 public boolean isNetworkConnected(Context context) { 
  if (context != null) { 
   ConnectivityManager mConnectivityManager = (ConnectivityManager) context 
     .getSystemService(Context.CONNECTIVITY_SERVICE); 
   NetworkInfo mNetworkInfo = mConnectivityManager.getActiveNetworkInfo(); 
   if (mNetworkInfo != null) { 
    return mNetworkInfo.isAvailable(); 
   } 
  } 
  return false; 
 }

2）判斷WIFI網(wǎng)絡是否可用

 public boolean isWifiConnected(Context context) { 
  if (context != null) { 
   ConnectivityManager mConnectivityManager = (ConnectivityManager) context 
     .getSystemService(Context.CONNECTIVITY_SERVICE); 
   NetworkInfo mWiFiNetworkInfo = mConnectivityManager 
     .getNetworkInfo(ConnectivityManager.TYPE_WIFI); 
   if (mWiFiNetworkInfo != null) { 
    return mWiFiNetworkInfo.isAvailable(); 
   } 
  } 
  return false; 
 }

3）判斷MOBILE網(wǎng)絡是否可用

 public boolean isMobileConnected(Context context) { 
  if (context != null) { 
   ConnectivityManager mConnectivityManager = (ConnectivityManager) context 
     .getSystemService(Context.CONNECTIVITY_SERVICE); 
   NetworkInfo mMobileNetworkInfo = mConnectivityManager 
     .getNetworkInfo(ConnectivityManager.TYPE_MOBILE); 
   if (mMobileNetworkInfo != null) { 
    return mMobileNetworkInfo.isAvailable(); 
   } 
  } 
  return false; 
 }

4）獲取當前網(wǎng)絡連接的類型信息

 public static int getConnectedType(Context context) { 
  if (context != null) { 
   ConnectivityManager mConnectivityManager = (ConnectivityManager) context 
     .getSystemService(Context.CONNECTIVITY_SERVICE); 
   NetworkInfo mNetworkInfo = mConnectivityManager.getActiveNetworkInfo(); 
   if (mNetworkInfo != null && mNetworkInfo.isAvailable()) { 
    return mNetworkInfo.getType(); 
   } 
  } 
  return -1; 
 }
