我用了这个，它奏效了！
WifiManager wm = (WifiManager) getSystemService(WIFI_SERVICE);
String ip = Formatter.formatIpAddress(wm.getConnectionInfo().getIpAddress());
Below permissions in the manifest file.
下面是清单文件中的权限。
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<uses-permission android:name="android.permission.ACCESS_WIFI_STATE"/>

You can use this method to get IP address of the device pass true for IPv4 and false for IPv6
您可以使用此方法获取设备的 IP 地址，IPv4 为 true，IPv6 为 false
public static String getIPAddress(boolean useIPv4) {
try {
List<NetworkInterface> interfaces = Collections.list(NetworkInterface.getNetworkInterfaces());
for (NetworkInterface intf : interfaces) {
List<InetAddress> addrs = Collections.list(intf.getInetAddresses());
for (InetAddress addr : addrs) {
if (!addr.isLoopbackAddress()) {
String sAddr = addr.getHostAddress();
//boolean isIPv4 = InetAddressUtils.isIPv4Address(sAddr);
boolean isIPv4 = sAddr.indexOf(':')<0;
if (useIPv4) {
if (isIPv4)
return sAddr;
} else {
if (!isIPv4) {
int delim = sAddr.indexOf('%'); // drop ip6 zone suffix
return delim<0 ? sAddr.toUpperCase() : sAddr.substring(0, delim).toUpperCase();
}
}
}
}
}
} catch (Exception ex) { } // for now eat exceptions
return "";
}
