            new PublicIPAddress().execute();

        protected void onPostExecute(String string) {
            Lg.d("deviceIpAddress", string);

下面的代码可能会帮助你..不要忘记添加权限..

public String getLocalIpAddress(){
   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();
                }
           }
       }
       } catch (Exception ex) {
          Log.e("IP Address", ex.toString());
      }
      return null;
}

在清单文件中添加以下权限。

 <uses-permission android:name="android.permission.INTERNET" />
 <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />

编码快乐! !

引用 // get设备Ip地址

open fun getLocalIpAddress(): String? {
    try {
        val en: Enumeration<NetworkInterface> = NetworkInterface.getNetworkInterfaces()
        while (en.hasMoreElements()) {
            val networkInterface: NetworkInterface = en.nextElement()
            val enumerationIpAddress: Enumeration<InetAddress> = networkInterface.inetAddresses
            while (enumerationIpAddress.hasMoreElements()) {
                val inetAddress: InetAddress = enumerationIpAddress.nextElement()
                if (!inetAddress.isLoopbackAddress && inetAddress is Inet4Address) {
                    return inetAddress.getHostAddress()
                }
            }
        }
    } catch (ex: SocketException) {
        ex.printStackTrace()
    }
    return null
}

简单地使用凌空从这个网站获得ip

RequestQueue queue = Volley.newRequestQueue(this);    
String urlip = "http://checkip.amazonaws.com/";

    StringRequest stringRequest = new StringRequest(Request.Method.GET, urlip, new Response.Listener<String>() {
        @Override
        public void onResponse(String response) {
            txtIP.setText(response);

        }
    }, new Response.ErrorListener() {
        @Override
        public void onErrorResponse(VolleyError error) {
            txtIP.setText("didnt work");
        }
    });

    queue.add(stringRequest);

请检查这个代码…使用此代码。我们将从移动互联网获得IP…

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();
                    }
                }
            }

老实说，我对代码安全只是有点熟悉，所以这可能有点像黑客。但对我来说，这是最通用的方法:

package com.my_objects.ip;

import java.net.InetAddress;
import java.net.UnknownHostException;

public class MyIpByHost 
{
  public static void main(String a[])
  {
   try 
    {
      InetAddress host = InetAddress.getByName("nameOfDevice or webAddress");
      System.out.println(host.getHostAddress());
    } 
   catch (UnknownHostException e) 
    {
      e.printStackTrace();
    }
} }
