One more question on this - it seems like if we use a header or footer
view - then our activity can not add any other views? Example:
<LinearLayout>
<ListView> // with header and footer views.
</LinearLayout>
the above works perfectly with focus getting routed correctly etc. The
focus acts strangely in this case though:
<LinearLayout>
<LinearLayout>
<Button>
</LinearLayout>
<ListView>
</LinearLayout>
if the list view has focusable items - then the focus jumps back up to
the top LinearLayout-button after hitting down key again. This is kind
of strange, should this be happening? To explain further:
<LinearLayout>
<LinearLayout>
<Button>
</LinearLayout>
<ListView>
// listview is composed of:
TextView
TextView
Button
TextView
</ListView>
</LinearLayout>
so focus is fine up until it hits the row with the Button. The button
gets highlighted (since itemsCanFocus=true), but then hitting the down
arrow key again jumps focus up to the top linear layout button,
instead of continuing focus to the next row of the ListView. Normally
I could just use a header view instead, but is there an undocumented
rule in which we cannot add other views to our layout if using a
ListView with setItemsCanFocus=true?
Thanks
