安卓 获取手机IP地址的实现代码
1.获取手机IP地址的代码:
public static String getLocalIpAddress(){ try{ for (Enumeration<NetworkInterface> en = NetworkInterface.getNetworkInterfaces(); en.hasMoreElements();) { NetworkInterface intf = en.nextElement(); for (Enumeration<InetAddress> enumIpAddr = intf .getInetAddresses(); enumIpAddr.hasMoreElements();) { InetAddress inetAddress = enumIpAddr.nextElement(); if (!inetAddress.isLoopbackAddress()) { return inetAddress.getHostAddress().toString(); } } } }catch (SocketException e) { // TODO: handle exception Utils.log("WifiPreference IpAddress---error-" + e.toString()); } return null; }
但是在4.0 下 会出现类似fe80::b607:f9ff:fee5:487e的IP地址, 这个是IPV6的地址,我们需要获得是的IPV4的地址,所以要在上诉代码中加一个判断
InetAddressUtils.isIPv4Address(inetAddress.getHostAddress());
2.完整代码如下:
public static String getLocalIpAddress(){ try{ for (Enumeration<NetworkInterface> en = NetworkInterface.getNetworkInterfaces(); en.hasMoreElements();) { NetworkInterface intf = en.nextElement(); for (Enumeration<InetAddress> enumIpAddr = intf .getInetAddresses(); enumIpAddr.hasMoreElements();) { InetAddress inetAddress = enumIpAddr.nextElement(); if (!inetAddress.isLoopbackAddress() && InetAddressUtils.isIPv4Address(inetAddress.getHostAddress())) { return inetAddress.getHostAddress().toString(); } } } }catch (SocketException e) { // TODO: handle exception Utils.log("WifiPreference IpAddress---error-" + e.toString()); } return null; }
获取android手机当前ip地址
public class NetWorkUtils { /** * 检查网络是否可用 * * @param paramContext * @return */ public static boolean checkEnable(Context paramContext) { boolean i = false; NetworkInfo localNetworkInfo = ((ConnectivityManager) paramContext .getSystemService("connectivity")).getActiveNetworkInfo(); if ((localNetworkInfo != null) && (localNetworkInfo.isAvailable())) return true; return false; } /** * 将ip的整数形式转换成ip形式 * * @param ipInt * @return */ public static String int2ip(int ipInt) { StringBuilder sb = new StringBuilder(); sb.append(ipInt & 0xFF).append("."); sb.append((ipInt >> 8) & 0xFF).append("."); sb.append((ipInt >> 16) & 0xFF).append("."); sb.append((ipInt >> 24) & 0xFF); return sb.toString(); } /** * 获取当前ip地址 * * @param context * @return */ public static String getLocalIpAddress(Context context) { try { // for (Enumeration<NetworkInterface> en = NetworkInterface // .getNetworkInterfaces(); en.hasMoreElements();) { // NetworkInterface intf = en.nextElement(); // for (Enumeration<InetAddress> enumIpAddr = intf // .getInetAddresses(); enumIpAddr.hasMoreElements();) { // InetAddress inetAddress = enumIpAddr.nextElement(); // if (!inetAddress.isLoopbackAddress()) { // return inetAddress.getHostAddress().toString(); // } // } // } WifiManager wifiManager = (WifiManager) context .getSystemService(Context.WIFI_SERVICE); WifiInfo wifiInfo = wifiManager.getConnectionInfo(); int i = wifiInfo.getIpAddress(); return int2ip(i); } catch (Exception ex) { return " 获取IP出错鸟!!!!请保证是WIFI,或者请重新打开网络!\n" + ex.getMessage(); } // return null; } }
Android中获取本机ip地址和MAC地址
通过InetAddress.getLocalHost()得到始终是“127.0.0.1”,要想得到真正的网络ip地址要通过下面的方法:
首先新建一个工程,修改AndroidManifest.xml文件增加用户权限,如下:
<uses-permission android:name="android.permission.INTERNET"/> //必写
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/>
<uses-permission android:name="android.permission.CHANGE_NETWORK_STATE"></uses-permission>
<uses-permission android:name="android.permission.ACCESS_WIFI_STATE"></uses-permission>//必写
<uses-permission android:name="android.permission.CHANGE_WIFI_STATE"></uses-permission>
主要函数代码如下:
// 得到本机ip地址 public String getLocalHostIp() { String ipaddress = ""; try { Enumeration<NetworkInterface> en = NetworkInterface .getNetworkInterfaces(); // 遍历所用的网络接口 while (en.hasMoreElements()) { NetworkInterface nif = en.nextElement();// 得到每一个网络接口绑定的所有ip Enumeration<InetAddress> inet = nif.getInetAddresses(); // 遍历每一个接口绑定的所有ip while (inet.hasMoreElements()) { InetAddress ip = inet.nextElement(); if (!ip.isLoopbackAddress() && InetAddressUtils.isIPv4Address(ip .getHostAddress())) { return ipaddress = "本机的ip是" + ":" + ip.getHostAddress(); } } } } catch (SocketException e) { Log.e("feige", "获取本地ip地址失败"); e.printStackTrace(); } return ipaddress; } // 得到本机Mac地址 public String getLocalMac() { String mac = ""; // 获取wifi管理器 WifiManager wifiMng = (WifiManager) getSystemService(Context.WIFI_SERVICE); WifiInfo wifiInfor = wifiMng.getConnectionInfo(); mac = "本机的mac地址是:" + wifiInfor.getMacAddress(); return mac; }
Android 获取wifi的IP地址
WifiManager wifimanage=(WifiManager)context.getSystemService(Context.WIFI_SERVICE);//获取WifiManager //检查wifi是否开启 if(!wifimanage.isWifiEnabled()) { wifimanage.setWifiEnabled(true); } WifiInfo wifiinfo= wifimanage.getConnectionInfo(); String ip=intToIp(wifiinfo.getIpAddress()); //将获取的int转为真正的ip地址,参考的网上的,修改了下 private String intToIp(int i) { return (i & 0xFF)+ "." + ((i >> 8 ) & 0xFF)? + "." + ((i >> 16 ) & 0xFF) +"."+((i >> 24 ) & 0xFF ); }
OK,这样就好了吗?呵呵,别忘记加上权限
<uses -permission="" android:name="android.permission.ACCESS_WIFI_STATE"></uses>
<uses -permission="" android:name="adnroid.permission.CHANGE_WIFI_STATE"></uses>
总结:大家可以对比一下,Android 获取手机 IP 地址的方法,以免在编程的过程中造成不必要的问题.
