        For list items that contain secondary actions (in this case, 'delete'),
       
       
        19
       
       
        it's important to use dividers to distinguish the primary touch target from
       
       
        20
       
       
        the secondary action. This is done using android:showDividers and its
       
       
        21
       
       
        related attributes.
       
       
        22
       
       
       
       
        23
       
       
        The android:dividerPadding attribute insets the divider line by the given
       
       
        24
       
       
        amount on each side (in this case, top and bottom). Divider padding helps
       
       
        25
       
       
        establish visual hierarchy when several dividers are used in a screen. In
       
       
        26
       
       
        this case, the padding helps separate this vertical divider from horizontal
       
       
        27
       
       
        list item separators in the main ListView, and establishes a stronger
       
       
        28
       
       
        relationship between the delete action and the primary target to its left.
