AbsListView#PerformClick is a runnable posted to handle ListView clicks, and it's possible that it won't be processed until after onDestroy(). When PerformClick#run runs, it does a number of sanity checks to make sure everything is still valid, including a call to adapter.getCount(): http://androidxref.com/2.3.6/xref/frameworks/base/core/java/android/widget/AbsListView.java#1811 Since we've called onDestroyView and set mList to null, we should also disassociate mList from its adapter to prevent these phantom events. This will make PerformClick#run bail on the 'adapter != null' check (line 1809 in the file linked above).
