java.lang.IllegalStateException: Содержимое adapter изменилось, но ListView не получил уведомление. Убедитесь, что содержимое адаптера не изменено из фонового потока, но только из потока пользовательского интерфейса. Убедитесь, что ваш адаптер звонит notifyDataSetChanged()Listiview error после обновления получить новые данные
поэтому я работаю с пользовательским списком ListView, когда вы достигаете финала списка. Я показываю нижний колонтитул и создаю слушателя для реализации Activity/Fragment, который будет использовать listView , Моя проблема в том, что когда я вызываю службы этого метода и обновляю массив данными адаптера, я получил эту ошибку. Я называю слишком услуги на адаптере, потому что мне нужны данные конкретной строки.
Вот отхожу код:
Пользовательские ListView:
public class EndlessListView extends ListView implements OnScrollListener {
private View footer;
private boolean isLoading;
private EndlessListener listener;
private ArrayAdapter<?> adapter;
private boolean isReachEnd;

this.setOnScrollListener(this);

public EndlessListView(Context context, AttributeSet attrs) {
super(context, attrs);

}
public EndlessListView(Context context) {
super(context);
this.setOnScrollListener(this);
}
public void refreshList() {
this.removeFooterView(footer);
this.requestLayout();
adapter.notifyDataSetChanged();
isLoading = false;
}
public void setListener(EndlessListener listener) {
this.listener = listener;
}
@Override
public void onScroll(AbsListView view, int firstVisibleItem,
int visibleItemCount, int totalItemCount) {
if (getAdapter() == null)
return;
if (getAdapter().getCount() == 0)
return;
int l = visibleItemCount + firstVisibleItem;
if (l >= totalItemCount && !isLoading && !isReachEnd) {
// It is time to add new data. We call the listener
this.addFooterView(footer);
this.requestLayout();
isLoading = true;
listener.loadData();
}
}
@Override
public void onScrollStateChanged(AbsListView view, int scrollState) {
}
public void setLoadingView(int resId) {
LayoutInflater inflater = (LayoutInflater) super.getContext().getSystemService(Context.LAYOUT_INFLATER_SERVICE);
footer = (View) inflater.inflate(resId, null);
this.addFooterView(footer);
}
public void setAdapter(ArrayAdapter<?> adapter) {
super.setAdapter(adapter);
this.adapter = adapter;
this.removeFooterView(footer);
}
public void addNewData(ArrayList data) {
this.removeFooterView(footer);
this.requestLayout();
adapter.addAll(data);
adapter.notifyDataSetChanged();
isLoading = false;
}
public void removeFooter() {
if (adapter != null) {
this.removeFooterView(footer);

this.adapter.notifyDataSetChanged();
this.requestLayout();
}
}
public void addFooter() {
if (adapter != null) {
this.addFooterView(footer);
isLoading = true;
this.adapter.notifyDataSetChanged();
this.requestLayout();
}
}
