有的時候咱們須要得到WIFI的IP地址得到手機網絡的IP地址,這是一個工具類,專門解決這個問題,這裏須要兩個權限:android
<uses-permission android:name="android.permission.ACCESS_WIFI_STATE" > </uses-permission> <uses-permission android:name="android.permission.INTERNET" > </uses-permission>
第一個權限是得到WIFI的IP地址須要使用的,第二個權限是得到移動網絡的IP須要使用的,代碼以下:git
public class GetIPAddressUtil { public static String getWifiIP(Context context) { String ip = null; WifiManager wifiManager = (WifiManager) context .getSystemService(Context.WIFI_SERVICE); if (wifiManager.isWifiEnabled()) { WifiInfo wifiInfo = wifiManager.getConnectionInfo(); int i = wifiInfo.getIpAddress(); ip = (i & 0xFF) + "." + ((i >> 8) & 0xFF) + "." + ((i >> 16) & 0xFF) + "." + (i >> 24 & 0xFF); } return ip; } public static String getMobileIP() { 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("哎呀,出錯了...", ex.toString()); } return null; } }
