The problem with what you are looking for is that different versions of Android and/or different devices make EditText views look different. For example, on my Archos 70 running Android 2.2, they have a shadowed, 3D effect while on my Toshiba Thrive running Android 3.1, they appear flat.
One solution for getting EditText views to look the way you want is to draw them in a graphics program and load the images into ImageViews, then put the EditTexts on top of them with the ET's Alpha set to 0 (transparent).
If you look at the first screen shot in
this post, you will see a couple of EditText views in the middle. These are actually invisible EditTexts on top of ImgViews on top of Panels. The panels are colored orange and their Alpha changed to show or hide the borders.
If you do this, you will probably need to draw images for different size/density devices or even different size views on the same device since shrinking or stretching the images may change the way they look.
