Autocomplete edit text filtering based on two different data columns

Question

I am following an example for doing an autocomplete in my app,the code I am following is

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    mList = retrievePeople();
    txtSearch = (AutoCompleteTextView) findViewById(R.id.txt_search);
    txtSearch.setThreshold(1);
    adapter = new PeopleAdapter(this, R.layout.activity_main, R.id.lbl_name, mList);
    txtSearch.setAdapter(adapter);
}

private List<People> retrievePeople() {
    List<People> list = new ArrayList<People>();
    list.add(new People("James", "Bond", 1));
    list.add(new People("Jason", "Bourne", 2));
    list.add(new People("Ethan", "Hunt", 3));

    return list;
}

And adapter is

public PeopleAdapter(Context context, int resource, int textViewResourceId, List<People> items) {
    super(context, resource, textViewResourceId, items);
    this.context = context;
    this.resource = resource;
    this.textViewResourceId = textViewResourceId;
    this.items = items;
    tempItems = new ArrayList<People>(items); // this makes the difference.
    suggestions = new ArrayList<People>();
}

@Override
public View getView(int position, View convertView, ViewGroup parent) {
    View view = convertView;
    if (convertView == null) {
        LayoutInflater inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
        view = inflater.inflate(R.layout.row_people, parent, false);
    }
    People people = items.get(position);
    if (people != null) {
        TextView lblName = (TextView) view.findViewById(R.id.lbl_name);
        if (lblName != null)
            lblName.setText(people.getName());
    }
    return view;
}

@Override
public Filter getFilter() {
    return nameFilter;
}

/**
 * Custom Filter implementation for custom suggestions we provide.
 */
Filter nameFilter = new Filter() {
    @Override
    public CharSequence convertResultToString(Object resultValue) {
        String str = ((People) resultValue).getFirstName();
        return str;
    }

    @Override
    protected FilterResults performFiltering(CharSequence constraint) {
        if (constraint != null) {
            suggestions.clear();
            for (People people : tempItems) {
                if (people.getFirstName().toLowerCase().contains(constraint.toString().toLowerCase())) {
                    suggestions.add(people);
                }
            }
            FilterResults filterResults = new FilterResults();
            filterResults.values = suggestions;
            filterResults.count = suggestions.size();
            return filterResults;
        } else {
            return new FilterResults();
        }
    }

    @Override
    protected void publishResults(CharSequence constraint, FilterResults results) {
        List<People> filterList = (ArrayList<People>) results.values;
        if (results != null && results.count > 0) {
            clear();
            for (People people : filterList) {
                add(people);
                notifyDataSetChanged();
            }
        }
    }
};

Here the search is happening based on first name but I want search to happen based on both first name and last name.Both First name and last name should appear in the filter Kindly help,thanks in advance.

Add one more condition while checking for name, as below

for (People people : tempItems) {
     if (people.getFirstName().toLowerCase().contains(constraint.toString().toLowerCase() 
         || people.getLastName().toLowerCase().contains(constraint.toString().toLowerCase())) {
            suggestions.add(people);
      }
}
