Are 'dividerHorizontal' and 'horizontalDivider' same? (Android)

Question

Are horizontalDivider and dividerHorizontal same?

Android Developers:

horizontalDivider:

Default horizontal divider between rows of menu items.

dividerHorizontal:

Drawable to use for generic horizontal dividers.

I'm going to use it in a LinearLayout:

<LinearLayout
    ...
    android:divider="?android:(dividerHorizontal or horizontalDivider)"
    ...>
</LinearLayout>

Which is better? Is there any difference in the design or how they're used? Or how they're referenced in (Java) code?
