Question

我有一个自定义对象的ArrayList，电影将提供有关它们的所有信息。我收到了所有信息，并对其进行了某种排序。然后，它用ReyclerView填充了所有内容。此错误并非始终发生，但有时会出现此错误：

E/AndroidRuntime: FATAL EXCEPTION: OkHttp Dispatcher
    Process: took.out.the.package, PID: 10840
    java.util.ConcurrentModificationException
        at java.util.ArrayList.sort(ArrayList.java:1472)
        at java.util.Collections.sort(Collections.java:206)
        at took.out.the.package.imdb_activity.sortList(imdb_activity.java:257)

        at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:641)
        at java.lang.Thread.run(Thread.java:919)

它不会一直发生，我无法弄清楚为什么会发生。这是它调用的方法sortList：

public void sortList()
{
    Collections.sort(details, new Comparator<Movie>()
    {
        @Override
        public int compare(Movie left, Movie right)
        {
            Log.d("compare", "compare: left.getTitle().compareTo(right.getTitle()) = " + left.getTitle().compareTo(right.getTitle()));
            return left.getTitle().compareTo(right.getTitle());
        }
    });
    myAdapter.notifyDataSetChanged();
}

任何想法都很棒。我正在用Java执行此操作。
