我想让android后退按钮得到一个回退,并删除掉落的标记有没有任何可能的方式来做到这一点?如何移除丢弃的地图标记?
public AddMarker(){
let image = '/assets/img/rsz_marker.png';
let marker = new google.maps.Marker({
map: this.map,
animation: google.maps.Animation.DROP,
position: this.map.getCenter()
, icon: image
});
}
platform.registerBackButtonAction(() => {
if (this.nav.canGoBack()) {
this.nav.pop();
} else {
//*remove marker?
}
});
