Vertical Android TabLayout not scroll vertically

问题

I try to develop left TabLayout like this image.

But the problem is TabLayout element not shows and scrolling Vertically. There is my code below maybe I missed something:

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:layout_width="match_parent"
    android:layout_height="match_parent">
    <android.support.v4.view.ViewPager
        android:id="@+id/viewpager"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_toRightOf="@+id/appBarLay"
        app:layout_behavior="@string/appbar_scrolling_view_behavior"/>
    <android.support.design.widget.AppBarLayout
        android:id="@+id/appBarLay"
        android:layout_width="wrap_content"
        android:layout_height="match_parent"
        android:layout_alignParentLeft="true"
        android:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar">
        <android.support.design.widget.TabLayout
            android:id="@+id/tabs"
            android:layout_width="60dp"
            android:layout_height="match_parent"
            app:tabBackground="@drawable/tab_color_selector"
            app:tabGravity="fill"
            app:tabMode="scrollable" />
    </android.support.design.widget.AppBarLayout>
</RelativeLayout>

As mentioned in android documentation, see this

TabLayout provides a horizontal layout to display tabs.

This means you cannot use TabLayout to display vertical tabs. However, you can use TabHost to achieve it.
