Add event listeners to shapes in android.graphics package
<p>I am new to android programming &amp; I'm trying to create a simple program where I can handle drag &amp; touch events on different shapes.</p>

<p>From the android API, I understand that it is easy to add event listeners to widgets(eg:ImageView). But how do I do the same for graphics such as RectF or Circle?</p>

<p>Since I'm a novice, I would appreciate if someone could explain in simpler terms.</p>
