1. 獲取手機IP地址

第一步：新增許可權

<uses-permission android:name="android.permission.INTERNET"/>

第二步：上程式碼
2333

 private String getIP() {
        String IP = "";
        StringBuilder IPStringBuilder = new StringBuilder();
        try {
            Enumeration<NetworkInterface> networkInterfaceEnumeration = NetworkInterface.getNetworkInterfaces
 
();
            while (networkInterfaceEnumeration.hasMoreElements()) {
                NetworkInterface networkInterface = networkInterfaceEnumeration.nextElement();
                Enumeration<InetAddress> inetAddressEnumeration = networkInterface.getInetAddresses();
                while (inetAddressEnumeration.hasMoreElements
 
()) {
                    InetAddress inetAddress = inetAddressEnumeration.nextElement();
                    if (!inetAddress.isLoopbackAddress()
                            && !inetAddress.isLinkLocalAddress()
                            && inetAddress.isSiteLocalAddress()) {
                        IPStringBuilder.append
 
(inetAddress.getHostAddress().toString() + "\n");
                    }
                }
            }
        } catch (SocketException ex) {
        }
        IP = IPStringBuilder.toString();
        if (IP.indexOf("\n1") > 0) {
            IP = IP.substring(0, IP.indexOf("\n1"));
        }
            //返回一個XXX.XXX.xxx.xxx格式的IP地址
        return IP;
    }

1. 獲取MAC地址

獲取MAC地址。是通過WIFIManager獲取的。

WifiManager WiFi = (WifiManager)getSystemService(Context.WIFI_SERVICE);
WifiInfo info = WiFi.getConnectionInfo();
//通過wifiinfo獲取獲取到MAC地址了
 String ssid = (info .getSSID() == "<unknown ssid>" ? "無連線WIFI" : info .getSSID());
                if (!CommonUtils.isEmpty(ssid)) {
                    ToastShow.showToast("正在連線：" + ssid);
                    String data=
                                     "MAC地址 = "+info .getMacAddress()+"\n"
                                    +"訊號強度 = "+info .getRssi()+"\n"
                                    +"正在連線 = "+ ssid +"\n"
                                    +"getBSSID = "+info .getBSSID()+"\n";

其中getSSID得到的是連線到WIFI的名字。getBSSID得到的是十六進位制字串？有知道的同志留言評論的告訴我一下唄。
