Sectioned ListView and ExpandableListView

Question

Hi all, I need to create a layout with a title bar on the top and a list view with n sections. The list header of every section has got two distinct Buttons that must be clickable and focusable independently from each other. This is the code of the layout:

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent" android:layout_height="wrap_content"
    android:orientation="vertical">

    <include layout="@layout/title_bar" />

    <ListView android:id="@android:id/list" 
      android:layout_width="fill_parent"
      android:layout_height="0dip" 
      android:layout_weight="1.0"   
    />
</LinearLayout>

I tried this two solutions but I've found issues that I am not able to solve in both:

1) Using a sectioned adapter (source code can be found here). It works fine without the title bar but with the title bar the default focus algorithm doesn't work any more.
2) Using an ExpandableListAdapter (in this case obviously the ListView in the layout becomes an ExpandableListView). It works fine but if I press the dpad center button on group layout both buttons are clicked. I did not find a way to solve this.

Anyone can help?

Thanks very much!
