View recycling about sortabletableview

[ISchwarz23]

Hi @ciskeboekelo,

no, there is no explicit reason. I have created this library for a project where the amount of data was pretty small. But I can see the issue if the amount of data is growing. I'm thinking about a new TableDataAdapter which makes use of the recycler view pattern.

Hi @ISchwarz23 ,
Thanks for such a great library.
Could you please do the recycling and update the library or is there any way I can do it?

Hi @rohitjagtap1991,

I'm glad that you like my library :)

As the core component of the tableview is a ListView and not a RecyclerView it would be a complete recreation of this library to have the 'original' Android RecyclerView in place.

If we want to hava the same concept as the recycler view in the ListView we need to have a LayoutManager that manages the adding of views that are on the screen and remove them from the list if they are off the screen (so they can be recycled with different data on a different position).

But what can be done to improve the performance (but which will consume more memory) is to create a TableDataAdapter that will cache the views, instead of creating them for every call. In this case you also need to invalidate this cache as soon as the data changed.

But in deed, the proper solution would be, to replace the ListView by a RecyclerView using a LinearLayoutManager. As this will change a main part of the TableView API there will not do this change in the near future in this library. Another idea would be, to have a parallel implementation that is using the RecyclerView instead of the ListView as independent library. As you seem to be very interested in this feature, maybe you will create such a fork :)

Best regards,
Ingo

Hi @ISchwarz23 i believe that if you are implementing ArrayAdapter you can actually recycle views with the view holder implementation on the adapter.

I think this is a very important feature since not recycling views is very critical on any mobile app. I recommend you to work on that if you have time, since this is a great approach and there are not many libraries on the web to implement easily a table view the way we use lists. Also i think Android should work on this... but what ever.

Hi @ciskeboekelo,

your idea about the view recycling was very nice. The result is a new generation of the SortableTableView which is based on the recyclerview. If you want to have a look on it visit sortabletableview.com.

With this new table it's also possible to have one data adpater per column. Which makes you code much cleaner and improves reusability. It also imports new features like selection and others.

Best regards,
Ingo
