TabLayout set spacing or margin each tab

Been fighting this problem for a while too, found the solution on this thread : Android Design Support Library TabLayout using custom tabs layout but layout wrapping the tabs

<!-- Add the padding to tabPaddingStart and/or tabPaddingEnd -->
<android.support.design.widget.TabLayout
        android:id="@+id/tabLayout"
        android:layout_width="match_parent"
        android:layout_height="@dimen/tab_layout_height"
        app:tabPaddingStart="10dp"
        app:tabPaddingEnd="10dp">
