You have to create a different state drawable for each color you want to use.
For example: list_selector_read.xml
and list_selector_unread.xml
.
All you need to do is set everything to transparent except the android:state_window_focused="false"
item.
Then when you are drawing your list you call setBackgroundResource(R.drawable.list_selector_unread/read)
for each row.
You don’t set a listSelector on the ListView at all. That will maintain the default selector for your particular flavor of Android.
