Create a new resource file and add this.

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android">
    <solid android:color="@color/white" />
    <stroke android:width="1dp" android:color="@color/color_primary" />
    <corners android:radius="4dp" />
</shape>

Then set it as popupBackground
