keep track of parent class from member imageview
<p>I have Class A with an instance variable ImageView.  Currently I use setTag() to get from the ImageView back to the instance of Class A.  Could that present circular loop? I also heard of mention of weak references.  What is the best way to get at the parent Class A of the ImageView?  </p>

<p>My usage scenario is I am dragging the ImageView around the screen and I need to access class A for information about the ImageView being dragged.</p>
