Android 获取自身IP

Android处于网络连接状态，获取自身IP。

package wifi.localinfo;

import java.net.InetAddress;
import java.net.NetworkInterface;
import java.net.SocketException;
import java.util.Enumeration;
import org.apache.http.conn.util.InetAddressUtils;

public class GetLocalIp {  
	   
	public static String getLocalIp()
    {
        String ipaddress = "";
        try
        {
            Enumeration<NetworkInterface> en = NetworkInterface
                    .getNetworkInterfaces();
            // 遍历所用的网络接口
            while (en.hasMoreElements())
            {
            	// 得到每一个网络接口绑定的所有ip
                NetworkInterface nif = en.nextElement();
                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()))
                    {
                        ipaddress = ip.getHostAddress();
                        return ipaddress;
                    }
                }
            }
        }
        catch (SocketException e)
        {
            e.printStackTrace();
        }
        return ipaddress;

    }
}  

Android配置权限

    <uses-permission android:name="android.permission.CHANGE_NETWORK_STATE" />
    <uses-permission android:name="android.permission.CHANGE_WIFI_STATE" />
    <uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />
    <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
