如何在谷歌地图的屏幕中心设置标记

Question

I'm making an transport's app like uber or lyft with javascript. I need to get the map location through the center of the screen, where I have a marker at y = 0 and x = 0.

Like this image:

With the finger moves the screen and automatically registers the new position, since the marker is always in the center of the screen.

Anyone who can help me? Thank you very much

What you need is listen to the center_changed event of the map and take the lat-long of the center.As you said the marker will always be at the center of the map.

this.map = new google.maps.Map(this.mapElement.nativeElement);
_this = this; 
google.maps.event.addListener(this.map, 'center_changed', function () {
      _this.latLngObj = _this.map.getCenter();
     console.log('lat long object '+ _this.latLngObj);
    });
