Selector Expandable List View - Api 8+

I'm trying to add a selector to my expandable listview I have a background, text color and and image that I need to change state when the item is selected here's my layout for the

Solution 1:

Setting up the adapter

        ArrayList<MenuRow> menu = new ArrayList<MenuRow>();
    menu.add(new MenuChild(MenuPosition.DASHBOARD, getString(R.string.dashboard)));
    menu.add(new MenuChild(MenuPosition.HISTORY, getString(R.string.history)));
    MenuGroup group= new MenuGroup(MenuPosition.MY_GROUP,
            getString(R.string.my_group));
    group.items.add(new MenuChild(MenuPosition.CHILD_ITEM,
            getString(R.string.child_item)));
    group.items.add(new MenuChild(MenuPosition.CHILD_ITEM_2,
            getString(R.string.child_item2)));
    menu.add(group);
    menu.add(new MenuChild(MenuPosition.SETTINGS, getString(R.string.settings)));

    adapter = new MenuAdapter(context, menu);
    myExpandableListView.setAdapter(adapter);

The adapter

publicclassMenuAdapterextendsBaseExpandableListAdapter {

    private Context context;
    private ArrayList<MenuRow> menu;

MenuPosition Enum

publicenumMenuPosition {
    DASHBOARD(0, -1), HISTORY(1, -1), SETTINGS(2, -1);

    privatefinalint childPosition;
    privatefinalint groupPosition;

    MenuPosition(int groupPosition, int childPosition) {
        this.groupPosition = groupPosition;
        this.childPosition = childPosition;
    }

    publicintgetGroupIndex(){
        return groupPosition;
    }

    publicintgetChildIndex(){
        return childPosition;
    }

}

The getIconStates and getTextStates are for if you want to add other states than just selected/unselected, in my case I wanted to add state_pressed

I tried using a ColorStateList but with no avail so I used this workaround

selector_menu_item_txt

<?xml version="1.0" encoding="utf-8"?><selectorxmlns:android="http://schemas.android.com/apk/res/android"><itemandroid:state_pressed="true"android:color="@color/turquoise"/><itemandroid:color="@color/blue_grey"/></selector>

selector_menu_item_txt_selected

<?xml version="1.0" encoding="utf-8"?><selectorxmlns:android="http://schemas.android.com/apk/res/android"><itemandroid:color="@color/turquoise"/></selector>
