【问题描述】:
我想根据我的标记使我的地图居中。 我找到了“LatLngBounds”函数来执行此操作,但就我而言,它不起作用。
结果如下:
我们注意到缩放不够高。 我应该得到一个放大巴黎市的结果
这是我的 TS 代码:
import { Component, ViewChild, ElementRef } from '@angular/core';
import { IonicPage, NavController } from 'ionic-angular';
import { AngularFireAuth } from "angularfire2/auth";
import { GoogleMapsProvider } from './../../providers/google-maps/google-maps';
declare var google: any;
@IonicPage()
@Component({
selector: 'page-favorite',
templateUrl: 'favorite.html'
})
export class FavoritePage {
@ViewChild('map') mapRef: ElementRef;
map: any;
lat: string;
lng: string;
view: string = "list";
/**
* a MODIFIER AVEC l'API
*/
favorites: { id_place: string, name: string, photo: string, address: string }[] = [
{ "id_place": "9054b4cc53b207424db12d23e1b34b3ae0cfe9c0", "name": "Café Madeleine Paris", "photo": "https://lh3.googleusercontent.com/p/AF1QipMkeDY6tB5bQFEPhy1Ah4HR-2Oh7CjO_td-BbDY=s1600-w400", "address": "1 Rue Tronchet, Paris" },
{ "id_place": "cf49d5cbc84ecbe0388ef93eb80aa18f9db3ffa9", "name": "Cafe Kitsune", "photo": "https://lh3.googleusercontent.com/p/AF1QipNk8GqMTGNo-QF_QwdakFaNvoGwi11tHmY-969p=s1600-w400", "address": "1 Rue Tronchet, Paris" },
{ "id_place": "b8c6ecc9f9e047dd428f3994c537c3f877ba0e30", "name": "Café des Abattoirs", "photo": "https://lh3.googleusercontent.com/p/AF1QipPRKYf0L3uEYzPee5Y7uUBa15Q_7WWtUTWSHvqd=s1600-w400", "address": "10 Rue Gomboust, Paris" },
];
positions = [
['Café paris', 48.86976989999999, 2.3253528, 1],
['Café paris2', 48.8708719, 2.3317623, 2],
['Café paris 3', 48.8710058, 2.3249572, 3]
];
private bounds = new google.maps.LatLngBounds();
constructor(
private aFAuth: AngularFireAuth,
public navCtrl: NavController,
public GoogleMaps: GoogleMapsProvider,
) {
}
ionViewDidLoad() {
this.initMap();
}
initMap() {
this.map = new google.maps.Map(this.mapRef.nativeElement);
this.setMarkers(this.map);
this.map.fitBounds(this.bounds);
}
setMarkers(map) {
for (var i = 0; i < this.positions.length; i++) {
var position = this.positions[i];
var marker = new google.maps.Marker({
position: { lat: position[1], lng: position[2] },
map: map,
title: position[0],
zIndex: position[3]
});
this.bounds.extend(marker.position);
}
}
removeFavorite(id_place) {
console.log('Remove favorite : ', id_place)
}
}
请你帮帮我好吗? 谢谢!
