        The ListView from sample_main.xml has a choiceMode set, meaning that when a user
       
       
        19
       
       
        selects a list item, the ListView will set the state for that item's root view
       
       
        20
       
       
        (this CheckableLinearLayout) to "checked". Note that this requires that the root view
       
       
        21
       
       
        implements the Checkable interface. Once the root view is checked, any children that
       
       
        22
       
       
        have the duplicateParentState attribute set will inherit this "checked" state.
