Just a few questions:
- What kind of Lists are you speaking of List, ListView or both?
- Do you really need a second Activity to display the Tabs ?
You could use several Panels in the same Avtivity to do that:
- a main panel to select the vegetable.
- a second panel with the TabHost
- 1 layout file for each panel
- 1 layout file for each tab
In the layout files for the tabs you add a ListView, and you access it with it's name.
Could you post the project you have already written, I could have a look at it.
You could also have a look at
this example. It's not exactly what you need but could be interesting. It has an activity with a TabHost with 2 Tabs and a ScrollView on each. The ScrollViews are added by code but could also be added in the Designer. The ScrollViews could be replaced by ListViews.
Best regards.
