写一个工具类
public class Tools {
public static 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().toString();
}
}
}
} catch (SocketException ex) {
Log.e("出错啦", ex.toString());
}
return null;
}
}
然后
WifiManager wm = (WifiManager)getSystemService(WIFI_SERVICE);
WifiInfo wi = wm.getConnectionInfo();
System.out.println("IP地址是："+Tools.getLocalIpAddress());
System.out.println("SSID："+wi.getSSID());
最后记得加两个权限
<uses-permission android:name="android.permission.INTERNET"/>
<uses-permission android:name="android.permission.ACCESS_WIFI_STATE"/>
