Is there a way to restrict the number of items in a Column after drag and drop. Like if i want only 5 items in a column and if i drag a 6th item column should lock

Hello Jake,

I would like to achive the same scroll as in Trello (video: https://youtu.be/fca9Uymwnsg). Scroll by one column. Please give me a suggestion how to achive this scroll with your library.

Best regards,
Vlad.

Scroll listener for pagination in column list. Please

I can't change maxItemCount, i don't how overwrite maxItemCount

I am using boardview to implement Kanban board . Everything is working fine .There is one issue .
Follow these steps to reproduce that bug:

• Add lot of data more than 50 cards in each Vertical List of Boardview
• Scroll the list so that pick some card in middle or nearest to those 50 cards .
• When you pick the card than it will not show (hidden or location is somewhere else)while the functionality working fine after dropping the card
  Can you help me to fix this issue ?

Hi,

I am working on a project at Universideda Federal Rural de Pernambuco (UFRPE) in Brazil. My team needs a kanban board for an android app and yours seems to be the best choice. Although, while studying your API, I realised that it'll be necessery to make some programming changes to work the way our project needs it to be.
Is your API open source ? Moreover, can I have access to your code?

Our idea is to improve the layout of the board and its cards and if we manage to do it we can send it to you to collaborate with your work.

Thanks for your time,
Best Regards.

Hi. I've noticed when logging endDrag that startItemPos shows the column position, and startColumnPos shows the Item position. So in that sense, they're twisted. My temporary workaround was to switch the order like this :

@Override
            public void endDrag(View view, int startColumnPos, int startItemPos, int endItemPos, int endColumnPos) {...}

Both startDrag and endDrag are affected. changedPosition seems ok
Also endItemPos and endColumnPos are ok. Only start positions are affected
