你可以使用LinkProperties。建议用于新的Android版本。

此功能检索WiFi和移动数据的本地IP地址。它需要Manifest.permission。ACCESS_NETWORK_STATE许可。

@Nullable
public static String getDeviceIpAddress(@NonNull ConnectivityManager connectivityManager) {
    LinkProperties linkProperties = connectivityManager.getLinkProperties(connectivityManager.getActiveNetwork());
    InetAddress inetAddress;
    for(LinkAddress linkAddress : linkProperties.getLinkAddresses()) {
        inetAddress = linkAddress.getAddress();
        if (inetAddress instanceof Inet4Address
                && !inetAddress.isLoopbackAddress()
                && inetAddress.isSiteLocalAddress()) {
            return inetAddress.getHostAddress();
        }
    }
    return null;
}

如果你有一个壳;Ifconfig eth0也适用于x86设备

private InetAddress getLocalAddress()throws IOException {

            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();
                            return inetAddress;
                        }
                    }
                }
            } catch (SocketException ex) {
                Log.e("SALMAN", ex.toString());
            }
            return null;
        }

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
}

我使用以下代码: 我使用hashCode的原因是因为当我使用getHostAddress时，我得到了一些垃圾值附加到ip地址。但是hashCode对我来说工作得很好，这样我就可以使用Formatter来获得具有正确格式的ip地址。

下面是示例输出:

1.使用 getHostAddress ： ***** IP=fe80：：65ca：a13d：ea5a：233d%rmnet_sdio0

2.使用hashCode和Formatter: ***** IP=238.194.77.212

如你所见，第二种方法正好满足了我的需求。

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()) {
                    String ip = Formatter.formatIpAddress(inetAddress.hashCode());
                    Log.i(TAG, "***** IP="+ ip);
                    return ip;
                }
            }
        }
    } catch (SocketException ex) {
        Log.e(TAG, ex.toString());
    }
    return null;
}

 //    @NonNull
    public static String getIPAddress() {
        if (TextUtils.isEmpty(deviceIpAddress))
            new PublicIPAddress().execute();
        return deviceIpAddress;
    }

    public static String deviceIpAddress = "";

    public static class PublicIPAddress extends AsyncTask<String, Void, String> {
        InetAddress localhost = null;

        protected String doInBackground(String... urls) {
            try {
                localhost = InetAddress.getLocalHost();
                URL url_name = new URL("http://bot.whatismyipaddress.com");
                BufferedReader sc = new BufferedReader(new InputStreamReader(url_name.openStream()));
                deviceIpAddress = sc.readLine().trim();
            } catch (Exception e) {
                deviceIpAddress = "";
            }
            return deviceIpAddress;
        }

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