java获取Android上列出的WIFI的Mac地址

Question

有没有办法获取wifi列表中每个wifi的mac地址

我目前的代码如下：

        wifiList = mainWifi.getScanResults();

        JSONArray requestData = new JSONArray();

        for (int i = 0; i < wifiList.size(); i++) {
            JSONObject wifiNetwork = new JSONObject();

            try {
                wifiNetwork.put("MSource", "WIFI");
                wifiNetwork.put("MName", (wifiList.get(i)).SSID);

                // this way I am getting mac address of current device.
                wifiNetwork.put("MAddress", mainWifi.getConnectionInfo().getMacAddress());

                wifiNetwork.put("MCreatedOn", "Some date time");
            } catch (JSONException e) {
                e.printStackTrace();
            }   
        }
