Button height dynamic
<p>I want to create my button height using drawable xml file and it should also resize dynamically with my layout, so that it can support any Android device.</p>

<p>Currently I am using RelativeLayout with match_parent height. I want to put a set of 3X4 buttons in this layout and should automatically resize with the device height.</p>

<p>I am not able to resize it properly when I use dp values. If I resize the button for large res device, it is not working fine for 240X320 res device.</p>
