[英]ionic 2 dynamic markers in Google Maps with profile picture
我正在使用存儲在數據庫中的跟蹤數據構建ionic2應用程序,我能夠獲取地理位置數據並初始化地圖,但是我有一個帶有profileimageurl
和lat
lng
值的markers
數組,我試圖將標記列表放在帶有profileimageurl作為圖標的地圖,但是它不起作用
谷歌地圖初始化
initMap(): Promise<void> {
let promise: Promise<void> = new Promise<void>((resolve, reject) => {
Geolocation.getCurrentPosition().then((position) => {
let latLng = new google.maps.LatLng(position.coords.latitude, position.coords.longitude);
let GooleMap = new google.maps.Map(document.getElementById('map'), {
center: latLng,
zoom: 18
});
let marker = new google.maps.Marker({
position: latLng,
map: GooleMap,
title: 'My Location',
});
});
});
return promise;
}
標記數組
markers: marker[] = [
{
lat: 51.673858,
lng: 7.815982,
label: 'A',
profileImage: "http://www.gravatar.com/avatar/d735414fa8687e8874783702f6c96fa6?s=90&d=identicon&r=PG"
},
{
lat: 51.373858,
lng: 7.215982,
label: 'B',
profileImage: "http://placekitten.com/90/90"
}
]
我已經為此苦苦掙扎了一段時間,非常感謝您的答復,謝謝
我會重寫google.maps.OverlayView
來實現它。
class CustomMarker extends google.maps.OverlayView {
marker: any;
clickListener: google.maps.MapsEventListener;
constructor(private latlng, map, private args) {
super();
this.setMap(map);
}
draw() {
const panes = this.getPanes();
let marker = this.marker;
if (!marker) {
marker = this.marker = document.createElement('div');
marker.className = 'marker';
let img = document.createElement('img');
img.src = this.args.img;
marker.appendChild(img);
let point = this.getProjection().fromLatLngToDivPixel(this.latlng);
if (point) {
marker.style.left = (point.x - 50) + 'px';
marker.style.top = (point.y - 50) + 'px';
}
this.clickListener = google.maps.event.addDomListener(marker, "click", (event) => {
alert('You clicked on a custom marker!');
google.maps.event.trigger(this, "click");
});
panes.overlayImage.appendChild(marker);
}
}
remove() {
if (this.marker) {
this.marker.parentNode.removeChild(this.marker);
this.clickListener.remove();
this.marker = null;
}
}
getPosition() {
return this.latlng;
}
}
PS我猜你已經安裝了@types/google-maps
