如何以编程方式获取android中连接的wifi路由器的IP地址？

Question

我想获取我的Android手机所连接的wifi路由器的IP地址？我知道我们可以通过使用android APIS获取mac / BSSId和SSID，但我找不到找到找到它的IP地址的方法吗？

我发现获取手机IP地址的代码拥有wifi路由器

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))

但未能得到我想要的东西

Answer 1

你想要的是DhcpInfo ....

final WifiManager manager = (WifiManager) super.getSystemService(WIFI_SERVICE);
final DhcpInfo dhcp = manager.getDhcpInfo();
final String address = Formatter.formatIpAddress(dhcp.gateway);

这将确定格式化的网关IP地址，这应该是您正在寻找的。

由于formatIpAddress是Deprecatted，以下是替代方法：

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"
}
