问题
I have a appwidget extends from appwidgetprovider.
I have created a layout xml file named main_layout.xml and add a button. If i develop a listActivity i reach this button with this path: R.layout.main_layout.button01.
(Button)findViewById(R.layout.main_layout.button01)
Activity class has a member method that named findViewById() but appwidgetprovider has not.
How can i reach my button in my layout?
sorry for my english

You can never reference or modify views in Appwidget directly. You should do this in RemoteViews.
