ionic 调用百度地图API，并定位当前位置示例

import { Component, ViewChild, ElementRef } from ‘@angular/core‘;

import { IonicPage, NavController, AlertController, NavParams, MenuController } from ‘ionic-angular‘;

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

declare var BMap;

declare var BMapLib;

  constructor(public navCtrl: NavController, public navParams: NavParams,

   private geolocation: Geolocation) { 

   //此处请自行放置一个icon文件到 ssets/icon目录中

    this.myIcon = new BMap.Icon("assets/icon/position.png", new BMap.Size(32, 32));

  }

 

ionViewDidLoad() {

    //Amin: !Important:map_container shoud be called here, it can‘t be inited in constructor, if called in constructor

    this.map = new BMap.Map("map_container");

    this.map.centerAndZoom(‘上海‘, 13);

    this.map.enableScrollWheelZoom(true);

    this.myGeo = new BMap.Geocoder();

    var geolocationControl = new BMap.GeolocationControl();

    this.map.addControl(geolocationControl);

    this.getLocation();

  }

 

getLocation() {

    this.geolocation.getCurrentPosition().then((resp) => {

      if (resp && resp.coords) {

        let locationPoint = new BMap.Point(resp.coords.longitude, resp.coords.latitude);

        let convertor = new BMap.Convertor();

            this.map.panTo(data.points[0]);

            marker.setPosition(data.points[0]);

            this.map.addOverlay(marker);

          }

        })

        this.map.centerAndZoom(locationPoint, 13);

        console.log(‘GPS定位：您的位置是 ‘ + resp.coords.longitude + ‘,‘ + resp.coords.latitude);

      }

    }).catch(e => {
