Android ListItem selector

I have implemented CAB and MultiChoiceModeListener on ListView and everything works perfect except changing background color of the list item when selected (multi selection). Here is my code:

listView.xml:

<ListView 
    android:id="@+id/listView"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:divider="#ebebeb"
    android:dividerHeight="1dip"
    android:listSelector="@drawable/list_selector"/>

list_selector:

<selector xmlns:android="http://ift.tt/nIICcg">
<item android:state_selected="true" android:drawable="@android:color/holo_green_light"/>
<item android:state_pressed="true" android:drawable="@android:color/holo_blue_light"/>
<item android:state_focused="true" android:drawable="@android:color/holo_blue_dark"/>
<item android:drawable="@android:color/white"/>
</selector>

Fragment:

l.setChoiceMode(ListView.CHOICE_MODE_MULTIPLE_MODAL);
l.setMultiChoiceModeListener(new AbsListView.MultiChoiceModeListener() {
        @Override
        public void onItemCheckedStateChanged(android.view.ActionMode mode, int position, long id, boolean checked) {
            int checkedCount = l.getCheckedItemCount();
            mode.setTitle(checkedCount + " Selected");
        }

        @Override
        public boolean onCreateActionMode(android.view.ActionMode mode, Menu menu) {
            return true;
        }

        @Override
        public boolean onPrepareActionMode(android.view.ActionMode mode, Menu menu) {
            return false;
        }

        @Override
        public boolean onActionItemClicked(android.view.ActionMode mode, MenuItem item) {
        }

        @Override
        public void onDestroyActionMode(android.view.ActionMode mode) {
        }
    });
