Can't change line color of LineTextView

[rostopira]

Here is my XML:

<?xml version="1.0" encoding="utf-8"?>
<com.hanks.htextview.line.LineTextView
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:textSize="18sp"
    android:padding="12dp"
    android:gravity="center"
    app:lineColor="@android:color/white"
    app:lineWidth="4dp"
    app:animationDuration="2000"/>

Line color appears black
