我总是得到最后一个wifiInfo。我怎样才能获得当前的wifiInfo

Question

连接到wifi时，我总是得到最后一个wifiInfo。例如，手机现在连接到wifi-a，然后我启动程序，手机连接到wifi-b，但我得到的是wifi-a wifiInfo。我该如何解决？ 谢谢

@Override
public void run() {
    if (wifiConnectFlag == 0) {
        Log.e(TAG, "connect wifi start...");
        wifiAdmin = new WifiAdmin(getApplicationContext());
        wifiAdmin.openWifi();
        boolean b = wifiAdmin.disconnectWifi();
        Log.d(TAG, "run: "+b);
        WifiConfiguration wificon = wifiAdmin.CreateWifiInfo("MERCURY_954F4C", "", 1);
        wifiAdmin.addNetwork(wificon);
        wifiConnectFlag = 1;
        Log.e(TAG, "connect successed");
        String ssid = wifiAdmin.getSSID();
        String bssid = wifiAdmin.getBSSID();
        int id = wifiAdmin.getNetworkId();
        String ipString = wifiAdmin.intToIp(wifiAdmin.getIPAddress());
        Log.e("IP", "ip: "+ipString+" id: "+id+" ssid: "+ssid+" bssid: "+bssid);
        //Log.e(TAG, String.valueOf(wifiAdmin.getIPAddress()));            
    }
}
