Answer 1

Change your adapter as follows

    private class CustomListAdapter extends ArrayAdapter<CustomModel> {

    private final Context context;
    private final List<CustomModel> list;
    private TextView name, message;

    public CustomListAdapter(Context context, int resource,
            List<CustomModel> list) {
        super(context, resource, list);
        this.context = context;
        this.list = list;
    }

    @Override
    public View getView(int position, View convertView, ViewGroup parent) {
        LayoutInflater inflater = (LayoutInflater) context
                .getSystemService(Context.LAYOUT_INFLATER_SERVICE);
        View view = inflater.inflate(R.layout.single_row, parent, false);

        name = (TextView) view.findViewById(R.id.name);
        message = (TextView) view.findViewById(R.id.message);
        CustomModel obj = list.get(position);

        name.setText(obj.getName());
        message.setText(obj.getMessage());

        return view;
    }

    public void updateList(List<CustomModel> list) {

        this.list = list;
        notifyDataSetChanged();

    }
}

so add the method updateList in your adapter itself and call the method notifyDataSetChanged();

so from your activity instead of calling notifyDataSetChanged(); call updateList(List<CustomModel> newList)

I am sure this will work.
