying to implement a map using google maps with Ionic. I followed the coding in this Link But all i get is a blank screen dont know where i went wrong. Please help

Answer 1

If you are using the latest version of Ionic, chances are you will experience a blank screen when you deploy for android but you will see the map when u run the solution in a web browser. To resolve you need to add a whitelist plugin, run: ionic plugin add cordova-plugin-whitelist.

Answer 2

or just replace this

google.maps.event.addDomListener(window, 'load', initialize);

for this

ionic.Platform.ready(initialize);

I changed a few things to get this to work:

You don't need an api key for google maps anymore, this is enough for the script src (see Whats the Google Maps API Key):

<script src="//maps.googleapis.com/maps/api/js?sensor=false"></script>

Replace "function initialize()" with "$scope.init()" and comment out the line where it sais:

//google.maps.event.addDomListener(window, 'load', initialize);

Also add ng-init="init()" to your html like this:

<ion-header-bar class="bar-dark" ng-init="init()">
    <h1 class="title">Map</h1>
</ion-header-bar>

I don't know why it's not working with the domListener, but the data need to be initialized before displaying them (see Google MAP API Uncaught TypeError: Cannot read property 'offsetWidth' of null). With ng-init you can achieve this.

Final controller should look like this:

.controller('MapCtrl', function($scope, $ionicLoading, $compile) {

    $scope.init = function() {
        var myLatlng = new google.maps.LatLng(43.07493,-89.381388);

        var mapOptions = {
          center: myLatlng,
          zoom: 16,
          mapTypeId: google.maps.MapTypeId.ROADMAP
        };
        var map = new google.maps.Map(document.getElementById("map"),
            mapOptions);

        //Marker + infowindow + angularjs compiled ng-click
        var contentString = "<div><a ng-click='clickTest()'>Click me!</a></div>";
        var compiled = $compile(contentString)($scope);

        var infowindow = new google.maps.InfoWindow({
          content: compiled[0]
        });

        var marker = new google.maps.Marker({
          position: myLatlng,
          map: map,
          title: 'Uluru (Ayers Rock)'
        });

        google.maps.event.addListener(marker, 'click', function() {
          infowindow.open(map,marker);
        });

        $scope.map = map;
    };

    // google.maps.event.addDomListener(window, 'load', initialize);

    $scope.centerOnMe = function() {
        if(!$scope.map) {
            return;
        }

        $scope.loading = $ionicLoading.show({
          content: 'Getting current location...',
          showBackdrop: false
        });

        navigator.geolocation.getCurrentPosition(function(pos) {
          $scope.map.setCenter(new google.maps.LatLng(pos.coords.latitude, pos.coords.longitude));
          $scope.loading.hide();
        }, function(error) {
          alert('Unable to get location: ' + error.message);
        });
    };

    $scope.clickTest = function() {
        alert('Example of infowindow with ng-click')
    };
});

Hope this helped!

Answer 4

You can use the plugin angularjs-google-maps (ngmap) done for angularjs. It works for ionic. It gives you the ability to use google map v3.

Answer 5

Check out this project on github

http://angular-ui.github.io/angular-google-maps/#!/

It uses Angular.js directives to provide APIs for a good part of the Google Maps functionality.

Answer 6

I solved this by setting a in :

<ion-content ng-controller="MapCtrl">
    <div id="map" data-tap-disabled="true"></div>
</ion-content>

and then you will have to do:

.controller('MapCtrl', function($scope, $ionicLoading) {

    google.maps.event.addDomListener(window, 'load', function() {
        var newLatlng = new google.maps.LatLng(53.5000, -113.4300);

        var mapOptions = {
            center: newLatlng,
            zoom: 15,
            mapTypeId: google.maps.MapTypeId.ROADMAP
        };

        var map = new google.maps.Map(document.getElementById("map"), mapOptions);

        navigator.geolocation.getCurrentPosition(function(pos) {
            map.setCenter(new google.maps.LatLng(pos.coords.latitude, pos.coords.longitude));
            var myLocation = new google.maps.Marker({
                position: new google.maps.LatLng(pos.coords.latitude, pos.coords.longitude),
                map: map,
                title: "My Location"
            });
        });

        $scope.map = map;
    });

});
