I found the code for obtaining the ip address of phone owns wifi router
我找到了获取手机拥有wifi路由器的ip地址的代码
WifiManager myWifiManager = (WifiManager) getSystemService(WIFI_SERVICE);
WifiInfo myWifiInfo = myWifiManager.getConnectionInfo();
int ipAddress = myWifiInfo.getIpAddress();
System.out.println("WiFi address is " + android.text.format.Formatter.formatIpAddress(ipAddress))

What you want is DhcpInfo....
你要的是DhcpInfo……
final WifiManager manager = (WifiManager) super.getSystemService(WIFI_SERVICE);
final DhcpInfo dhcp = manager.getDhcpInfo();
final String address = Formatter.formatIpAddress(dhcp.gateway);
This will determine the formatted gateway IP address, which should be what you're looking for.
这将确定格式化的网关 IP 地址，这应该是您要查找的。

Since formatIpAddress is Deprecatted, here is the alternative :
由于 formatIpAddress 已弃用，这里是替代方案：
public String getHotspotAdress(){
final WifiManager manager = (WifiManager)super.getSystemService(WIFI_SERVICE);
final DhcpInfo dhcp = manager.getDhcpInfo();
int ipAddress = dhcp.gateway;
ipAddress = (ByteOrder.nativeOrder().equals(ByteOrder.LITTLE_ENDIAN)) ?
Integer.reverseBytes(ipAddress) : ipAddress;
byte[] ipAddressByte = BigInteger.valueOf(ipAddress).toByteArray();
try {
InetAddress myAddr = InetAddress.getByAddress(ipAddressByte);
return myAddr.getHostAddress();
} catch (UnknownHostException e) {
// TODO Auto-generated catch block
Log.e("Wifi Class", "Error getting Hotspot IP address ", e);
}
return "null"
}
