android - How to find view id in appwidgetprovider?

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.
