[SOLVED] How to change color of Google map in Android

How to change color of Google map in Android

Here I'm trying to changing the color of google map into black from white but not getting a good solution. I tried it to change by using a relative layout over it but it hides that part , it doesn't change color of GoogleMap.

            <fragment xmlns:android="http://schemas.android.com/apk/res/android"
                android:id="@+id/map"
                class="com.google.android.gms.maps.MapFragment"
                android:layout_width="match_parent"
                android:layout_height="100dp" />

Solution

I got a solution of it by running a Html file of Google Map in WebView by putting that html file into assets folder. And I used following code to display

<!DOCTYPE html>
<html>
<head>
<title>Panoramio Layer</title>
<meta name="viewport" content="initial-scale=1.0, user-scalable=no">
<meta charset="utf-8">
<style>
    html, body, #map-canvas {
    height: 100%;
    margin: 0px;
    padding: 0px
    }
    #panel {
    position: absolute;
    top: 5px;
    left: 50%;
    margin-left: -180px;
    z-index: 5;
    background-color: #fff;
    padding: 5px;
    border: 1px solid #999;
    }
    #photo-panel {
    background: #fff;
    padding: 5px;
    overflow-y: auto;
    overflow-x: hidden;
    width: 300px;
    max-height: 300px;
    font-size: 14px;
    font-family: Arial;
    border: 1px solid #ccc;
    box-shadow: -2px 2px 2px rgba(33, 33, 33, 0.4);
    display: none;
    }
</style>
<script src="https://maps.googleapis.com/maps/api/js?v=3.exp&sensor=false&libraries=panoramio"></script>
<script>
function initializeGmaps() {
var LatLng = {lat: 28.596979, lng: 77.326742};
var mapCanvas = document.getElementById('google-map');
var mapOptions = {
center : LatLng,
scrollwheel : false,
zoom : 14,
mapTypeId : google.maps.MapTypeId.ROADMAP,
backgroundColor: 'none',
styles : [{
stylers: [
{ invert_lightness: true },
{ hue: '#666' },
{ saturation: -100 },
{ lightness: -0 },
{ visibility: 'simplified' }
]
}]
}
var map = new google.maps.Map(mapCanvas, mapOptions);
var marker = new google.maps.Marker({
position: LatLng,
map: map,
icon: '<?=base_url();?>images/marker.png',
title: 'Advisorymandi.com Pvt. Ltd.'
});
}
google.maps.event.addDomListener(window, 'load', initializeGmaps);
