Привет, я пытаюсь сделать приложение, которое вытащит список зарегистрированных пользователей друзей из facebook в мое приложение. Я использую SDK для facebook, код компилируется и, кажется, работает, но висит на счетчике анимация, когда я выбираю параметр «получить друзей» в меню! Вот код, я использую нижеAndroid-проект wont pull facebook events

есть также два других классов, которые работают с применением кода для них ниже, также
/** * ListView Друзья ArrayAdapter */ Публичный класс Друг sArrayAdapter расширяет ArrayAdapter { частный конечный контекст активности; частные конечные друзья ArrayList; private int resourceId;
/**

*/
public FriendsArrayAdapter(
Activity context,
int resourceId,
ArrayList<Friend> friends) {
super(context, resourceId, friends);
this.context = context;
this.friends = friends;
this.resourceId = resourceId;
}
/**
* Updates the view
* @param position the ArrayList position to update
* @param convertView the view to update/inflate if needed
* @param parent the groups parent view
*/
@Override
public View getView(int position, View convertView, ViewGroup parent) {
View rowView = convertView;
if (rowView == null) {
LayoutInflater vi = (LayoutInflater)context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
rowView = vi.inflate(resourceId, null);
}
Friend f = friends.get(position);
TextView rowTxt = (TextView) rowView.findViewById(R.id.rowtext_top);
rowTxt.setText(f.name);
return rowView;
}
}
public class Friend {
public String id;

любая помощь будет большим: D
Пожалуйста, разместите действительно необходимые фрагменты кода. – CSchulz
