    <p>I'm getting some very jerky scrolling while using the code below to create a ListView from a Cursor. Is there something I'm doing wrong, or any way to improve the performance of this ListView? </p> <pre><code>bookmarksListView = (ListView)findViewById(R.id.bookmarks_listview); bookmarksDbCursor = bookmarkStore.getCursor(); startManagingCursor(bookmarksDbCursor); String[] bookmarksColumns = new String[3]; bookmarksColumns[0] = "TITLE"; bookmarksColumns[1] = "URL"; bookmarksColumns[2] = "ICONID"; int[] bookmarksViews = new int[3]; bookmarksViews[0] = R.id.title_text; bookmarksViews[1] = R.id.subtitle_text; bookmarksViews[2] = R.id.icon_view; bookmarksListAdapter = new SimpleCursorAdapter(this, R.layout.list_item, bookmarksDbCursor, bookmarksColumns, bookmarksViews); bookmarksListView.setAdapter(bookmarksListAdapter); bookmarksListView.setOnItemClickListener(new OnItemClickListener() { @Override public void onItemClick(AdapterView&lt;?&gt; parent, View view, int position, long id) { Toast.makeText(BookmarkHistoryTabActivity.this, "Clicked ID " + Long.toString(id), Toast.LENGTH_SHORT).show(); } }); registerForContextMenu(bookmarksListView); </code></pre> <p>Note: <code>bookmarkStore.getCursor()</code> returns an unmanaged cursor from a sqlite database containing the columns from <code>bookmarksColumns</code>.</p> <p>The icons I'm loading (from R.drawable) aren't the issue - I've tried turning them off and it has no effect. I've encountered a similar scrolling issue with a custom ListAdapter extending BaseAdapter I wrote a while ago, and it was caused by not properly setting the view's values in getView() I resolved it using the fix posted at <a href="https://stackoverflow.com/questions/1320478/how-to-load-the-listview-s">How to load the Listview &quot;smoothly&quot; in android</a>..., but that was for a custom adapter class, and I'm not really sure how to implement that fix when I'm using a stock SimpleCursorAdapter, or if that fix even applies to this situation. </p> <p>EDIT: The query returning info on the database looks like this, in case that helps:</p> <pre><code>public Cursor getCursor() { openDB(); Cursor c = mDB.query(DB_TABLENAME, new String[]{"_id", "ICONID", "DATE", "TITLE", "URL"}, null, null, null, null,"DATE DESC"); return c; } </code></pre> <p>EDIT2: I have no idea why, but this behavior only occurs in android 1.6+ I've tried changing my query, removing the sorting, etc. for my cursor, nothing seems to help. The database is very small (&lt;20 items) and only contains the columns present in the query above.</p>

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.
