notifyItemChanged(pos)后如何防止RecyclerView项目闪烁? [英] How to prevent RecyclerView item from blinking after notifyItemChanged(pos)?

问题描述

我目前有一个回收站视图，其数据每5秒更新一次.要更新列表中的数据，我正在使用

I currently have a recycler view whose data updates every 5 secs. To update the data on the list, I am using

notifyItemChanged(position);
notifyItemRangeChanged(position, mList.size());

每次调用notifyItemChanged()时，回收台视图上的项目都会正确更新，但是它将闪烁，因为这将导致再次调用onBindViewHolder.因此，好像每次都是新的负载.如果可能的话，如何防止这种情况发生?

Each time I call notifyItemChanged(), the items on my recycler view update properly, however, it will blink because this causes onBindViewHolder to be called again. So it's as though it is a fresh load each time. How can I prevent this from happening, if possible?

推荐答案

RecyclerView具有内置的动画，这些动画通常会添加精美的效果.在您的情况下，您将要禁用它们:

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);

(默认的回收者视图动画师应该已经是 SimpleItemAnimator )

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