Question

我正在使用离子3基于位置的工作。我无法在这里获得纬度和经度的当前位置。我提到了我可用的代码。它在浏览器级别上运行良好，但在移动设备中无法正常工作。

码

$ ionic cordova plugin add cordova-plugin-geolocation --variable GEOLOCATION_USAGE_DESCRIPTION="To locate you"
$ npm install --save @ionic-native/geolocation

import { Geolocation } from '@ionic-native/geolocation';

constructor(private geolocation: Geolocation) {}

this.geolocation.getCurrentPosition().then((resp) => {
  console.log( resp.coords.latitude)
 console.log( resp.coords.longitude)
}).catch((error) => {
  console.log('Error getting location', error);
});

Answer 1

试试这个：

import { Geolocation } from '@ionic-native/geolocation';
import { Platform } from 'ionic-angular';

//Set the properties in this class
long: any; //longitude
lati: any; //latitude

constructor(private platform: Platform, private geolocation: Geolocation) {
this.platform.ready().then(()=>{

//set options.. 
var options = {
           timeout: 20000 //sorry I use this much milliseconds
       }
//use the geolocation 
this.geolocation.getCurrentPosition(options).then(data=>{
  this.long = data.coords.longitude;
  this.lati = data.coords.latitude;
 }).catch((err)=>{
     console.log("Error", err);
   });
});
}

让它在构造函数中。不要忘记同意位置隐私权限，同时在您的Android设备上启用位置选项（尽管这很可能）。

Answer 2

尝试在ionViewDidLoad（）或ngAfterViewInit（）方法中调用地理定位函数。

import { Geolocation } from '@ionic-native/geolocation';

constructor(private geolocation: Geolocation) {}

ngAfterViewInit(){
  this.geolocation.getCurrentPosition().then((resp) => {
    console.log( resp.coords.latitude)
    console.log( resp.coords.longitude)
  }).catch((error) => {
    console.log('Error getting location', error);
  });
}

我希望这能解决你的问题！

import { Geolocation } from '@ionic-native/geolocation';
import { Platform } from 'ionic-angular';

//Set the properties in this class
long: any; //longitude
lati: any; //latitude

constructor(private platform: Platform, private geolocation: Geolocation) {
this.platform.ready().then(()=>{

//set options.. 
var options = {
        enableHighAccuracy: true, timeout: 60000, maximumAge: 0
    };
//use the geolocation 
this.geolocation.getCurrentPosition(options).then(data=>{
  this.long = data.coords.longitude;
  this.lati = data.coords.latitude;
 }).catch((err)=>{
     console.log("Error", err);
   });

 let watch = this.geolocation.watchPosition(options);
          watch.subscribe((data) => {
            let lat_lng = data.coords.latitude+","+data.coords.longitude; 

});

});
}

地理位置不适用于设备ionic3
