Programmatically changing underline color of EditText

Question

I have an ordinary EditText field that I would like to programmatically change the underline color for.

Answer 1

You need to set the backgroundTintList (or supportBackgroundTintList) on the EditText to an instance of ColorStateList containing only the color you wish to change the tint to. An easy way to do this in a backwards-compatible way looks like this:

ColorStateList colorStateList = ColorStateList.valueOf(color);
editText.setSupportBackgroundTintList(colorStateList);

This will give the EditText the desired underline color.
