            android:layout_width="fill_parent" android:layout_height="wrap_content" />
        <FrameLayout android:id="@android:id/tabcontent"
            android:layout_width="fill_parent" android:layout_height="fill_parent">
            <ListView android:id="@+id/list1" android:layout_width="fill_parent"
                android:layout_height="wrap_content" android:layout_weight="1">
            </ListView>
            <ListView android:id="@+id/list2" android:layout_width="fill_parent"

        </FrameLayout>
    </LinearLayout>
</TabHost>

Remove the layout_weight callout from your listviews (or wrap them in a linearlayout).

As it’s telling you, it’s not valid when the immediate parent layout is a framelayout.
