android: custom dial screen
<p>i want to develop a screen that is similar to default dial screen.
and want to override the functionality for the call button.
Can you suggest the best method to implement this?</p>

<p>Can I use the andorid's dial screen and override the call button functionality or need to develop the entire view too?</p>

<p>If we need to develope the screen from the scratch, what layout is best suited for this..(gridview/tablelayout)?</p>

<p>Thanks in advance.</p>
