    <p>Write an adapter for your list items and add a method to append new results</p> <pre><code>public class JsonListAdapter extends BaseAdapter { private List&lt;JSONObject&gt; list; public void appendList(List&lt;JSONObject&gt;pList) { if (list== null) { list= new List&lt;JSONObject&gt;(); } if (pList != null) { list.addAll(pList); notifyDataSetChanged(); } } ... } </code></pre> <p>Add a scroll listener to start the paging request</p> <pre><code>private class PagingScrollListener implements OnScrollListener { private int lastOffset = 0; @Override public void onScroll(AbsListView view, int firstVisibleItem, int visibleItemCount, int totalItemCount) { boolean isEndOfListReached = firstVisibleItem + visibleItemCount &gt;= totalItemCount; boolean isOffsetRequested = lastOffset &gt;= totalItemCount; if (isEndOfListReached &amp;&amp; !isOffsetRequested) { lastOffset = totalItemCount; new PagingRequest(myListAdapter).execute(lastOffset); } } ... } </code></pre> <p>Load next batch of data and update the adapter:</p> <pre><code>private static class PagingRequest extends AsyncTask&lt;Integer, Void, List&lt;JSONObject&gt; { private JsonListAdapter mAdapter; public PagingRequest(JsonListAdapter adapter) { this.mAdapter = adapter; } protected ProductList doInBackground(Integer... params) { int offset = params[0]; // PERFORM REQUEST WITH OFFSET return newResults; } protected void onPostExecute(List&lt;JSONObject&gt; result) { mAdapter.appendList(result); } } </code></pre> <p>Disclaimer: This is just the basic strategy, you still need to fill in the blanks and adapt to your code.</p>

    1. COThanks for that but I was looking for a complete example - i.e. a eclipse project - many claim to do this but either don't use JSON data OR do but don't implement the "load more" link at the bottom of the listview they just load all the JSON data, and if you have 10,000 rows that's a lot to swallow...

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.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
