问题 QUESTION: If I set a variable prior to the onCreate can I use notifyDataSetChanged() to update an adapter that uses that array later? I am instigating my city_values array prior to my onCreate -This is the only way I can get the script not to show any errors.

问题 Trying to install MySQL for Python. Two problems: 1) Instructions over the net says installation is python setup.py For me, it results with can't open file 'setup.py': [Errno 2] No such file or directory 2) README.txt says: The Z MySQL database adapter uses the MySQLdb package.
