Android检查手机网络状态及网络类型的方法

本文实例讲述了android检查手机网络状态及网络类型的方法。分享给大家供大家参考。具体分析如下：

//judge network status is connecting or not
 public static boolean checknetworkconnected(context context) { 
 if (null!=context) { 
 connectivitymanager connectivitymanager = (connectivitymanager) context
 .getsystemservice(context.connectivity_service); 
 networkinfo networkinfo = connectivitymanager.getactivenetworkinfo();
 if (null!=networkinfo) { 
  return networkinfo.isavailable(); 
  } 
 } 
  return false; 
 } 
 //judge wifi status is connecting or not
 public static boolean checkwifistatus(context context) { 
 connectivitymanager connectivitymanager = (connectivitymanager) context 
 .getsystemservice(context.connectivity_service); 
 networkinfo networkinfo = connectivitymanager.getactivenetworkinfo(); 
 if (null!=networkinfo 
 && networkinfo.gettype() == connectivitymanager.type_wifi) { 
 return true; 
  } 
 return false; 
 } 
 //judge 3g status is connecting or not
 public static boolean check3gstatus(context context) { 
 connectivitymanager connectivitymanager = (connectivitymanager) context 
 .getsystemservice(context.connectivity_service); 
 networkinfo networkinfo = connectivitymanager.getactivenetworkinfo(); 
 if (null!=networkinfo 
 && networkinfo.gettype() == connectivitymanager.type_mobile) { 
 return true; 
  }
 return false; 
 }

希望本文所述对大家的android程序设计有所帮助。
