I'm trying to implement a cancel/done layout in my action bar using ActionBarSherlock by adapting the code found here.Everything works as intended on ICS or Jelly Bean (where ABS will use the native ActionBar). When testing on Gingerbread (API 10), everything works fine except that the divider does not appear between the buttons.I at first thought that this was an issue with the divider image, but even when using code like:android:divider="#f00"No divider appears on Gingerbread, but a bright red one appears, as expected, on ICS/JB. Apparently ActionBarSherlock 4 uses the native behaviour for divider appearance, so why is the divider not appearing when ABS is used but is appearing when the native ActionBar is used?Here's my XML:actionbar_custom_view_done_discard.xml<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent" android:layout_height="match_parent" android:divider="?attr/dividerVertical" android:dividerPadding="12dp" androidrientation="horizontal" android:showDividers="middle" > <include layout="@layout/actionbar_cancel_button" /> <include layout="@layout/actionbar_done_button" /></LinearLayout>actionbar_cancel_button.xml<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/actionbar_cancel" style="?actionButtonStyle" android:layout_width="0dp" android:layout_height="match_parent" android:layout_weight="1" android:background="@drawable/abs__item_background_holo_light" > <TextView style="?actionBarTabTextStyle" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_gravity="center" android:drawableLeft="@drawable/ic_action_cancel" android:drawablePadding="8dp" android:gravity="center_vertical" androidaddingRight="20dp" android:text="@string/action_cancel" /></FrameLayout>actionbar_done_button.xml is exactly the same as the above but with the name, text and icon changed.Thanks in advance.
