I also tried scrollToPositionWithOffset, and it's make that I need, but now, without smooth effect.

But, I need to set scrolled position on top of screen(if is possible).

I'm ovverride method smoothScrollToPosition in LinearLayoutManager, and it's work fine. Show your love by sharing this blog with your fellow developers.I'm tring to make smooth scroller to need position in recyclerView. These are things that we can do to improve the performance of RecyclerView. Generally, we do not change the size of the View Cache, but experiment with it, if it works for you, implement it. It means that when we scroll the RecyclerView such that there's a view that is just barely completely off-screen, the RecyclerView will keep it around so that we can scroll it back into view without having to call the onBindViewHolder() again. The offscreen view cache stays aware of changes in the attached adapter, allowing a LayoutManager to reuse those views unmodified without needing to return to the adapter to rebind them. setItemViewCacheSize (cacheSize )Īs per the official documentation: It sets the number of offscreen views to retain before adding them to the potentially shared recycled view pool. Whenever we have the use-case of the removal, the updation, the addition of item, use the Notify Item API. We can see the improvement in our RecyclerView by doing so. We should check our onBindViewHolder method and optimize it. Now remember that our goal is to simply pass a method to our ViewHoder object so that it gets called on every click. toast.show () must be called in order for the toast to be shown. Our onBindViewHolder method should do very less work. Toast.makeText () is used to create a Toast, it takes 3 parameters: the context, the text to be shown and the duration that the toast will be viewed. Problem Solved! Do less in onBindViewHolder method Then, we will be able to set the width and height prior only. When my activity launches, it should launch with a specific item snapped to center. SnapHelper helper new LinearSnapHelper () helper.attachToRecyclerView (recyclerView) Now, I have two scenarios where I would want an item to come to center. So, we should ask our backend developer to send the image size or the aspect ratio, accordingly, we can calculate the required width and height of the ImageView. For the adapter items to snap at the center, I've attached a LinearSnapHelper to the recyclerview. If we do not set the correct image width and height prior, the UI will flicker during the transition of loading(downloading of image) and setting of the image into the ImageView(actually making it visible when downloading completes). If our image width and height are dynamic(not fixed), and we are getting the imageUrl from the server.

By using the bitmap pool concept, we can avoid it. Let's get started Use Image-Loading LibraryĪs the Garbage Collection(GC) runs on the main thread, one of the reasons for unresponsive UI is the continuous allocation and deallocation of memory, which leads to the very frequent GC run. Let's see what are the things which we can do to improve the performance of the RecyclerView and hence, we get the smooth scrolling. is smoothScrollToPosition() which take position of recyclerview to scroll that. It leads to bad user experience as it seems that our Android App is laggy. Sometimes in our android apps need a marquee text effect like smooth.
