I want this:

I have this:

I tried using elevation attribute but to no avail.

Answer 1

Elevation works on views for lollipop and plus (API 21). For achieving a divider like this you can simply add a view below your layout with grey color as background.For ex:-

<View
        android:layout_width="match_parent"
        android:layout_height="1dp"
        android:background="@color/grey"/>

Answer 2

This can not work correctly on different screens: android:layout_height="1dp" I recomended to use 1xp instead
