基本上,我正在使用带有gridAdapter的RecyclerView从服务器加载图像。但问题是RecyclerView的项目以一种奇怪的方式闪烁。我尝试了所有可能的解决方案,但到目前为止都没有起作用。
我尝试将glide版本从4.4.0更新到4.8.0,但是徒劳无功。我还尝试禁用RecyclerView的动画,但那也没什么用。请问有人可以帮我解决这个问题吗?

代码:
GridLayoutManager gridLayoutManager = new GridLayoutManager(v.getContext(),3);
gridLayoutManager.setSmoothScrollbarEnabled(true);
gridLayoutManager.setItemPrefetchEnabled(true);
gridLayoutManager.setInitialPrefetchItemCount(20);
posts_rView.setLayoutManager(gridLayoutManager);
posts_rView.setItemAnimator(null);
posts_rView.setHasFixedSize(true);
gridPostAdapter=new StarredAdapter(timelineDataList);
posts_rView.setAdapter(gridPostAdapter);

JSONArray jsonArray=(JSONArray)args[0];
Needle.onMainThread().execute(() -> {
timelineDataList.clear();
swipeRefreshLayout.setRefreshing(false);
