Body
<p>You should set onScrollListener in your list and keep a track of the visibility of the items and the offset. I show you an example here:</p> <pre><code>// Adapter for the custom list adapter = new Adapter(this, activityList); setListAdapter(adapter); registerForContextMenu(getListView()); getListView().setOnScrollListener(new OnScrollListener(){ public void onScroll(AbsListView lw, final int firstVisibleItem, final int visibleItemCount, final int totalItemCount) { switch(lw.getId()) { case android.R.id.list: // Make your calculation stuff here. You have all your // needed info from the parameters of this function. // Sample calculation to determine if the last // item is fully visible. final int lastItem = firstVisibleItem + visibleItemCount; if(lastItem == totalItemCount) { // Last item is fully visible. Log.i("a", "last item fully visible..."); try { if(offset > 0){ int newLimit; int oldOffset = offset; if(offset >= limit){ newLimit = limit; offset = offset - limit; } else{ newLimit = length; offset = 0; } for (int i=0; i < newLimit; i++) { JSONObject item = jFeed.getJSONObject(i + length - oldOffset); // Pulling items from the array // Get list info String sInfo = item.getString(TAG_INFO); Log.i(MainActivity.class.getName(), "Info: " + sInfo); // Populate the dynamic custom list HashMap<String, String> map = new HashMap<String, String>(); map.put(KEY_INFO, sInfo); activityList.add(map); } adapter.notifyDataSetChanged(); } catch (JSONException e) { // TODO Auto-generated catch block e.printStackTrace(); } } } } public void onScrollStateChanged(AbsListView view, int scrollState) { // TODO Auto-generated method stub if(scrollState == 0) Log.i("a", "scrolling stopped..."); } }); </code></pre>

Guidance

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.
