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。
