My intention was to change item_chooser_row_background[1] to state_selected as
well but I ran into some problems and I couldn't get it to work.

1. Calling setSelected() and using state_selected resulted in the row no longer
changing color even though getDrawableState() returned state_selected.
2. I was hoping that by calling setSelected() on the parent view the children
would also be marked as selected. They did get marked as selected as seen by
getDrawableState() but they didn't change color.

(╯°□°）╯︵ ┻━┻

In the end I opted for setting isSelected() manually on the children of the row
view and keeping the item_chooser_row_background with state_activated.

   <item android:color="@color/primary_text_disabled_material_light" android:state_enabled="false"/>
   <item android:color="@color/default_text_color"/>
