            Drawable idNormal, Drawable idSelected, Drawable idFocused,
            Drawable idUnable) {

        StateListDrawable bg = new StateListDrawable();
        // View.PRESSED_ENABLED_STATE_SET
        bg.addState(new int[] { android.R.attr.state_selected,
                android.R.attr.state_enabled }, idSelected);
