How to hide underbar in EditText

Question

How can I hide the EditText underbar (the prompt line with little serifs at the ends)?

There might be a better way to do what I want: I have a layout with an EditTe

I discovered the most curious thing! If you set it to null using Data Binding: android:background="@{null}"

Then not only is the background removed, but the view still has the padding that was calculated from the default background. So for some reason the deferred null setting doesn't clear the padding from the previous bg..? The padding on the view is left/top/right 4dp, bottom 13dp (from emulator level 21).

May not have same end result on all API levels, so beware! Someone tell me if you test this and find it reliable. (Also note that that bottom padding sticks out because of that underline that was in the original. So you'll probably want to change it in the XML, or reset it in the code after it's loaded to equal top...
