How to prevent RecyclerView item from blinking after notifyItemChanged(pos)?

RecyclerView has built in animations which usually add a nice polished effect. in your case you’ll want to disable them:

((SimpleItemAnimator) mRecyclerView.getItemAnimator()).setSupportsChangeAnimations(false);

(The default recycler view animator should already be an instance of SimpleItemAnimator)

For Kotlin,

(mRecyclerView?.itemAnimator as SimpleItemAnimator).supportsChangeAnimations = false
