android - ListView setActivated(). Same item in multiple lists -

i have 2 pane layout:

• pane a: viewpager 5 listfragments.
• pane b: when click on item in pane in of lists, setactivated(true) executed on list item view, , pane b content updates.

few additional points:

• an item in 1 list appear in of other lists.
• each item in every list comes same type of data in database.
• setactivated() executed in onlistitemclick() method of listfragment.

my question:

when clicking on item, setactivated(true) used on item highlight row being activated 1 shown in content. when user uses viewpager scroll list, item might exist in list well, , want highlight activated well.

so think best way achieve inter-fragment communication reasonably elegantly?

the cleaner way this, if these fragments belong same activity, have ui-less fragment holds list want share.
cautious, don't want view in list, data, unless keen create memory leaks. bonus, can use setretaininstance(true) on ui less fragment persist items during rotations.
