how to communicate with embedded activity

In my current project I have a full screen TabActivity. Each tab content is handled by two instances of same ListActivity. Now, I put an extra int in intent to know which data should be displaye开发者_Python百科d. So in onCreate() method of my ListActivity, I check the int in extra and I build my query to obtain a SQLLiteCursor.

I would like to dynamycally give to this two instances of ListActivity the list of item that should be displayed.

I do not know what is the best way to do this. Any idea ?

Regards,

Why not just use ListViews as the contents of the tabs? Why make your job so much harder by wrapping those ListViews each in a ListActivity, then having to work around the fact that you wrapped each in a ListActivity?

Get rid of the ListActivity classes. Put two ListViews as the contents of your tabs. Hand the Adapters to those ListViews in your TabActivity (or regular activity that is using a TabHost).
