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

        The duplicateParentState attribute on this ImageView, along with the state list
        drawable in the src attribute causes its image to change when its parent
        is checked or unchecked.

        To use the standard radio or checkmark image, set the src to
        ?android:listChoiceIndicatorMultiple or ?android:listChoiceIndicatorSingle. These
        are system theme attributes that reference a state list drawable.
