Can we Manipulate the Xml layout in our Java code . I mean Lets say i have a layout in Xml and a want to create its object and change its properties (say adding some child before passing it to setcontentveiw() method)

public class IconExtensionLayoutActivity extends Activity {

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    RelativeLayout mcontainer = (RelativeLayout)IconExtensionLayoutActivity.this.findViewById(R.id.mContainerIconExtension);
    ScrollView mScrollView = (ScrollView)IconExtensionLayoutActivity.this.findViewById(R.id.mRootIconExtension);
    RelativeLayout mRow1 = (RelativeLayout)IconExtensionLayoutActivity.this.findViewById(R.id.Root_Layout_Iconset_One_ID);
    RelativeLayout mRow2 = (RelativeLayout)IconExtensionLayoutActivity.this.findViewById(R.id.Root_Layout_Iconset_Two_ID);
    RelativeLayout mRow3 = (RelativeLayout)IconExtensionLayoutActivity.this.findViewById(R.id.Root_Layout_Iconset_Three_ID);

    setContentView(mScrollView.getId());

}

}

Yes you can you have to inflate the UI of xml using LayoutInflater and then you can get the UI elements from xml. Having access to UI objects you can add extra layer of UI elements on to them and finally set them to setContentView()

LayoutInflater mInflater = LayoutInflater.from(this);  
View contentView = mInflater.inflate(R.layout.main, null); 
LinearLayout root = (LinearLayout) contentView.findViewById(R.id.root);// mContainerIconExtension in your case
root.addView(new TextView(this));
setContentView(root);
