Android获取本机ip和外网IP

本机IP：

/** * 获取ip地址 * @return */ public static String getHostIP() { String hostIp = null; try { Enumeration nis = NetworkInterface.getNetworkInterfaces(); InetAddress ia = null; while (nis.hasMoreElements()) { NetworkInterface ni = (NetworkInterface) nis.nextElement(); Enumeration<InetAddress> ias = ni.getInetAddresses(); while (ias.hasMoreElements()) { ia = ias.nextElement(); if (ia instanceof Inet6Address) { continue;// skip ipv6 } String ip = ia.getHostAddress(); if (!"127.0.0.1".equals(ip)) { hostIp = ia.getHostAddress(); break; } } } } catch (SocketException e) { Log.i("yao", "SocketException"); e.printStackTrace(); } return hostIp; }

外网IP:

/** * 获取IP地址 * @return */ public static String GetNetIp() { URL infoUrl = null; InputStream inStream = null; String line = ""; try { infoUrl = new URL("http://pv.sohu.com/cityjson?ie=utf-8"); URLConnection connection = infoUrl.openConnection(); HttpURLConnection httpConnection = (HttpURLConnection) connection; int responseCode = httpConnection.getResponseCode(); if (responseCode == HttpURLConnection.HTTP_OK) { inStream = httpConnection.getInputStream(); BufferedReader reader = new BufferedReader(new InputStreamReader(inStream, "utf-8")); StringBuilder strber = new StringBuilder(); while ((line = reader.readLine()) != null) strber.append(line + "\n"); inStream.close(); // 从反馈的结果中提取出IP地址 int start = strber.indexOf("{"); int end = strber.indexOf("}"); String json = strber.substring(start, end + 1); if (json != null) { try { JSONObject jsonObject = new JSONObject(json); line = jsonObject.optString("cip"); } catch (JSONException e) { e.printStackTrace(); } } return line; } } catch (MalformedURLException e) { e.printStackTrace(); } catch (IOException e) { e.printStackTrace(); } return line; }
