From what I can gather it appears that this might be because my ListView is not being displayed, I've verified that getCount is returning a value not zero, but I can't see what I'm doing wrong. Everything loads and acts like it's working but the ListView never appears, I put a background color on the fragment reference in mixed.xml and it is there and taking up the full screen, but when I set a background color on my ListView it does not appear, it's like it's not being rendered at all. More odd, getView is not being called in my adapter, and this is all working code from regular activities that I ported to fragments. I've tried calling notifyDataSetChanged which didn't changed anything, debugging shows the adapter is filled with data and getCount is indeed returning an accurate count greater than 0. Thanks for any help, I'm stuck. Project is open and can be viewed here <a href="http://code.google.com/p/shack-droid/source/browse/#svn%2FTrunk" rel="nofollow">http://code.google.com/p/shack-droid/source/browse/#svn%2FTrunk</a> but I'm also including the pertinent code here. This is the ListFragment: <pre><code> public class FragmentTopicView extends ListFragment implements ShackGestureEvent { private ArrayList<ShackPost> posts; private String storyID = null; private String errorText = ""; private Integer currentPage = 1; private Integer storyPages = 1; private String loadStoryID = null; private Boolean threadLoaded = true; private Hashtable<String, String> postCounts = null; private AdapterLimerifficTopic tva; public FragmentTopicView() { } @Override public void onCreate(Bundle savedInstanceState) { // TODO Auto-generated method stub super.onCreate(savedInstanceState); this.setRetainInstance(true); } @Override public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { return

onScroll(AbsListView view, int firstVisibleItem, int visibleItemCount, int totalItemCount) { // start loading the next page if (threadLoaded && firstVisibleItem + visibleItemCount >= totalItemCount &&

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
