            ViewModel still displaying old data after dialog dismissed and parent fragment back to view
            Asked 2020-Sep-13 at 06:13

            I'm still trying to wrap my head around working with viewmodels and a bit confused now that I also have a dialog and recyclerview items but will try to be as clear as I can here if I can get any help please.

            I have a dialog with items that when one of them is selected and closed should return data to my calling fragment so the selected item is displayed under that view.

            However, once the item is selected and the dialog dismissed, I don't see the new selected item as the one showing on the UI but still the old item instead. (When the fragment is first started it displays the item that is set as selected on my list. The selected value is hardcoded at first but updated when the item is clicked and I can see the update has taken place when I debug the viewmodel observer inside the onDismiss method for the dialog).

            I'm a couple of hours on this and have tried a few different things such as calling the viewmodel inside onResume or onDismiss and changing the viewmodel to be initiated by by activityViewModels() as per this post but none of these have worked so far and I think I'm stuck at the moment. Below my most recent version of the code.

            Asked 2020-Aug-03 at 02:56

            I see this question asked a few times but maybe because I'm using the Groupie library for adding items to my adapter, I'm not being able to unselect the other items when one of the them is selected (similar to radio button functionality). I'm trying to notify the adapter of changes and somewhat get the position of the item selected but I think I may still be missing something if someone could point this out for me please.

            First option: Create your adapter and create a local variable in the adapter and check the position selected it is the variable.

            Second option: Create the variable in the Activity called selected_position. When the function onClickItem called update this variable and notify adapter change. in your item check the variable in the activity, example:

            How to notify and update list when item has been deleted using Groupie RecyclerView library and Kotlin
            Asked 2020-Aug-01 at 17:19

            I have a RecyclerView implemented with the Groupie library and I can delete an item from the list fine, however need to update the view to see the change. I'd like to have something like notifyDataSetChanged() instead, so the list updates immediately. I'm a bit confused at this stage though, tried a few different ways to get an interface from the class that hosts my view holder to be triggered from the fragment that holds the adapter but I think I'm stuck now if I could get some help please.

            I think you are missing this concept from the groupie Readme:

            Modifying the contents of the GroupAdapter in any way automatically sends change notifications. Adding an item calls notifyItemAdded(); adding a group calls notifyItemRangeAdded(), etc.

            So to remove an item, call section.remove(item). However, in your onClickItem function you currently only pass the position. Pass the item like clickListener?.onClickItem(this@RecyclerProductItem) instead. Even more ideally and safely you should remove by product.id, e.g. clickListener?.onClickItem(this@RecyclerProductItem.product.id) then in onClickItem() you just search for the item with that product id and remove it. Let me know if I'm not clear.

            Groupie abstracts away the complexity of multiple item view types. Each Item declares a view layout id, and gets a callback to bind the inflated layout. That's all you need; you can add your new item directly to a GroupAdapter and call it a day.

            Item with Kotlin The Item class gives you simple callbacks to bind your model object to the generated fields. Because of Kotlin Android extensions, there's no need to write a view holder.**
