Java Android-使用wifi、热点、usb或蓝牙共享时获取本地IP地址

当热点打开或连接到wifi网络或通过蓝牙时，我需要Android手机的本地IP地址

我已经使用了这两个代码

第一个代码在所有情况下都给出“10.0.2.5”，第二个代码在连接到wifi网络时给出正确的IP地址。但当热点出现时，给出“0.0.0.0”

第一个代码段

public static String getIpAddress() {
    try {
        for (Enumeration en = NetworkInterface.getNetworkInterfaces(); en.hasMoreElements();) {
            NetworkInterface intf = (NetworkInterface) en.nextElement();
            for (Enumeration enumIpAddr = intf.getInetAddresses(); enumIpAddr.hasMoreElements();) {
                InetAddress inetAddress = (InetAddress) enumIpAddr.nextElement();

                if (!inetAddress.isLoopbackAddress() && inetAddress instanceof Inet4Address) {
                    String ipAddress = inetAddress.getHostAddress().toString();
                    Log.e("IP address", "" + ipAddress);
                    return ipAddress;
                }
            }
        }
    } catch (SocketException ex) {
        Log.e("MASOOM", ex.toString());
    }
    return null;
}

public String getIpAddress(){
    WifiManager wifiManager = (WifiManager) this.getSystemService(WIFI_SERVICE);
    int ipAddress = wifiManager.getConnectionInfo().getIpAddress();
    return String.format("%d.%d.%d.%d", (ipAddress & 0xff), (ipAddress >> 8 & 0xff),(ipAddress >> 16 & 0xff), (ipAddress >> 24 & 0xff));
}

第二个代码段

public static String getIpAddress() {
    try {
        for (Enumeration en = NetworkInterface.getNetworkInterfaces(); en.hasMoreElements();) {
            NetworkInterface intf = (NetworkInterface) en.nextElement();
            for (Enumeration enumIpAddr = intf.getInetAddresses(); enumIpAddr.hasMoreElements();) {
                InetAddress inetAddress = (InetAddress) enumIpAddr.nextElement();

                if (!inetAddress.isLoopbackAddress() && inetAddress instanceof Inet4Address) {
                    String ipAddress = inetAddress.getHostAddress().toString();
                    Log.e("IP address", "" + ipAddress);
                    return ipAddress;
                }
            }
        }
    } catch (SocketException ex) {
        Log.e("MASOOM", ex.toString());
    }
    return null;
}

public String getIpAddress(){
    WifiManager wifiManager = (WifiManager) this.getSystemService(WIFI_SERVICE);
    int ipAddress = wifiManager.getConnectionInfo().getIpAddress();
    return String.format("%d.%d.%d.%d", (ipAddress & 0xff), (ipAddress >> 8 & 0xff),(ipAddress >> 16 & 0xff), (ipAddress >> 24 & 0xff));
}

请提供正确的代码

字符串ip=“”；
String ip = "";
        try {
            Enumeration<NetworkInterface> enumNetworkInterfaces = NetworkInterface.getNetworkInterfaces();
            while (enumNetworkInterfaces.hasMoreElements()) {
                NetworkInterface networkInterface = enumNetworkInterfaces.nextElement();
                Enumeration<InetAddress> enumInetAddress = networkInterface.getInetAddresses();
                while (enumInetAddress.hasMoreElements()) {
                    InetAddress inetAddress = enumInetAddress.nextElement();
                    if (inetAddress.isSiteLocalAddress()) {
                        ip += inetAddress.getHostAddress() + " | ";
                    }
                }
            }
        } catch (SocketException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
        return ip;

试一试{
枚举枚举enumNetworkInterfaces=NetworkInterface.getNetworkInterfaces（）；
while（enumNetworkInterfaces.hasMoreElements（））{
NetworkInterface NetworkInterface=enumNetworkInterfaces.nextElement（）；
枚举Enumeration enumInetAddress=networkInterface.getInetAddresses（）；
while（enumInetAddress.hasMoreElements（））{
InetAddress InetAddress=enumInetAddress.nextElement（）；
if（inetAddress.isSiteLocalAddress（））{
ip+=inetAddress.getHostAddress（）+“|”；
}
}
}
}捕获（SocketException e）{
//TODO自动生成的捕捉块
e、 printStackTrace（）；
}
返回ip；
