private static LayoutInflater inflater=null;    

public static List<SelectedFriendsObject> selectedfriends = new ArrayList<SelectedFriendsObject>();
SelectedFriendsObject friendsObject=new SelectedFriendsObject();

public MyComposeListItemAdapter(Context context, int resource) {
    super(context, resource);
    // TODO Auto-generated constructor stub

    this.mContext = context;
    this.row = resource;
    arrayList = (ArrayList<MyComposeObject>) Woosuite_Login.composeObjectslist;
//  System.out.println("arrayList2"+arrayList.size());      
    imageLoader=new ImageLoader(context);       

}   
@Override
public Context getContext() {
    // TODO Auto-generated method stub
    return mContext;
}
@Override
public int getCount() {
    // TODO Auto-generated method stub
    return arrayList.size();
}
@Override
public View getView(final int position, View convertView, ViewGroup parent) {
    // TODO Auto-generated method stub
    ViewHolder holder;

    if (convertView == null) {
        LayoutInflater inflater = (LayoutInflater) mContext
                .getSystemService(Activity.LAYOUT_INFLATER_SERVICE);
        convertView = inflater.inflate(row, null);
        holder = new ViewHolder();
        convertView.setTag(holder);
    } else
        holder = (ViewHolder) convertView.getTag();

    holder.checkBox=(CheckBox) convertView.findViewById(R.id.checkBox666);

        holder.checkBox.setOnCheckedChangeListener(new OnCheckedChangeListener() {

            @Override
            public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
                // TODO Auto-generated method stub

                if(isChecked){                                                                  
                    itemChecked.set(position, true);

                        friendsObject.setProfile_type(arrayList.get(position).getCom_profileType());
                        friendsObject.setSelected_id(arrayList.get(position).getCom_profileId());
                        selectedfriends.add(friendsObject);

                }else{

                    // when ever control comes here i need to remove the values contained in that list, 

                }
            }
        });     

    return convertView;
}

private static class ViewHolder {
    CheckBox checkBox;
}

}

You need to remove the items from the list and then call `notifyDataSetChanged` on your adapter to refresh listview — Raghunandan, Feb 27 '14 at 11:37

In the else part of holder.checkBox.setOnCheckedChangeListener you can remove the item from the arraylist and then use.

adapterObj.notifyDataSetChanged();

can you provide some sample code,i'm little bit confuse for how to remove – Androidcuckoo Feb 27 '14 at 11:49
you can use arrayList.remove(inedx) here index is the position of that item which you want to remove, and then use adapterObj.notifyDataSetChanged(); – Amit Gupta Feb 27 '14 at 11:52
