It depends how deep your EditText is, if it's single line you probably won't notice the difference. but it does work if you have a deeper EditText. EditText also has padding, so it may not display right at the bottom if that's what you are expecting.
You can adjust it using JavaObject:
Dim JO As JavaObject = editText1
JO.RunMethod("setPadding",Array As Object(0,0,0,0))
