It seems the elevation is ignored by seekbar? Any way to get it running? I already changed the background of the embedding view to a solid color, did not help.
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="@color/white">
<SeekBar
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:elevation="4dp" />
</RelativeLayout>
