"Using ListActivity & ExpandableListActivity at the same in one tab
activity."
is just an example of crash in tabs.
The crash still happens when you use ListView and ExpandableListView
as the contents of the tabs, not activities.
Another example here. (I modified tabs1.xml from ApiDemos.)
<ListView android:id="@+id/view1"
android:layout_width="fill_parent"
android:layout_height="fill_parent"/>
<LinearLayout android:id="@+id/view2"
android:background="@drawable/red"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<ListView android:id="@android:id/list"
android:layout_width="fill_parent"
android:layout_height="fill_parent"/>
</LinearLayout>
<LinearLayout android:id="@+id/view3"
android:background="@drawable/blue"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<ExpandableListView android:id="@android:id/list"
android:background="@drawable/green"
android:layout_width="fill_parent"
android:layout_height="fill_parent"/>
</LinearLayout>
