Android - Error inflating class fragment

Question

I have an activity managing a list of fragments. A new fragment I added is extending ListFragmet instead of Fragment, and I added it in the activity xml layout file as the other fragments. I'm getting an InflatingException from at this file at the row where I declare the ListFragment. What is wrong with this declaration?

Activity XML

<?xml version="1.0" encoding="utf-8"?>

FavoritesFragment OnCreateView code

@Override

Answer 1

You are calling getListView() in onCreateView(). The problem is that the ListView is created in onCreateView(), so until you return from onCreateView(), the superclass does not have the ListView yet.

I would recommend that you move your onCreateView() code to onActivityCreated(), by which time the ListView will have been created. Also, you can get rid of that view local variable, as you are not using it. And, if FavoritesFragment is a ListFragment, instead of calling setOnItemClickListener(), override onListItemClick() in your fragment.
