Suitable layout for grid of buttons in android
<p>I am confused with the appropriate layout design to be used for grid of buttons. I want to display a "textview and EditText" at the top. Below that there should be a 3*4 grid/matrix of 12 buttons(like cell phone keys), following another three linear buttons at the bottom of the root layout. (upper layout should not overlap the bottom buttons).</p>

<p>It would be of great help if anybody guide me in this regard.</p>
