I just moved to Fragments a few weeks ago and I've enjoyed allot of
neat benefits like the PageView for my sorting filters on my main
listfragment.
For some reason on my ListFragment when I restartLoader to "requery"
the new data in the Cursor (which is the correct data) and I call
swapCursor on my CursorAdapter with the new data in onLoadFinished,
but for some reason i need to leave the activity or swipe to a new
page in the pageview (sometimes at least 2 pages away) and then return
to see the new updates in the list (like a checked item, or removed
items).
when i swipe to the next page using the pageview it's the same
listfragement (with a different sort) the data is correct.
before I used fragements I was using the cursoradapter and just called
requery as needed. now I have the same cursoradapter, but i also use a
Loader to create and swapCursor on the adapter.
some example of the listfragment code
public void restartLoader()
{
getLoaderManager().restartLoader(0, null, this);
}
//Instantiate and return a new Loader for the given ID.
@Override
public Loader<Cursor> onCreateLoader(int id, Bundle args) {
return new GooTasksLoader(mActivity, this);
}
// Called when a previously created loader has finished its load.
@Override
public void onLoadFinished(Loader<Cursor> loader, Cursor data) {
// Swap the new cursor in. (The framework will take care of
closing
the
// old cursor once we return.)
mAdapter.swapCursor(data);
}
//Called when a previously created loader is being reset, thus making
its data unavailable.
@Override
public void onLoaderReset(Loader<Cursor> loader) {
// This is called when the last Cursor provided to
onLoadFinished()
// above is about to be closed. We need to make sure we are no
// longer using it.
mAdapter.swapCursor(null);
}
