Table not updating with multiple textviews in item_card

Hello,
I've wanted to display a table with 4 TextViews per item, but the table isn't getting updated when I use my modified version of EditItemDialog(to support the 4 TVs I mentioned above).
The data in the csv gets updated immediately, also if I switch to another fragment and back to the table-fragment, the data's displayed correctly!

How can I fix that?

Code handling EditItemDialog response(GH is bugging...):

`

@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == EditItemDialog.REQUEST_CODE_EDIT_ITEM && resultCode == Activity.RESULT_OK && data != null) {
int columnIndex = data.getIntExtra(EditItemDialog.EXTRA_COLUMN_NUMBER, 0);
int rowIndex = data.getIntExtra(EditItemDialog.EXTRA_ROW_NUMBER, 0);
String s = data.getStringExtra(EditItemDialog.EXTRA_SUBJECT);
String t = data.getStringExtra(EditItemDialog.EXTRA_TEACHER);
String r = data.getStringExtra(EditItemDialog.EXTRA_ROOM);

// My attempts to update the layout:
mCsvFileDataSource.updateItem(rowIndex, columnIndex,
CsvFileDataSourceImpl.prepItem(s, t, r));
mTableAdapter.notifyItemChanged(rowIndex, columnIndex);
mTableLayout.notifyItemChanged(rowIndex, columnIndex);
mCsvFileDataSource.applyChanges(getLoaderManager(),
mTableLayout.getLinkedAdapterRowsModifications(),
mTableLayout.getLinkedAdapterColumnsModifications(),
mTableLayout.isSolidRowHeader(),
ScheduleFragment.this);
mTableLayout.setVisibility(View.GONE);
mTableLayout.setVisibility(View.VISIBLE);
//mTableLayout.invalidate();
onFileUpdated(StorageUtils.getScheduleFile(getActivity()).getAbsolutePath(), true); // .getScheduleFile() returns File object
}
}
`

`

public static String prepItem(String s, String t, String r) {
return s + ";" + t + ";" + r;
}

//...

public String getItemData(int rowIndex, int columnIndex, int position) { // helper method for schedule, splits item and returns data at position's index
try {
List rowList = getRow(rowIndex);
return (rowList == null ? "" : rowList.get(columnIndex)).split(";")[position];
} catch (Exception e) {
Log.e(TAG, "get rowIndex=" + rowIndex + "; colIndex=" + columnIndex + "; position:" + position + "\ncache = " +
mItemsCache.toString(), e);
return null;
}
}
`

Best regards,
Felipe

PS: Except for above issue, it works like a charm!

Start by tracing onActivityResult in the schedule fragment, including the calls to mTableAdapter, mTableLayout, and onFileUpdated, then inspect how getItemData splits the updated CSV value for the four TextViews. Done means an edited item refreshes all displayed TextViews immediately without switching fragments, while the CSV data remains updated.
