Question

我使用自定义适配器来显示列表项，这些列表项在标题下方的每个列表项中都有一个图像，一个标题和N个单独的字符串。

如何在每个列表项的com.google.android.flexbox.FlexboxLayout内使用城市标题实现N个TextView？ N量的TextView来自ArrayList<City>

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

谢谢！

适配器：

    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
    }
}

PersonAdapter的XML布局（R.layout.list_explore_people_row）

Answer 1

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

我目前不在我的主电脑附近，所以我实际上无法检查它，但这个想法大致是这个。有关详细信息，请参阅：Android dynamically add views
