使用wifi ip的位置

Question

我试图找到我的网络ip，并使用该ip获取位置。但是，当连接到2G网络时，我的代码会返回正确的IP（223.187.19.157）。但是，当我连接到我的无线网络，它会返回像这样的IP fe80 :: 7ad6：f0ff：fe2b：dca6％wlan0。任何人都可以请帮我找到我的无线上网ip格式正确。代码如下

public String getIpAddress() { 
     try { 
      for (Enumeration<NetworkInterface> en = NetworkInterface.getNetworkInterfaces(); en.hasMoreElements();) { 
       NetworkInterface intf = en.nextElement(); 
       for (Enumeration<InetAddress> enumIpAddr = intf.getInetAddresses(); enumIpAddr.hasMoreElements();) { 
        InetAddress inetAddress = enumIpAddr.nextElement(); 
        if (!inetAddress.isLoopbackAddress()) { 
         return inetAddress.getHostAddress().toString(); 
        } 
       } 
      } 
     } catch (SocketException ex) { 
      ex.printStackTrace(); 
     } 
     return null; 
    }
