设置阵列适配器列表视图

Question

此代码可在BlueStacks中工作，但当智能手机运行时在日志中显示以下错误。

错误:

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. [in ListView(2131296334, class
android.widget.ListView) with Adapter(class android.widget.HeaderViewListAdapter)]

代码:

private void displayResultList() {
        try {
        array.clear();
        array=baseHelper.results;
        tView.setText("Size : " +array.size()+" "+ baseHelper.countmcur );
            try {
                if(arrayAdapter!=null)
                    arrayAdapter.notifyDataSetChanged();
                 arrayAdapter=new display();
                listV.setAdapter(arrayAdapter);
                arrayAdapter.notifyDataSetChanged();
            } catch (Exception e) {
             message.messages(contex, e.getMessage());
            }
            listV.setTextFilterEnabled(true);
        } catch (Exception e) {
             message.messages(contex, e.getMessage());
        }

        }

在您从适配器更改数据后，您应该调用notifydatachchange。接下来，调试代码以找出哪一列出现错误。除此之外，如果有出现错误
