How to change color of Google map in Android

Question

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" />

Answer 1

Go here: https://mapstyle.withgoogle.com/
Find your style and get json for your style value and copy.
Come to your android map project resource, click-new file, add json and paste style json value like style_map.json and your map activity's onMapReady(GoogleMap googleMap) do this:

mGoogleMap = googleMap;
MapStyleOptions mapStyleOptions = MapStyleOptions.loadRawResourceStyle(this, R.raw.style_json);
mGoogleMap.setMapStyle(mapStyleOptions);

It works for me :)
