Android Extensible List Selector Behavior

I am having a serious problem with my selectors in the Expandable List view in Android.

Here is my code for Expandable List.

public class UserMenuAdapter extends BaseExpandableListAdapter {

    private ArrayList<String> groups;
    private ArrayList<ArrayList<ChildItems>> childs;
    private Context context;
    public LayoutInflater inflater;

    ImageView img_availabiliy;

    private static final int[] EMPTY_STATE_SET = {};
    private static final int[] GROUP_EXPANDED_STATE_SET =
            {android.R.attr.state_expanded};
    private static final int[][] GROUP_STATE_SETS = {
         EMPTY_STATE_SET, // 0
         GROUP_EXPANDED_STATE_SET // 1
    };

    public UserMenuAdapter(Context context, ArrayList<String> groups,
            ArrayList<ArrayList<ChildItems>> childs) {
        this.context = context;
        this.groups = groups;
        this.childs = childs;
        inflater = LayoutInflater.from(context);
    }

    @Override
    public Object getChild(int groupPosition, int childPosition) {
        return childs.get(groupPosition).get(childPosition);
    }

    @Override
    public long getChildId(int groupPosition, int childPosition) {
        return (long) (groupPosition * 1024 + childPosition);
    }

    @Override
    public View getChildView(int groupPosition, int childPosition,
            boolean isLastChild, View convertView, ViewGroup parent) {
        View v = null;
        if (convertView != null)
            v = convertView;
        else
            v = inflater.inflate(R.layout.child_layout, parent, false);
        ChildItems ci = (ChildItems) getChild(groupPosition, childPosition);
        TextView tv = (TextView) v.findViewById(R.id.tvChild);
        tv.setText(ci.getName());
        TextView tv2 = (TextView) v.findViewById(R.id.tvChild2);
        tv2.setText(ci.getDailyStatus());
        img_availabiliy = (ImageView)v.findViewById(R.id.img_childlayout_AVAILABILITY);
        ImageView friendPics = (ImageView)v.findViewById(R.id.ivFriendPics);

        /**For Group child*/
        if(groupPosition == 3 && childPosition!= 0){
            if(ci.getPicture()!= null){
                Bitmap bitmap = BitmapFactory.decodeByteArray(ci.getPicture(), 0, ci.getPicture().length);
                bitmap = Bitmap.createScaledBitmap(bitmap, 48, 48, true);
                friendPics.setImageBitmap(bitmap);
            }else{
                friendPics.setImageResource(R.drawable.ic_launcher);
            }
            img_availabiliy.setVisibility(View.INVISIBLE);
        }else{
            if(ci.getStatusState() == 1){
                img_availabiliy.setImageResource(R.drawable.online);

When I expand the groups, I change the color of the selector bar and vice versa.

The problem I am running into is that when I go back from any activity or strictly view the expanded view of the list, the color of the selector automatically changes even if the group is selected / not selected

If someone clicks on the top of the screen (device), then they also select the selector

I am completely confused about what he is showing me and cannot find out what is going on. Please help if anyone understands
