是否可以使用一些代码获得设备的IP地址?
当前回答
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();
}
}
}

kotlin语言。
fun contextIP(context: Context): String {
val wm: WifiManager = context.getSystemService(Context.WIFI_SERVICE) as WifiManager
return Formatter.formatIpAddress(wm.connectionInfo.ipAddress)
}
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() && inetAddress instanceof Inet4Address) {
return inetAddress.getHostAddress();
}
}
}
} catch (SocketException ex) {
ex.printStackTrace();
}
return null;
}
我已经添加了inetAddress instanceof Inet4Address来检查它是否是ipv4地址。
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
}
在AndroidManifest.xml中声明ACCESS_WIFI_STATE权限:
<uses-permission
android:name="android.permission.ACCESS_WIFI_STATE"/>
可以通过WifiManager获取IP地址:
Context context = requireContext().getApplicationContext();
WifiManager wm = (WifiManager) context.getSystemService(Context.WIFI_SERVICE);
String ip = Formatter.formatIpAddress(wm.getConnectionInfo().getIpAddress());
WifiManager wm = (WifiManager) getSystemService(WIFI_SERVICE);
String ipAddress = BigInteger.valueOf(wm.getDhcpInfo().netmask).toString();
