 <android.support.design.widget.TabLayout
    android:id="@+id/tabs"
    app:tabGravity="fill"
    app:tabMode="fixed"
    android:background="@color/material_blue_grey_800"
    app:tabIndicatorColor="@color/orange"
    app:tabSelectedTextColor="@color/orange"
    app:tabTextColor="@color/white"
    android:layout_width="match_parent"
    android:layout_height="wrap_content">
</android.support.design.widget.TabLayout>
