Android :: ListView Item Selector To Use State_checked?

Trying to get an Android ListView to do what I want.

I want to have a ListView in single choice mode with a custom row layout that has a different background color for selected, pressed and checked (i.e. the choice is shown by a color rather than a check mark - this is what I would normally call the "selection" but selection in android seems line I'm about to choose before I press it)

I thought of trying a background selector with the three states in it. It works fine for state_selected and state_pressed, but not state_checked. So I created a CheckableRelativeLayout that extends RelativeLayout and implements Checkable and used for the view of each row.

A simplified version is shown here:

CODE:.....

bkg_selector looks like

CODE:..............

The colors are defined elsewhere.

This still didn't work. So in the custom ListAdapter I tracked the "checked" row and tried (in getView) if( position == checkedPosition ) ret.getBackground().setState(CHECKED_STATE_SET);

And it STILL doesn't work. How can I get it to do what I want?
