Question

想对此代码发表您的意见。

private String getIpAddress(){
  String ip = "";
  try {
  Enumeration<NetworkInterface> enumNetworkInterfaces = NetworkInterface.getNetworkInterfaces();
   while(enumNetworkInterfaces.hasMoreElements()){
    NetworkInterface networkInterface = enumNetworkInterfaces.nextElement();
    Enumeration<InetAddress> enumInetAddress = networkInterface.getInetAddresses();
      while(enumInetAddress.hasMoreElements()){
        InetAddress inetAddress = enumInetAddress.nextElement();

        String ipAddress = "";
        if(inetAddress.isSiteLocalAddress()){
           ipAddress = "SiteLocalAddress: ";

           ip += inetAddress.getHostAddress() + "\n"; 
        }
       }

   } catch (SocketException e) {
       // TODO Auto-generated catch block
       e.printStackTrace();
       ip += "Something Wrong! " + e.toString() + "\n";
   }

 return ip;
 }

private void MDConnector() {
  setMobileDataEnabled (MainActivity.this,true);
  String ip = getIpAddress();
    do {
         addMessage("..")
         try{
            Thread.sleep(1000L);
         }catch (InterruptedException localInterruptedException){
         }
      }while (ip.length() <= 0);
     MDConnect();
 }

它没有用。我的目标是：connect-＆gt; getIPAddress-＆gt;如果没有，请等到我得到一个＆gt;然后转到另一个方法。我的代码有什么问题？谁能帮我？提前谢谢。

编辑：添加了getIpAddress代码。积分到http://android-er.blogspot.jp/2014/02/get-my-ip-address.html

在do-while循环中，ip-String不会被更改。尝试将获取ip-String IP的部分移动到try-block中。

使用do-while语句等待连接 - java android
