recyclerView滞后滚动

Question

I have a recyclerView with match parent items. In recyclerView item, I have 48 relative layouts and a background and it scrolls without any problems. Since I added lottie animationView in items, recyclerView scrolls but with lag. I tried to change the cache size, pause animation when it detached from window, compress background image, using another thread, converting images to bitmap but it did not help.

Should i try to draw views or something like it or is there something else that i can do?

Answer 1

after one week of searching and testing another ways to play animation i found my solution solution is to use different method to play animation like gif but gif has transparenty and if you have an animation that it has transparent parts, the animation have white border that is very awfull to use, another way to do this is to use apng ,apng is a animated version of png and it resolve the problem of transparenty,but in recyclerView it has problems, like when you scroll recyclerView up or down that animation get out of screen, it will stop and you should set up animation when ever it attached to windows and it decrease the performance, but what is the final solution of this problem? webp. webp is a format that created by google and you can use it in android with fresco library, and use webp animated images that has not problem of transparenty and it is very high performance, acctually animation size is lower than a lottie animation! and is very easy to use, i added the library,and easily call it :

 DraweeController controller = Fresco.newDraweeControllerBuilder()
            .setUri(yourUri)
            .setAutoPlayAnimations(true)
            .build();

and easily set controller to SimpleDraweeView :

simpleDraweeView.setController(controller);

it was my solution to my own question, hope it help you.

Try putting the recyclerview in side a NestedScroll View. and in recyclerView put nestedscrollingEnabled = false.
