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

for my application, I had some data changing but I didn't want the entire view to blink.

I solved it by only fading the oldview down 0.5 alpha and starting the newview alpha at 0.5. This created a softer fading transition without making the view disappear completely.

Unfortunately because of private implementations, I couldn't subclass the DefaultItemAnimator in order to make this change so I had to clone the code and make the following changes

in animateChange:

ViewCompat.setAlpha(newHolder.itemView, 0);  //change 0 to 0.5f

in animateChangeImpl:

oldViewAnim.alpha(0).setListener(new VpaListenerAdapter() { //change 0 to 0.5f
