Autocompletetextview:java.lang.IllegalStateException：adapter的内容已经改变但是ListView没有收到通知

Question

当我点击 autocompletetextview.I 中的某个项目时，我有时会遇到异常，这不是运行这在后台线程中，我正在使用 notifyDataSetChanged() also.I 无法理解在哪里我错了吗

java.lang.IllegalStateException: 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.

代码

 searchautocomplete.setAdapter(searchAutoCompleteAdapter= new SearchAutoCompleteAdapter(getApplicationContext(),searchautocomplete.getText().toString(),this)); // 'this' is Activity instance
      searchautocomplete.setLoadingIndicator(
               (android.widget.ProgressBar) findViewById(R.id.pb_loading_indicator));
 searchautocomplete.setOnItemClickListener(new AdapterView.OnItemClickListener()
        {
            @Override
            public void onItemClick(AdapterView<?> parent, View view, int position, long id)
            {
                UserVideo data=(UserVideo)parent.getItemAtPosition(position);
                searchautocomplete.setText("");
                if ((data.getIsVideo()))
                {

                    searchAutoCompleteAdapter.notifyDataSetChanged();
                    setSearchVideoToShow(data);
                    mSearchLayout.setVisibility(View.GONE);
                    switchFragment(HomeActivity.FRAGMENT_VIDEO_SEARCH, false, "Video Details");
                }
                else if ((!data.getIsVideo()))
                {
                    searchAutoCompleteAdapter.notifyDataSetChanged();
                    //mSingleClickHandle.put(ENABLE_FRAGMENT_SEARCH_VIEW, false);
                    setUserIdToShow(data.getUserId2());
                    closeDrawer();
                    mSearchLayout.setVisibility(View.GONE);
                    switchFragment(HomeActivity.FRAGMENT_PROFILE_VIEW, false, "video");
                }
            }
        });

添加notifyDataSetChanged()；在我内部 API 调用的 onResponse() 内部解决了我的问题..
