Android menu controls
<p>I am developing an application and I would like to use the control that I can see in the Photos application and the Desk Clock (on an HTC Desire).</p>

<p>The one I am referring to is the bar along the bottom of the screen that has various icons in it. When you press on an icon, the bubble moves along the bar to the icon you have pressed and the icon is then shown in colour.</p>

<p>What is the name of this control? </p>
