How to remove underline below EditText indicator? [duplicate]

Question

Recently I had to change the EditText indicator color and, after doing that, a weird line started to appear below the indicator. How can I remove that? Code for what I've done is below.

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"                 xmlns:app="http://schemas.android.com/apk/res-auto"

Make background like this android:background="@null" of your editText
