我试图获得用户的位置（纬度和经度）但由于某种原因它不起作用 . 它适用于浏览器，但不适用于手机或模拟器 . 这是我的代码 .

constructor(public navCtrl: NavController, public _http:Http, public alertCtrl:AlertController, public zone:NgZone, public platform:Platform, public loadingCtrl:LoadingController){        
  this.platform.ready().then(() => {
    if(navigator.geolocation){
        console.log('Condition is true');
        Geolocation.getCurrentPosition().then((position) => {
          console.log(position);
          }, (err) => {
            console.error(err);
          });
    }else{
      console.error("Navigator is unavailable");
    }
});}

在控制台中我得到 Condition is true 但是's the only console log I' m什么也没得到 .

    我做了下面的代码，你可以在我的github中找到一个例子https://github.com/prolland006/ionic2-geoloc/blob/master/src/services/background-geolocation-service.ts

    Geolocation.getCurrentPosition(this.foreGroundOptions)
        .then((position: Geoposition) => {
            this.trace.info(`Foregrnd current ${position.coords.latitude},${position.coords.longitude}`);
        }).catch((error)=>{
            if ((error.code == undefined) || (error.code != 3)) { //3=timeout
                this.trace.error('BackgroundGeolocationService', 'refreshLocations', `error Foregrnd.getCurrentPos:${error.toString()}`);
            }
        });

    也许你忘了选项

    // Foreground Tracking
foreGroundOptions = {
    frequency: 2000,
    enableHighAccuracy: true,
    maximumAge: Infinity,
    timeout: 2000
};

    尝试这个代码它适合我 .

    var posOptions = {timeout: 5000, enableHighAccuracy: true};
$cordovaGeolocation.getCurrentPosition(posOptions).then(function (position) {
  var fromlat = position.coords.latitude;
  var fromlng = position.coords.longitude;
  var latlng = new google.maps.LatLng(fromlat, fromlng);
  var geocoder = new google.maps.Geocoder();
  geocoder.geocode({'latLng': latlng}, function (results, status) {
    if (status == google.maps.GeocoderStatus.OK) {
      console.log(results);
    }
  });
}, function (err) {
});

    这就是我使用的 .

    import {Geolocation} from 'ionic-native';

export class someThing {
   data: any;

constructor(public navCtrl: NavController, public alertCtrl: AlertController) {
    Geolocation.getCurrentPosition().then((resp) => {
        let lat = resp.coords.latitude;
        let lng = resp.coords.longitude;
        this.data.lat = lat;
        this.data.lng = lng;
    });
}

    你能发布index.html文件和config.xml吗？

    按照步骤：

    • 离子运行android

    • 关闭GPS

    • 打开GPS

    • 关闭应用程序

    • 打开应用程序

    这是因为应用程序处于调试模式，并且与应用程序使用GPS的权限相关
