Activity.LoadLayout("Layout1")
Private cd As ColorDrawable
cd.Initialize(Colors.Transparent, 0)
EditText1.Background = cd
In The layout are two EditTexts.
In EditText1 the background is set to a transparent color drawable. The second one wasn't changed.
I used a white activity and black text. Unfortunaly i don't have the time to play with more colors and see if this causes issues.....
