View scaling improperly

When we attach it a card with different height then its causing view scaling issue. View are cropped.

Problems during scrolling with recyling views

As you can see from the screenshots, whenever I scroll my list down and then i go up again, there are some rendering problems.

Are these known problems?

child view visibility

changing visibility of specific View (view inside viewItem ) at some position than view height does not change. its height stays same.

Different behaviour On Kitkat and above Kikat

I have tested VegaLayoutManager in Kitkat and above . There is a behavior difference .

On kitkat - On scroll to bottom, the last items scrolls to the top .
Above Kitkat - The last item remains on the bottom of recycler view .

Is this the issue with RecyclerView in Kitkat or some other ?

出现You must override smoothScrollToPosition to support smooth scrolling

I want to use the same animation as the library have but I just need to remove code which is for auto scroll when the first position hide. I need behavior same like the normal recycled view. can you please guild me how can I stop auto-scroll when move position?

Thanks

分页加载数据item空白

You must override onLayoutChildren(Recycler recycler, State state)

After scrolling and keep screen visible without touching after 2-3 min it hides recycler view items. and error is

E/RecyclerView: You must override onLayoutChildren(Recycler recycler, State state)

when u touch again it shows recyclerview items API23 device i m using.

If you want to check in android application this is link -

pls check (select currency)

Recycler items gets invisible when scrolling often (API 21)

To solve the problem of viewpager: an instance of onflinglistener already set.解决ViewPager闪退问题。

VegaLayoutManager: line:284
@OverRide
public void onAttachedToWindow(RecyclerView view) {
super.onAttachedToWindow(view);
StartSnapHelper snapHelper = new StartSnapHelper();
view.setOnFlingListener(null);
snapHelper.attachToRecyclerView(view);
}

(Illegal state Exception) Crash Issue Solved

    recyclerView.setOnFlingListener(null);

Problems with space between items.

Hello, thanks for this spectacular library.

I have a problem with my RecyclerView: the linear layout manager works fine but as soon as I try yours, I have this problem (Photos: https://photos.app.goo.gl/KB84ASKxTwdrZkVH2 )

Is there a way to fix it?

As you can see, there is A LOT of space between some items and the last doesn't have the little textview in the bottom of the card.

Thanks

detachAndScrapAttachedViews()

想請教一下
detachAndScrapAttachedViews(recycler), 究竟是只有把第一個View放進緩存, 還是把所有的View 都放進緩存?

How can I modify the layout manager to achieve a horizontal scrolling effect?

Thanks for the amazing library. I was wondering if we could achieve this effect for a horizontally scrolling recycler view like it's shown in the attachment.

当recyclerView中item没超过屏幕时候滑动会闪屏

应该在computeMaxScroll()方法中，当得到最低部item.bottom-getHeight()的值maxScroll是否小于0，如果小于0就直接return掉，这样子就不允许滑动了。望采纳

setStackFromEnd

how can i set StackFromEnd?

送给有需要的人

本来想看源码学习的，看着好多代码，累了，就想着自己弄，
看了看效果，感觉就是线性的，唯一的区别就是第一个item有个变化而已。
代码如下，继承LinearLayoutManager重写如下的方法即可，基本可以达到效果，好像有人想要横向的，逻辑也差不多。

` var oldChild0:View?=null;
override fun scrollVerticallyBy(dy: Int, recycler: RecyclerView.Recycler, state: RecyclerView.State?): Int {
val result=super.scrollVerticallyBy(dy, recycler, state)
if(childCount>1){
val child1=getChildAt(1)
val child0=getChildAt(0)
if(oldChild0!=null&&oldChild0!=child0){
resetChild(oldChild0!!)
}
oldChild0=child0
var scale=0.7f+0.3f*(child1.top)/getDecoratedMeasuredHeight(child1)

        child0.pivotX=child0.width/2f
        child0.pivotY=child0.height/1f
        child0.scaleX=scale
        child0.scaleY=scale
        child0.translationY=getDecoratedMeasuredHeight(child1)-child1.top.toFloat()
        child0.alpha=scale
        if(scale<0.7){
            resetChild(child0)
            removeAndRecycleView(child0,recycler)
        }
    }
    return  result
}
private fun resetChild(child:View){
    child.apply {
        pivotY=this.width/2f
        pivotX=this.height/1f
        scaleX=1f;
        scaleY=1f;
        alpha=1f;
        translationY=0f
    }
}

很强大的库，感谢分享，能不能扩展下呢

比如可以跟LinearLayoutMangear一样往上滑，但是当前显示的第一个item跟现在一样缩小

Not able to search for recyclerView items

Hi, assume that you have a RecyclerView containing 100 items inside it.
Each list item has TextViews and you want to make a search with a help of EditText.

When the list has first loaded with containing 100 items and you made a search, you don't see any problem and you can make a achieved search.

But when you scroll the list to the bottom and make for a item which is collapsed by another item(am in it is the main feature VegaLayoutManager) search doesn't show list items. (Search process is succeed but view's does not appear.

I appreciate for any useful information. Thanks for great job !

demo显示无内容

把demo下载来运行，结果什么都不展示。把recyclerView.setLayoutManager(new VegaLayoutManager());换成recyclerView.setLayoutManager(new LinearLayoutManager(this));有内容，但是没有了效果
