Question

I have a scrollable ListView with items (like in http://developer.android.com/resources/tutorials/views/hello-listview.html). I am using an ArrayAdapter for the items and use it as a parameter in setListAdapter. Now I would like to add a button at the bottom of the screen, which does not scroll with the list. Could someone give me some hints or post a code snippet how it could possibly be done?

If your activity extends ListActivity then you need something like this:

<LinearLayout android:layout_width="match_parent"
              android:layout_height="match_parent"
              android:orientation="vertical">

    <ListView android:id="@android:id/list"
              android:layout_height="0dip"
              android:layout_width="match_parent"
              android:layout_weight="1" />

    <Button android:id="@+id/btn" 
            android:layout_width="match_parent"
            android:layout_height="wrap_content"/>

</LinearLayout>

Notice that the listview has a layout_weight set to 1. That will keep the button fixed in its place at the bottom.
