java.lang.IllegalStateException:适配器的内容已更改，但HederListView未收到通知

我正在我的项目中使用。它很好用。但在一个地方，当我尝试使用notifydatesetchanges时，它抛出了非法状态异常。只有当我尝试快速滚动列表视图时才会发生这种情况

这是堆栈跟踪

我尝试了许多解决方案，并通过大量搜索，但没有找到任何固溶体

这是我的密码

HeaderListView listView;
MyAdapter myAdapter;
ArrayList<String> eventList = new ArrayList<String>();

HeaderListView列表视图；
我的适配器我的适配器；
ArrayList eventList=新建ArrayList（）；

第一次获取列表的代码

private class GetList extends AsyncTask<String, Void, String> {

    ArrayList<String> loadMoreList;
    @Override
    public String doInBackground(String... params) {
        loadMoreList = WebFunctions.getEventList(params[0] ,params[1], params[2], params[3]);

        return null;
    }

    @Override
    public void onPreExecute() {

        }

    @Override
    public void onPostExecute(String string) {
        if(loadMoreList != null){
            if(loadMoreList.size() > 0){

                eventList.clear();
                eventList.addAll(loadMoreList);
                myAdapter = new MyAdapter(thisContext, eventList);
            } 
      }
}

private类GetList扩展了异步任务{
ArrayList loadMoreList；
@凌驾
公共字符串doInBackground（字符串…参数）{
loadMoreList=WebFunctions.getEventList（参数[0]，参数[1]，参数[2]，参数[3]）；
返回null；
}
@凌驾
公共无效onPreExecute（）{
}
@凌驾
public void onPostExecute（字符串）{
如果（loadMoreList！=null）{
如果（loadMoreList.size（）>0）{
eventList.clear（）；
addAll（loadMoreList）；
myAdapter=新的myAdapter（此上下文，事件列表）；
} 
}
}

代码以获取列表中的更多项

 private class LoadMoreList extends AsyncTask<String, Void, String> {

    ArrayList<String> loadMoreList;
    @Override
    public String doInBackground(String... params) {
        loadMoreList = WebFunctions.getEventList(params[0] ,params[1], params[2], params[3]);

        return null;
    }

    @Override
    public void onPreExecute() {

        }

    @Override
    public void onPostExecute(String string) {
        if(loadMoreList != null){
            if(loadMoreList.size() > 0){
                eventList.addAll(loadMoreList);
                myAdapter.notifyDataSetChanged();
        }
    }        
}

私有类LoadMoreList扩展了异步任务{
ArrayList loadMoreList；
@凌驾
公共字符串doInBackground（字符串…参数）{
loadMoreList=WebFunctions.getEventList（参数[0]，参数[1]，参数[2]，参数[3]）；
返回null；
}
@凌驾
公共无效onPreExecute（）{
}
@凌驾
public void onPostExecute（字符串）{
如果（loadMoreList！=null）{
如果（loadMoreList.size（）>0）{
addAll（loadMoreList）；
myAdapter.notifyDataSetChanged（）；
}
}        
}

实际上问题出在HeaderListView库中，但现在错误已被修复。

从中可以看出问题已经解决。

您必须从主UI线程调用

myAdapter.notifyDataSetChanged（）；

，onPostExecute被认为是UI线程。从这里调用LoadMoreList（）这个类日志cat文本而不是名为myAdapter.notifyDataSetChanged（）的图像，仍然会因相同的错误而崩溃。
