Android 获取本机WIFI及3G网络IP
1.获取Wifi地址
```
// 获取本机WIFI
private String getLocalIpAddress() {
WifiManager wifiManager = (WifiManager) getSystemService(WIFI_SERVICE);
WifiInfo wifiInfo = wifiManager.getConnectionInfo();
// 获取32位整型IP地址
int ipAddress = wifiInfo.getIpAddress();
// 返回整型地址转换成“*.*.*.*”地址
return String.format("%d.%d.%d.%d", (ipAddress & 0xff),(ipAddress >> 8 & 0xff),(ipAddress>> 16 & 0xff),(ipAddress >> 24 & 0xff));
}
```
2.获取3G网络地址
```
// 3G网络IP
public static String getIpAddress() {
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()
&& inetAddress instanceof Inet4Address) {
// if (!inetAddress.isLoopbackAddress() && inetAddress
// instanceof Inet6Address) {
return inetAddress.getHostAddress().toString();
}
}
}
} catch (Exception e) {
e.printStackTrace();
}
return null;
}
```
需要添加如下权限：
```
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />
```
