[android-developers] Re: ViewHolder Pattern leaking a Context on retained Fragments

As a temporary fix, you can use WeakReference to hold the references
to your views without leaking/retaining them.

This is similar to the GC-wary use of WeakReference in callbacks and
listeners: use WeakReference<YourObject> when you pass your object's
reference to another object whose lifetime may be longer than the
referenced object (YourObject).

That way, your object can be garbage collected even if some listener
or callback (or other holder) holds a weak reference to it.
