Android IllegalStateException:适配器的内容已更改，但ListView未收到通知？

我正在使用的应用程序中，我必须显示可用wifi的自定义列表。为此，我在重写的方法中获取列表：

public void onScanComplete(List<ScanResult> results) {}

我在UI线程内发出通知，如下所示：-

private  void notifyAdapter()  {
   mActivity.runOnUiThread(new Runnable() {
        @Override
        public void run() {
            homeWifiListAdapter.notifyDataSetChanged();
            }
    });
}

非常感谢您的任何建议。

要更新listview中的一行，您可以尝试一下->

这个技巧是Roman Guy发明的

也许它缺少了将新数据传递给listview的部分？@Simone Leoni感谢您的回复，实际上列表是全局列表，没有更改创建的列表。connectTOSignIn方法会改变您的mItems吗？但是我认为您不能这样做，您正在修改listview中存储和使用的内容。将新数据传递到适配器应该可以解决此问题！然后打电话给著名的notifyDataSetChanged@SimoneLeoni不，我没有在connectTOSignIn方法中执行任何与列表相关的操作。-重复我自己：-我认为您不能这样做，您正在修改listview中存储和使用的内容。将新数据传递到适配器应该可以解决此问题！然后打电话给著名的“改变”

[null]=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.
