Create an xml file inside your drawable folder

custom_indicator.xml

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
 <!-- UNSELECTED TAB STATE -->
<item android:state_selected="false" android:state_pressed="false">
    <layer-list xmlns:android="http://schemas.android.com/apk/res/android">
        <!-- Bottom indicator color for the UNSELECTED tab state -->
        <item android:top="-5dp" android:left="-5dp" android:right="-5dp">
            <shape android:shape="rectangle">
                <stroke android:color="#65acee" android:width="2dp"/>
            </shape>
        </item>
    </layer-list>
</item>
</selector>

And set this drawable in your tabLayout

<android.support.design.widget.TabLayout
            android:id="@+id/tab_layout"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:background="@color/white"
            app:tabGravity="fill"
            app:tabMode="fixed"
            app:tabBackground="@drawable/custom_indicator" />

To change the unselected tab text color, simple provide a default tab text color and selected tab text color as follows:

<android.support.design.widget.TabLayout
            android:id="@+id/tab_layout"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:background="@color/white"
            app:tabGravity="fill"
            app:tabMode="fixed"
            app:tabTextColor="@color/unselected_color"
            app:tabSelectedTextColor="@color/selected_color"
            app:tabBackground="@drawable/custom_indicator" />
