IllegalStateException：适配器的内容发生了变化但ListView没有收到通知？

Question

我正在工作的应用程序中，我必须显示可用 wifi 的自定义列表。为此，我在重写方法中获取列表：

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

从这里，我调用 setAdapter。一旦列表显示它滚动正常而没有任何崩溃但是当我单击任何列表项以连接该wifi时提供密码 返回列表调用以下方法：-

 private int counter;
@Override
public void onConnectivityChange(final NetworkInfo info) {
         int len = mItems.size();

        for (int index = 0; index < len; index++) {
            WifiListData item = mItems.get(index);
            item.setIsConnected(false); // setting each to not connected
            item.setState(null);
            if (item.getSSID()!=null&&item.getSSID().equals(info.getExtraInfo().replace("\"", ""))) {
                item.setIsConnected(info.isConnected());
                item.setState(getStatusInSimpleEnglish(info.getDetailedState()));
            }
        }
        if (info.isConnected()) {
            mTimerHandler.removeCallbacks(mTimerRunnable);
        }
        if (info.isConnected() && info.getExtraInfo().equals(String.format("\"%s\"", mSelectedSSID))) {
            DebugLogger.d(TAG, "Connected to " + info.getExtraInfo());
            dismissProgressDialog();
            mSelectedSSID = "";
        }

        if (info.getState() == NetworkInfo.State.CONNECTED) {
            Collections.sort(mItems, new RssiComparator());
            putConnectedOnTop();
            Handler handler = new Handler();
            handler.postDelayed(new Runnable() {
                @Override
                public void run() {
                  connectTOSignIn();
                }
            },1000);
        }
        if (info.getState() == NetworkInfo.State.CONNECTING) {
            Collections.sort(mItems, new RssiComparator());
            putConnectedOnTop();
        }
        notifyAdapter();
}

当我开始滚动应用程序时，堆栈跟踪会崩溃：-

[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.

我在 UI 线程中发出通知：-

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

非常感谢任何建议，谢谢。

要仅更新列表视图中的一行，您可以尝试一下 -> answer
