trying again for declarative tabs here --
<!-- contacts_view.xml -->
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android";
android:id="@+id/contacts_view"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
>
<ImageView
android:id="@drawable/masthead_logo"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
/>
<TabHost
android:id="@android:id/tabhost"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_weight="1"
>
<TabWidget
android:id="@android:id/tabs"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
>
<FrameLayout
android:id="@android:id/tabcontent"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
>
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="SHITE"
/>
</FrameLayout>
</TabWidget>
</TabHost>
</LinearLayout>
// ContactsActivity.java (extends TabActivity)
@Override
public void
onCreate (Bundle inSavedInstanceState)
{
super.onCreate (inSavedInstanceState);
setContentView (R.layout.contacts_view);
}
...and the error trace
