安卓使用WifiManager方法连接wifi后以前记住密码的wifi显示已停用

Question

  public WifiConfiguration CreateWifiInfo(String SSID, String Password, int Type) 
    { 
          WifiConfiguration config = new WifiConfiguration();   
           config.allowedAuthAlgorithms.clear();

          WifiConfiguration tempConfig = this.IsExsits(SSID);           
          if(tempConfig != null) {  
              mWifiManager.removeNetwork(tempConfig.networkId);  
          }

          if(Type == 1) //WIFICIPHER_NOPASS
          { 
               config.wepKeys[0] = "\"\""; 
               config.allowedKeyManagement.set(WifiConfiguration.KeyMgmt.NONE); 
               config.wepTxKeyIndex = 0; 
          } 
          if(Type == 2) //WIFICIPHER_WEP
          { 
              config.hiddenSSID = true;

          { 
          config.preSharedKey = "\""+Password+"\""; 
          config.hiddenSSID = true;   
          config.allowedAuthAlgorithms.set(WifiConfiguration.AuthAlgorithm.OPEN);   
          config.allowedGroupCiphers.set(WifiConfiguration.GroupCipher.TKIP);                         
          config.allowedKeyManagement.set(WifiConfiguration.KeyMgmt.WPA_PSK);                         
          config.allowedPairwiseCiphers.set(WifiConfiguration.PairwiseCipher.TKIP);

          config.allowedPairwiseCiphers.set(WifiConfiguration.PairwiseCipher.CCMP);
          config.status = WifiConfiguration.Status.ENABLED;   
          }
           return config; 
    } 

  // 添加一个网络并连接  
    public void addNetwork(WifiConfiguration wcg) { 
     int wcgID = mWifiManager.addNetwork(wcg); 
     boolean b =  mWifiManager.enableNetwork(wcgID, true); 
     System.out.println("a--" + wcgID);
     System.out.println("b--" + b);
    }

这个问题是不是连接wifi的时候要先断开自己的连接？
