首先在AndroidManifest.xml添加許可權

<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />

1,判斷是否有網路連接

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網路是否可用

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網路是否可用

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.判斷網路類型

            //傳回值 -1：沒有網路  1：WIFI網路2：wap網路3：net網路    public static int GetNetype(Context context)    {         int netType = -1;          ConnectivityManager connMgr = (ConnectivityManager) context.getSystemService(Context.CONNECTIVITY_SERVICE);         NetworkInfo networkInfo = connMgr.getActiveNetworkInfo();         if(networkInfo==null)        {             return netType;         }         int nType = networkInfo.getType();         if(nType==ConnectivityManager.TYPE_MOBILE)        {             if(networkInfo.getExtraInfo().toLowerCase().equals("cmnet"))            {                 netType = 3;             }             else            {                 netType = 2;             }         }         else if(nType==ConnectivityManager.TYPE_WIFI)        {             netType = 1;         }         return netType;     }
