Android : Android Shape Custom Rectangle

I have this to draw a rectangle.

<?xml version="1.0" encoding="UTF-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
    android:shape="rectangle">
    <solid android:color="#00000000" />
    <stroke android:width="1dp" android:color="#ffffff" android:dashWidth="0dp" android:dashGap="0dp" />
</shape>

But I want only 2 horizontal lines on the top and on the bottom. How do we achieve that?
