У меня есть java.lang.unsupportedoPerationException в Android Studio ⇐ Android

[Anonymous]

public boolean onOptionsItemSelected(MenuItem item){
int id = item.getItemId();

switch(id){
case R.id.jaren_3de:
updateKlassenList(klassen);
break;
case R.id.jaren_4de:
updateKlassenList(klassen2);
break;
case R.id.jaren_5de:
updateKlassenList(klassen3);
break;
case R.id.jaren_6de:
updateKlassenList(klassen4);
break;

// case R.id.

}

return super.onOptionsItemSelected(item);
}

private void updateKlassenList(String[] data) {
klassenList.clear();
klassenList.addAll(Arrays.asList(data));

// I assume "adapter" is the adapter of interest.
adapter.notifyDataSetChanged();
}
< /code>

Я добавил метод: < /p>

private void updateKlassenList(String[] data) {
klassenList.clear();
klassenList.addAll(Arrays.asList(data));

// I assume "adapter" is the adapter of interest.
adapter.notifyDataSetChanged();
}
< /code>

Чтобы решить предыдущую проблему (см. Как изменить список значение внутри OnoptionsItemselemed в Android Studio?), Но теперь я получаю java.lang.unsupportedoperationsexexception. Я искал это, и кажется, что это как -то связано с устаревшими версиями, но я недавно все обновил. < /P>

/>
Изменить: это ошибка, которую я получаю: < /p>
