    <p>I am trying to do the following</p> <pre><code>1) Activity with a List view 2) Talks to content ContentProvider 3) Populates the ListView with contents of Cursor 4) User can then add new items to database 5) After each item is added I want to refresh the list view to show the updated items. </code></pre> <p>Everything upto point 5 works.</p> <p>So I need help with restarting the Loader after the item has been added.</p> <p>So after the data has been added to the database I am calling:</p> <blockquote> <p><code>getLoaderManager().restartLoader(ID, null, MyFragment.this);</code></p> </blockquote> <p>And in the Loader methods I simply do:</p> <pre><code>@Override public Loader&lt;Cursor&gt; onCreateLoader(int id, Bundle args) { Log.w(TAG, "onCreateLoader"); cursorLoader = new CursorLoader(getActivity(), MyContract.CONTENT_URI, null, null, null, "_id ASC"); return cursorLoader; } @Override public void onLoadFinished(Loader&lt;Cursor&gt; loader, Cursor cursor) { adapter.swapCursor(cursor); //swap the new cursor in. } @Override public void onLoaderReset(Loader&lt;Cursor&gt; loader) { adapter.swapCursor(null); } </code></pre> <p>When this is called, the ListView blanks out. All previous items in the list disappear.</p> <p>If I go out of my activity and back into again the SimpleCursorAdapter will populate the ListView with the added items in the database. </p> <p>So I know they have been added correctly.</p> <p>But it is not displaying after I call restartLoader.</p> <p>Does anyone know how I can refresh the listView using the Loader ?</p> <p>Should I call something after </p> <pre><code>getLoaderManager().restartLoader(1, null, MyFragment.this);` </code></pre> <p>Or do I need to something more clever in onLoaderReset method ?</p> <p>Any tips and pointers please ?</p> <p>Thanks !!!</p>

    3. COno, you have to use a Loader, the point is to create a ContentProvider that notifies about any changes done inside

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.
