Android - view tag isn't correct on view:null (CursorAdapter and DataBinding)

Question

So yesterday I have finally found some time to try new DataBinding library. I have tried to use it with CursorAdapter but with no success.

As Androidguys written on

Answer 1

Based on Android developers video about databinding It looks like ItemBinding is set as tag for view (in their case it is passed inside ViewHolder) and retrieved later. Thats where I found idea to find binding inside views:

So the Solution is:

private class BookCursorAdapter extends CursorAdapter {

    ...

    @Override
    public View newView(Context context, Cursor cursor, ViewGroup parent) {
        BookListItemBinding binding = BookListItemBinding.inflate(getLayoutInflater(), parent, false);
        return binding.getRoot();
    }

    @Override
    public void bindView(View view, Context context, Cursor cursor) {
        Book book = new Book(cursor);
        BookListItemBinding binding = DataBindingUtil.getBinding(view);
        binding.setBook(book);
    }

}
