如何在Android中的TabLayout中使标签标题向左对齐

我似乎无法在TabLayout中将标签标题向左对齐.目前，标题居中.这是我想要的.

I can't seem to align my tab titles to the left, inside my TabLayout. At the moment, the titles are centered. Here is what I want to achieve.

这就是我目前拥有的. 我正在使用的代码如下:

And this is what I have at the moment. The code I'm using is as follows:

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