Getting a CastClassException error in the onListItemClick method of a ListFragment-Collection of common programming errors

I have a class that extends ListFragment and I’m using the Support Library. In the class’s onListItemClick method, I have this line:

@Override
public void onListItemClick(ListView l, View v, int position, long id) {
    String item = (String) ((Fragment) getListAdapter().getItem(position)).getString(1);
    DetailFrag frag = (DetailFrag) getFragmentManager().findFragmentById(R.id.frag_stitchdetail);
    if (frag != null && frag.isInLayout()) {
        frag.setText(item);
    }
}

where position is a parameter that is passed to the onListItemClick method. Its value at runtime is 0 for the example app I’m building, as there’s only one item in the list. This line throws the following error:

java.lang.CastClassException: android.content.ContentResolver$CursorWrapperInner cannot be cast to java.lang.String

I’ve Googled this and searched on stackoverflow, but I don’t see anything that will give me a hint as to why I can’t cast this to a String. Anyone know? Thanks!

My ContentProvider code for the query:

@Override
public Cursor query(Uri uri, String[] projection, String selection,
        String[] selectionArgs, String sortOrder) {
    SQLiteQueryBuilder queryBuilder = new SQLiteQueryBuilder();
    queryBuilder.setTables(STITCHTABLE_BASEPATH);
    int uriType = sURIMatcher.match(uri);
    switch (uriType)
    {
    case STITCHES_ID:
        queryBuilder.appendWhere(SQLData.KEY_ROWID + "=" + uri.getLastPathSegment());
        break;
    case STITCHES:
        //no filter
        break;
    default:
        throw new IllegalArgumentException("Unknown URI");
    }
    Cursor cursor = queryBuilder.query(mDB.getReadableDatabase(), projection, selection, selectionArgs, null, null, sortOrder);
    cursor.setNotificationUri(getContext().getContentResolver(), uri);
    return cursor;
}

The code in my ListFragment for the CursorLoader:

@Override
public void onActivityCreated(Bundle savedInstanceState) {
    super.onActivityCreated(savedInstanceState);

    Intent myData = getActivity().getIntent();
    Bundle info = myData.getExtras();

    String[] dataColumns = { "stitchname" };
    int[] viewIDs = { R.id.stitchlist1 };
    mAdapter = new SimpleCursorAdapter(getActivity(), R.layout.stitchlist, null, dataColumns, viewIDs, 0);
    setListAdapter(mAdapter);
    getLoaderManager().initLoader(0, info, (LoaderCallbacks) this); 

}
@Override
public Loader onCreateLoader(int id, Bundle args) {
    String selection = "stitchlevel=?";
    String[] selectionArgs = new String[] {args.getString("Level")};
    return (Loader) new CursorLoader(getActivity(), STITCHES_URI,
            PROJECTION, selection, selectionArgs, null);    
}
@Override
public void onLoadFinished(Loader loader, Cursor cursor) {
        mAdapter.swapCursor((android.database.Cursor) cursor);      
}
