如何使用 ListAdapter 更新回收站视图？

Question

I'm currently using RecyclerView ListAdapter.

I would like to know what is the equivalent of notifyDataSetChanged or how to update the whole list after adding a value/record?

I am using this method currently, but it's not updating if it's not refreshed.

Initializing the record

mList = new ArrayList<>();

mList.add(new ModelClass();

mAdapter.submitList(mList);

Some code after creating a new record

mAdapter.submitList(null)

mAdapter.submitList(modifiedList)

I'm thinking of going back to RecyclerView.Adapter<VH> and notifyDataSetChanged() so that my problems are solved. What do you think?

Answer 1

There are multiple ways to achieve same.

 adapter.notifyItemInserted(itemIndex);

Here, is the position in the array where you want to add a new element. This will not refresh the entire list on the recycler view.
But will just add this element to that position.

 arrayData.addAll(insertIndex, items); adapter.notifyItemRangeInserted(itemIndex, items.size());

 adapter.notifyDataSetChanged();

So, like I have mentioned above there are multiple way of updating a list in recycler view
