eclipse ADT graphical Layout

Question

I am trying to view my android xml file layout design-view but it is not displaying,I did some designing in XML with eclipse and ADT,

When I click on Graphical Layout it does not display anything and says 'Missing Theme',I also tried : Right click XML file>openwith>android layout editor but to no avail.
My development environment is:

Eclipse Helios Service Release 2,
Android Development Toolkit Version: 12.0.0.v201106281929-138431,
Dalvik Debug Monitor Service Version: 12.0.0.v201106281929-138431,
Traceview Version:12.0.0.v201106281929-138431.
What can be the problem` ?

My xml file as below

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout android:id="@+id/RelativeLayout01"android:layout_width="fill_parent" android:layout_height="fill_parent"
xmlns:android="http://schemas.android.com/apk/res/android">
