RecyclerView blinking after notifyDatasetChanged()

Question

I have a RecyclerView which loads some data from API, includes an image url and some data, and I use networkImageView to lazy load image.

@Override
public vo         


        

Answer 1

Assuming mItems is the collection that backs your Adapter, why are you removing everything and re-adding? You are basically telling it that everything has changed, so RecyclerView rebinds all views than I assume the Image library does not handle it properly where it still resets the View even though it is the same image url. Maybe they had some baked in solution for AdapterView so that it works fine in GridView.

Instead of calling notifyDataSetChanged which will cause re-binding all views, call granular notify events (notify added/removed/moved/updated) so that RecyclerView will rebind only necessary views and nothing will flicker.
