query about View.OnClickListener() in android
<p>I'm trying to understand what is <code>View.OnClickListener()</code>.<br />
I have read this site: <a href="http://developer.android.com/reference/android/view/View.html" rel="nofollow">http://developer.android.com/reference/android/view/View.html</a>, but I cannot understand who is the client and who is the listener.</p>

<p>Please explain in details. Thanks in advance.</p>
