copied!<p>I think SwipeToDismissUndoList is not good for cursor-based adapters. Because the adapters rely on changes from content providers (<a href="http://developer.android.com/reference/android/database/Cursor.html#setNotificationUri%28android.content.ContentResolver,%20android.net.Uri%29" rel="nofollow"><code>setNotificationUri()</code></a> or <a href="http://developer.android.com/reference/android/database/Cursor.html#registerContentObserver%28android.database.ContentObserver%29" rel="nofollow"><code>registerContentObserver()</code></a>…) to update UI. You don't know when the data is available or not. That's the problem you're facing.</p> <p>I think there is something like a trick. You can use <a href="http://developer.android.com/reference/android/database/MatrixCursor.html" rel="nofollow"><code>MatrixCursor</code></a>.</p> <ul> <li>In <a href="http://developer.android.com/reference/android/app/LoaderManager.LoaderCallbacks.html#onLoadFinished%28android.content.Loader%3cD%3e,%20D%29" rel="nofollow"><code>onLoadFinished(Loader, Cursor)</code></a>, you keep a reference to the cursor returned from content provider. You need to close it manually later.</li> <li>In <code>SwipeDismissList.OnDismissCallback.onDismiss()</code>, create new <code>MatrixCursor</code>, copy all items from the current cursor <em>except</em> the items that are being removed.</li> <li>Set the newly created matrix cursor to the adapter with <a href="http://developer.android.com/reference/android/widget/CursorAdapter.html#swapCursor%28android.database.Cursor%29" rel="nofollow"><code>swapCursor()</code></a> (<em>not</em> <code>changeCursor()</code>). Because <code>swapCursor()</code> doesn't close the old cursor. You need to keep it open so the loader works properly.</li> <li>Now the UI is updated, you make a call to <code>getContentResolver().delete()</code> and actually remove the items that the user wanted to remove. When the content provider finishes deleting data, it notifies the original cursor to reload data.</li> <li><p>Make sure to close the original cursor that you swapped. For example:</p> <pre><code>private Cursor mOrgCursor; @Override public void onLoadFinished(Loader<Cursor> loader, Cursor data) { if (mOrgCursor != null) mOrgCursor.close(); mOrgCursor = data; mAdapter.changeCursor(mOrgCursor); } @Override public void onLoaderReset(Loader<Cursor> loader) { if (mOrgCursor != null) { mOrgCursor.close(); mOrgCursor = null; } mAdapter.changeCursor(null); } </code></pre></li> <li>Don't worry about the matrix cursor, <code>changeCursor()</code> will close it.</li> </ul>
