Wow, I hadn't expected replies so quickly ! @MagouyaWare - To answer your question, the OnTabChangedListener code rebuilds the listview content. I have indeed stepped through this to ensure that it does this correctly before the first display.
If I call tabhost.setCurrentTab(1) instead of tabhost.setCurrentTab(0), then the initial display is correct. To answer @Mark Murphy (a Commons Guy), when I subsequently click through the tabs, the single listview is correctly updated and displayed. It just doesn't display correctly upon initial display.
