I want to be able to keep a marker constantly in the center of Google Maps on my mobile application.
I have tried using bindTo functionality of Google Maps, which binds the marker to the center of the map, but it seems a bit clumsy.
I have tried doing it using HTML and CSS also, but Google Maps does not allow it.
The same as in Uber app.

Can you please also tell me how to do this with current location displaying at the time map initializes? Thank YouAbraham Guttman– Abraham Guttman2016年06月06日 12:25:44 +00:00Commented Jun 6, 2016 at 12:25

This is a fully functional code which may satisfy your requirements:
<!DOCTYPE html>
<html>
<head>
<meta name="viewport" content="initial-scale=1.0, user-scalable=no" />
<style type="text/css">
html { height: 100% }
body { height: 100%; margin: 0; padding: 0 }
#map-canvas { height: 100% }
</style>
<script type="text/javascript"
src="https://maps.googleapis.com/maps/api/js?v=3.exp&sensor=false">
</script>
<script type="text/javascript">
function initialize() {
var myLatlng = new google.maps.LatLng(-25.363882,131.044922);
var mapOptions = {
center: myLatlng,
zoom: 8
};
var map = new google.maps.Map(document.getElementById("map-canvas"),
mapOptions);
var marker = new google.maps.Marker({
position: myLatlng,
map: map,
title: 'Hello World!'
});
google.maps.event.addListener(map, 'center_changed', function() {
// 0.1 seconds after the center of the map has changed,
// set back the marker position.
window.setTimeout(function() {
var center = map.getCenter();
marker.setPosition(center);
}, 100);
});
}
google.maps.event.addDomListener(window, 'load', initialize);
</script>
</head>
<body><div id="map-canvas"/></body></html>
