error 

     java.lang.nullpointerexception: attempt invoke virtual method 'void android.widget.linearlayout.addview(android.view.view)' on null object reference

thanks

try inflating layout false flag 3rd param:

 view v = inflater.inflate(r.layout.item_non_highlight, null, false);

you exception because default android tries add newly inflated view it's parent (second param) , passed there null mentioned exception.

see doc: http://developer.android.com/reference/android/view/layoutinflater.html#inflate(org.xmlpull.v1.xmlpullparser, android.view.viewgroup, boolean)
