将文本视图从 ArrayList 动态添加到自定义适配器

Question

I use a custom adapter to show list items which have an image, a title and an N amount of individual strings within each list item beneath the title.

How do I implement N amount of TextViews with the city title within the com.google.android.flexbox.FlexboxLayout of each list item? The N amount of TextViews comes from ArrayList<City>

public City (String city, int id) {
        this.city = city;
        this.id = id; 
}

Thanks!

Adapter:

    public class PersonAdapter extends ArrayAdapter<Person> {

    private ArrayList<City> cities;

    public PersonAdapter(Context context, ArrayList<Person> persons) {
        super(context, 0, persons);
    }

    @Override
    public View getView(int position, View convertView, ViewGroup parent) {
        // Hole Daten für diese Position
        Person person = getItem(position);

        cities = person.getCities();

        if (convertView == null) {

            convertView = LayoutInflater.from(getContext())
    .inflate(R.layout.list_explore_people_row, parent, false);
        }

        TextView personName = (TextView) convertView.findViewById(R.id.listItemExplorePeopleName);
        ImageView profileImg = (ImageView) convertView.findViewById(R.id.listItemExplorePeopleImg);
        TextView profileCity = (TextView) convertView.findViewById(R.id.listItemExplorePeopleCityItem);

        personName.setText(person.getName());
        profileCity.setText(person.getCities().toString()); //This is my best progress currently
        profileImg.setImageBitmap(getBitmap(getContext(), person.getProfileImg()));

        return convertView;
    }

    public Bitmap getBitmap(Context ctx, String profileFilename) {
    ...code of getBitmap for image
    }
}

Answer 1

for(City city : cities) {
    TextView textView = new TextView(this);
    textView.setText(person.getCities().toString());
    convertView.addView(textView);
}

I'm not currently near my main PC, so I can't actually check it, but the idea is roughly this. For more check this: Android dynamically add views
