you need create new .xml file drawable folder. can call "bottom_navbar_background.xml". draw rectangle on file that:

<?xml version="1.0" encoding="utf-8"?>  <layer-list xmlns:android="http://schemas.android.com/apk/res/android">      <item android:bottom="1dp">         <shape             android:dither="true"             android:shape="rectangle">             <corners android:radius="2dp" />              <solid android:color="@color/black" />         </shape>     </item>      <item android:top="1dp">         <shape             android:dither="true"             android:shape="rectangle">               <solid android:color="@android:color/white" />              <padding                 android:bottom="0dp"                 android:left="0dp"                 android:right="0dp"                 android:top="0dp" />         </shape>     </item>  </layer-list>

put background of custom theme of splitnavbar this:

<item name="android:backgroundsplit">@drawable/bottom_navbar_background</item>

et voila: have top border on navbar!
