Question

我有问题。抱歉英文不好。

我的Android应用程序在滚动列表并按下任何按钮后崩溃了。在堆栈跟踪中：

   The content of the adapter has changed but ListView did not receive a notification.
   Make sure the content of your adapter is not modified from a background thread, but only from the UI thread. 
   Make sure your adapter calls notifyDataSetChanged() when its content changes.

适配器的内容未发生变化。滚动并单击其中的另一个按钮时会发生错误。单击按钮后使用相同的listView，但内容不同。

这是我的代码： CustomAdapter.getView

private ArrayList<ListData> eventsRecommended;
private ArrayList<ListData> eventsAll;

@Override
public View getView(final int position, View convertView, ViewGroup parent) {

    ViewHolder holder;
    View rowView = convertView;
    if ( rowView == null )
    {
        LayoutInflater inflater = (LayoutInflater) context.getSystemService( Context.LAYOUT_INFLATER_SERVICE );
        rowView = inflater.inflate(R.layout.inetlist, null, true);
        holder = new ViewHolder();
        holder.eventTitle = (TextView) rowView.findViewById(R.id.title);
        holder.eventDescription = (TextView) rowView.findViewById(R.id.description);
        holder.eventImage = (ImageView) rowView.findViewById(R.id.imageView1);
        holder.eventTickets = (Button) rowView.findViewById(R.id.buyTicketButton);
        rowView.setTag(holder);
    }
    else
    {
        holder = (ViewHolder) rowView.getTag();
    }

    ListData p = getItem(position);
    holder.eventTitle.setText(p.title);
    holder.eventDescription.setText(p.description);
    if ( p.ticketLink == null || p.ticketLink.length() < 1 )
        holder.eventTickets.setVisibility(View.INVISIBLE);
    else
        holder.eventTickets.setVisibility(View.VISIBLE);
    holder.eventTickets.setOnClickListener(onClickListener);
    holder.eventImage.setImageDrawable(getDrawable(p.pic));

    return rowView;
}

按钮点击更改标志的布尔值

public ListData getItem(int position)
{
    try
    {
        if (flag == Boolean.FALSE)
            return eventsRecommended.get(position);
        else
            return eventsAll.get(position);
    }
    catch (Exception e) {}
    return null;
}

单击按钮后尝试使用其他自定义列表视图适配器。它会崩溃吗？可能有问题吗？
