Android判断是Wifi还是4G网络代码

本文实例为大家分享了android判断是wifi还是4g网络的具体代码，供大家参考，具体内容如下

package com.chengxinet.bobo.utils;

import android.content.context;
import android.net.connectivitymanager;
import android.net.networkinfo;
import android.telephony.telephonymanager;

/**
 * created by administrator on 2016/1/7.
 */
public class networkutils {
  public static boolean isnetworkavailable(context c) {
    context context = c.getapplicationcontext();
    // 获取手机所有连接管理对象（包括对wi-fi,net等连接的管理）
    connectivitymanager connectivitymanager = (connectivitymanager) context.getsystemservice(context.connectivity_service);

    if (connectivitymanager == null) {
      return false;
    } else {
      // 获取networkinfo对象
      networkinfo[] networkinfo = connectivitymanager.getallnetworkinfo();

      if (networkinfo != null && networkinfo.length > 0) {
        for (networkinfo anetworkinfo : networkinfo) {
//          system.out.println(i + "===状态===" + networkinfo[i].getstate());
//          system.out.println(i + "===类型===" + networkinfo[i].gettypename());
          // 判断当前网络状态是否为连接状态
          if (anetworkinfo.getstate() == networkinfo.state.connected) {
            return true;
          }
        }
      }
    }
    return false;
  }

  /**
   * 判断wifi是否打开
   * @param context
   * @return
   */
  public static boolean iswifienabled(context context) {
    connectivitymanager mgrconn = (connectivitymanager) context
        .getsystemservice(context.connectivity_service);
    telephonymanager mgrtel = (telephonymanager) context
        .getsystemservice(context.telephony_service);
    return ((mgrconn.getactivenetworkinfo() != null && mgrconn
        .getactivenetworkinfo().getstate() == networkinfo.state.connected) || mgrtel
        .getnetworktype() == telephonymanager.network_type_umts);
  }

  /**
   * 判断是否是3g网络
   * @param context
   * @return
   */
  public static boolean is3rd(context context) {
    connectivitymanager cm = (connectivitymanager) context
        .getsystemservice(context.connectivity_service);
    networkinfo networkinfo = cm.getactivenetworkinfo();
    if (networkinfo != null
        && networkinfo.gettype() == connectivitymanager.type_mobile) {
      return true;
    }
    return false;
  }

  /**
   * 判断是wifi还是3g网络
   * @param context
   * @return
   */
  public static boolean iswifi(context context) {
    connectivitymanager cm = (connectivitymanager) context
        .getsystemservice(context.connectivity_service);
    networkinfo networkinfo = cm.getactivenetworkinfo();
    if (networkinfo != null
        && networkinfo.gettype() == connectivitymanager.type_wifi) {
      return true;
    }
    return false;
  }
}
