Android :: Get Reference To TabWidget In Java Code

In my layout xml, I have: <TabHost android:id="@+id/tabhost" android:layout_width="fill_parent" android:layout_height="fill_parent">

<TabWidget android:id="@android:id/tabs" android:layout_width="fill_parent" android:layout_height="wrap_content"/>

</TabHost>

My question is how can I get a reference to TabWidget object. I tried this: mTabWidget = (TabWidget) findViewById(com.android.internal.R.id.tabs); but this won't compile since 'com.android.internal.R is not visible. And then I try change the id to android:id="@+id/tabs" but I get a run time error saying: "Your TabHost must have a TabWidget whose id attribute is 'android.R.id.tabs'"
