android - Fragment with ListView: NullPointerException on setAdapter -

I have a problem, when I want to set the adapter on my ListView, I get a NullPointExeption before I Increased fragmentation with listfreagment and a simple adapter, before the problem was that it works but the problem is that I have 3 pieces in this activity with list activity and I found performance errors (shows the wrong list in one piece is). That's why I decided to set my own id of each piece on the list view, but now it does not work.

Error List View Ksetadaptr (adapter):

  listview = (ListView) view.findViewById (R.id.listLive);
