May I store View objects in instance fields?
<p>I've got an Activity class. It sould be really nice to find all the views I need in <code>onCreate</code>, and then just reference these fields, without calling <code>findViewById</code>. But is it OK to do so?</p>

<p>Can't views be assigned different objects at runtime? E.g., is it always true that <code>findBiewById(res1) == findBiewById(res1)</code> at any time?</p>
