Is the android:id attribute required for all views in my layout?
<p>Is the <a href="http://developer.android.com/guide/topics/ui/declaring-layout.html#id" rel="nofollow"><code>android:id</code></a> attribute required for all views in my layout? What is the best practice?</p>

<p>I would prefer to specify IDs in the rare instances that I need it (like <code>x:Name</code> in WPF), but it seems like Android and Eclipse like to have it on everything.</p>
