Android 获取网络状态的工具类

在工作中我们经常要用到网络，网络状态的检查必不可少，这是一个检查当前网络状态的工具类，直接粘过去就能用：

[java]
package com.todoo.android.app.utils;

import java.net.InetAddress;
import java.net.NetworkInterface;
import java.net.SocketException;
import java.util.Enumeration;

import android.content.Context;
import android.net.ConnectivityManager;
import android.net.NetworkInfo;

public class NetworkUtils
{
    public static final String NET_TYPE_WIFI = "WIFI";
    public static final String NET_TYPE_MOBILE = "MOBILE";
    public static final String NET_TYPE_NO_NETWORK = "no_network";

    private Context mContext = null;

    public NetworkUtils(Context pContext) {
        this.mContext = pContext;
    }

    public static final String IP_DEFAULT = "0.0.0.0";

    public static boolean isConnectInternet(final Context pContext)
    {
        final ConnectivityManager conManager = (ConnectivityManager) pContext.getSystemService(Context.CONNECTIVITY_SERVICE);
        final NetworkInfo networkInfo = conManager.getActiveNetworkInfo();

        if (networkInfo != null)
        {
            return networkInfo.isAvailable();
        }

        return false;
    }

    public static boolean isConnectWifi(final Context pContext) {
        ConnectivityManager mConnectivity = (ConnectivityManager) pContext.getSystemService(Context.CONNECTIVITY_SERVICE);
        NetworkInfo info = mConnectivity.getActiveNetworkInfo();
        //判断网络连接类型，只有在3G或wifi里进行一些数据更新。
        int netType = -1;
        if(info != null){
            netType = info.getType();
        }
        if (netType == ConnectivityManager.TYPE_WIFI) {
            return info.isConnected();
        } else {
            return false;
        }
    }

    public static String getNetTypeName(final int pNetType)
    {
        switch (pNetType)
        {
            case 0:
                return "unknown";
            case 1:
                return "GPRS";
            case 2:
                return "EDGE";
            case 3:
                return "UMTS";
            case 4:
                return "CDMA: Either IS95A or IS95B";
            case 5:
                return "EVDO revision 0";
            case 6:
                return "EVDO revision A";
            case 7:
                return "1xRTT";
            case 8:
                return "HSDPA";
            case 9:
                return "HSUPA";
            case 10:
                return "HSPA";
            case 11:
                return "iDen";
            case 12:
                return "EVDO revision B";
            case 13:
                return "LTE";
            case 14:
                return "eHRPD";
            case 15:
                return "HSPA+";
            default:
                return "unknown";
        }
    }

    public static String getIPAddress()
    {
        try
        {
            final Enumeration<NetworkInterface> networkInterfaceEnumeration = NetworkInterface.getNetwork
