Android镜子矢量可绘制

我使用材质图标(ic_play_arrow_black_24dp)，并将其导入到vector studio中.

I use a material icon (ic_play_arrow_black_24dp), imported it with the vector studio.

现在，我希望箭头也指向另一个方向，而不创建第二个矢量.可以在xml中实现吗?

Now I want the arrow to point in the other direction as well, without creating a second vector. Is this possible in xml and how?

我在两个Floating Action Button中使用了drawable，一个用于下一个，另一个用于上一个.

I use the drawable in two Floating Action Button, one for next the other for previous.

修改 这是fab按钮的XML.我已经尝试过旋转和缩放，但是没有用

Edit here is the fab button's XML. I tried already rotation and scale, but it didn´t work

<android.support.design.widget.FloatingActionButton
    android:id="@+id/previous"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_gravity="start|bottom"
    android:layout_marginBottom="0dp"
    android:layout_marginEnd="80dp"
    android:layout_marginStart="0dp"
    android:layout_marginTop="0dp"
    android:src="@drawable/next_prev_24dp"
    app:layout_anchor="@id/next"
    app:layout_anchorGravity="left" />
