1.使用WIFI
首先设置用户权限
复制代码代码如下:
<uses-permission android:name="android.permission.INTERNET"></uses-permission> <uses-permission android:name="android.permission.ACCESS_WIFI_STATE"></uses-permission> <uses-permission android:name="android.permission.CHANGE_WIFI_STATE"></uses-permission> <uses-permission android:name="android.permission.WAKE_LOCK"></uses-permission>
1:获取wifi地址
public class NetWorkUtils { /** * 检查网络是否可用 * * @param paramContext * @return */ public static boolean checkEnableContext 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 int2ipint ipInt) { StringBuilder sb = new StringBuilder); sb.appendipInt & 0xFF).append"."); sb.appendipInt >> 8) & 0xFF).append"."); sb.appendipInt >> 16) & 0xFF).append"."); sb.appendipInt >> 24) & 0xFF); return sb.toString); } /** * 获取当前ip地址 * * @param context * @return */ public static String getLocalIpAddressContext context) { try { WifiManager wifiManager = WifiManager) context .getSystemServiceContext.WIFI_SERVICE); WifiInfo wifiInfo = wifiManager.getConnectionInfo); int i = wifiInfo.getIpAddress); return int2ipi); } catch Exception ex) { return " 获取IP出错鸟!!!!请保证是WIFI,或者请重新打开网络! " + ex.getMessage); } // return null; } }
//GPRS连接下的ip public 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 ex) { Log.e"WifiPreference IpAddress", ex.toString)); } return null; }
