在你的AndroidManifest.xml 文件

您的代码：

ConnectivityManager connectivityManager = (ConnectivityManager) getApplicationContext().getSystemService(Service.CONNECTIVITY\_SERVICE);

/\* you can print your active network via using below \*/

Log.i("myNetworkType: ", connectivityManager.getActiveNetworkInfo().getTypeName());

WifiManager wifiManager= (WifiManager) getApplicationContext().getSystemService(getApplicationContext().WIFI\_SERVICE);

Log.i("routes ", connectivityManager.getLinkProperties(connectivityManager.getActiveNetwork()).getRoutes().toString());

Log.i("domains ", connectivityManager.getLinkProperties(connectivityManager.getActiveNetwork()).getDomains().toString());

Log.i("ip address ", connectivityManager.getLinkProperties(connectivityManager.getActiveNetwork()).getLinkAddresses().toString());

Log.i("dns address ", connectivityManager.getLinkProperties(connectivityManager.getActiveNetwork()).getDnsServers().toString());

if(connectivityManager.getActiveNetworkInfo().getType() == ConnectivityManager.TYPE\_WIFI) \{

Log.i("myType ", "wifi");

DhcpInfo d =wifiManager.getDhcpInfo();

Log.i("info", d.toString()+"");

else if(connectivityManager.getActiveNetworkInfo().getType() == ConnectivityManager.TYPE\_ETHERNET) \{

/\* there is no EthernetManager class, there is only WifiManager. so, I used this below trick to get my IP range, dns, gateway address etc \*/

Log.i("myType ", "Ethernet");

Log.i("routes ", connectivityManager.getLinkProperties(connectivityManager.getActiveNetwork()).getRoutes().toString());

Log.i("domains ", connectivityManager.getLinkProperties(connectivityManager.getActiveNetwork()).getDomains().toString());

Log.i("ip address ", connectivityManager.getLinkProperties(connectivityManager.getActiveNetwork()).getLinkAddresses().toString());

Log.i("dns address ", connectivityManager.getLinkProperties(connectivityManager.getActiveNetwork()).getDnsServers().toString());

else \{

不能达到知道你是否是通过WiFi或网络使用WifiManager为WifiManager只带wifi连接交易。您必须使用ConnectivityManager。我再次更新了代码WifiManager和ConnectivityManager以生成您想要的结果。
