这里是填写可用 WiFi 连接列表的代码：

public class CustomListAdapter extends BaseAdapter {
    private final LayoutInflater inflater;

    public CustomListAdapter(Context context) {
        this.inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
        initListItems();
    }

    public void initListItems() {
        itemList = new ArrayList<>();
        List<ScanResult> scanResultsList = new ArrayList<>(); //wifiManager.getConfiguredNetworks();
        List<String> addedSSID = new ArrayList<>();

        for (ScanResult result : results) {
            if (!addedSSID.contains(result.SSID) && (result.SSID != null && !result.SSID.toLowerCase().contains("hh-"))) {
                scanResultsList.add(result);
                addedSSID.add(result.SSID);
            }
        }

        for (ScanResult scanResult : scanResultsList) {
            try {
                // exclude unnamed wifi
                if (scanResult.SSID == null || scanResult.SSID.length() == 0)
                    continue;

                HashMap<String, Object> map = new HashMap<String, Object>();
                map.put("SSID", scanResult.SSID.replace("\"", ""));
                map.put("BSSID", scanResult.BSSID);
                map.put("wifiConfiguration", scanResult);
                map.put("selected", false);
                itemList.add(map);
            } catch (Exception e) {
                e.printStackTrace();
            }
        }
    }

    @Override
    public int getCount() {
        return itemList.size();
    }

    @Override
    public Object getItem(int arg0) {
        return itemList.get(arg0);
    }

    @Override
    public long getItemId(int position) {
        return position;
    }

    @Override
    public View getView(int position, View convertView, ViewGroup parent) {
        MainListHolder mHolder;

        View v = convertView;
        if (convertView == null) {
            mHolder = new MainListHolder();
            v = inflater.inflate(R.layout.wifi_entry_item, null);
            mHolder.tvNetworkName = v.findViewById(R.id.networkName);
            v.setTag(mHolder);
        } else {
            mHolder = (MainListHolder) v.getTag();
        }

        HashMap<String, Object> item = itemList.get(position);
        mHolder.tvNetworkName.setText((String) item.get("SSID"));
        return v;
    }

    class MainListHolder {
        private TextView tvNetworkName;
    }
}

当我在某些情况下按下按钮并且仅针对少数 Android 手机时，我得到了这个神秘的错误：

真的，我无法理解这个堆栈跟踪，有什么帮助吗？

更新

这段代码正在打开一个对话框，用于选择 WiFi 连接。

此错误仅发生在特定手机（目前）华为。
