Can't use custom divider

[AndreaScn]

I tried to use custom divider in my xml file like:

<com.baoyz.swipemenulistview.SwipeMenuListView
        android:id="@+id/listView"
        android:layout_alignParentStart="false"
        android:layout_alignParentLeft="true"
        android:layout_alignParentTop="true"
        android:layout_width="wrap_content"
        android:layout_height="fill_parent"
        android:layout_alignWithParentIfMissing="true"
        android:layout_alignParentRight="true"
        android:layout_alignParentEnd="false"
        android:longClickable="false"
        android:layout_gravity="center"
        android:divider="@drawable/list_divider"/>

and I defined my list_divider in drawable/list_divider but it seems not working.
I also tried to change divider color and height in this way:

<com.baoyz.swipemenulistview.SwipeMenuListView
        android:id="@+id/listView"
        android:divider="@color/colorPrimaryDark"
        android:dividerHeight="2dip"
        android:layout_alignParentStart="false"
        android:layout_alignParentLeft="true"
        android:layout_alignParentTop="true"
        android:layout_width="wrap_content"
        android:layout_height="fill_parent"
        android:layout_alignWithParentIfMissing="true"
        android:layout_alignParentRight="true"
        android:layout_alignParentEnd="false"
        android:longClickable="false"
        android:layout_gravity="center" />

but both still not working.
It is strange since SwipeMenuListView extends Listview.
Any clue?

Thanks
