You also need android:layout_weight="1". Something like this:
the adapter

For CursorAdapter, requery() the underlying Cursor, and it will
automatically update the UI.

That's a bit complicated for what you're describing, but

But you really should consider stopping the thread in onPause() and

Beyond that, there are three XML parsers in Android: DOM, SAX, and the
aforementi
er.deserialize(BeanA.class);
> List listOfBeanB=
> (List)xmlDeserializer.deserialize(BeanB.class);
First, don't do it that way. Make exactly ONE pass through the XML, not
several.
If you wish to make several passes anyway, get a fresh XmlPullParser
before doing the second bean.
