请试试这个。希望对您有所帮助。

public static int TYPE_WIFI = 1;
public static int TYPE_MOBILE = 2;
public static int TYPE_NOT_CONNECTED = 0;


public static int getConnectivityStatus(Context context) {
    ConnectivityManager cm = (ConnectivityManager) context
            .getSystemService(Context.CONNECTIVITY_SERVICE);

    NetworkInfo activeNetwork = cm.getActiveNetworkInfo();
    if (null != activeNetwork) {
        if(activeNetwork.getType() == ConnectivityManager.TYPE_WIFI)
            return TYPE_WIFI; 

        if(activeNetwork.getType() == ConnectivityManager.TYPE_MOBILE)
            return TYPE_MOBILE;
    } 
    return TYPE_NOT_CONNECTED;
}

public static String getConnectivityStatusString(Context context) {
    int conn = NetworkUtil.getConnectivityStatus(context);
    String status = null;
    if (conn == NetworkUtil.TYPE_WIFI) {
        status = "Wifi enabled";
    } else if (conn == NetworkUtil.TYPE_MOBILE) {
        status = "Mobile data enabled";
    } else if (conn == NetworkUtil.TYPE_NOT_CONNECTED) {
        status = "Not connected to Internet";
    }
    return status;
}
