:neckbeard:customized layoutmanager,let item pile up like stackview/类似最美有物卡片堆叠效果

中文 （因为目前代码组织得非常烂，仅仅是个玩具，如果有Item 增删操作的话最好不要用进项目，因为predictive动画并不支持。当初只是模仿着写，对RV的一整套东西并没有理解很透彻）

Why

A long long time ago ,i was inspired by this project android-pile-layout ,the author cannot find the appropriate math model with LayoutManager .Now i have some spare time and try to do the UI with layoutManager,barely ok with the result.

Blog

this is the relevant blog ,i hope it helps to understanding it

Display

horizontal

vertical(only top)

Demo Apk

download(vertical support)

Attention

If you don't care about item ADD REMOVE operation, this is what you want, because predictive animation is not supported yet,otherwise take care!

Usage

Config config = new Config();
config.secondaryScale = 0.8f;
config.scaleRatio = 0.5f;
config.maxStackCount = 3;
config.initialStackCount = 2;
config.space = 70;
config.parallex = 1.5f;//parallex factor
config.align= Align.RIGHT
recyclerview.setLayoutManager(new StackLayoutManager(config));
recyclerview.setAdapter(new StackAdapter(datas));

stacklayoutmanager's Issues

Shared element transition with horizontal stack layout manager is glitchy

When i apply shared element transition to cards on back pressed there is some glitchy animation with the cards i've been trying to figure out the problem but i dont know why it is happening so if you could help me out a bit

怎么获取手势滑动的位置呢？

第一个item，点击事件界面不刷新

在position 为0 的时候 onBindViewHolder里面的点击事件，比如说
holder.ivPlay.setOnClickListener {
ToastUtils.showShort("you click")
holder.tvProcess.text = "shishi"
}
holder.tvProcess.text = "shishi"
这句话不能立刻生效，需要点击多次才能生效

cards overlaping and stuck in the middle how do it stop this behaviour

How to get the current item position?

牛皮。 只有这个控件我才可以和JzvdStd 这个播放控件一起用。

感谢大佬 网上一堆不靠谱的。 只能放图片不能带视频播放

divide by zero error when there is no data

How can i avoid divide by zero error when there is no data from server..

Align.RIGHT 时，config.initialStackCount 没用

Hi~ 你好，我发现 Align.RIGHT 时，config.initialStackCount = ？ 这是变量并没有用，那么怎么修改开始图片的index呢？？

Cards with Match_Parent width and height

How can I change it to display full size image to fill the screen?

滑动到指定位置

没有提供滑动到指定位置的接口

Slugness while scrolling

Cards are overlapping and getting stuck over others while scrolling and release in the middle of the screen and sometimes in fast scroll.

config.align = Align.BOTTOM not working

config.align = Align.BOTTOM is not working for vertical layout. Please fix it.

• Thanks

Vertical support.

I'm very interested in StackLayoutManager but I want to use in vertical recyclerView.

Thank you for your support.

设置为底部的时候，不显示

当设置为：config.align = Align.BOTTOM的时候，整个列表都不显示了，设置为：config.align = Align.TOP的时候，显示正常

可以设置无限滚动吗

java.lang.IllegalStateException: The specified child already has a parent. You must call removeView() on the child's parent first.

Hi your layout manager is very good however i'm getting this error in
private int fill(RecyclerView.Recycler recycler, int dy, boolean apply) {
int delta = direction.layoutDirection * dy;
// multiply the parallex factor
if (apply)
delta = (int) (delta * parallex);
if (direction == LEFT)
return fillFromLeft(recycler, delta);
if (direction == RIGHT)

        return fillFromRight(recycler, delta);
    if (direction == TOP)
        return fillFromTop(recycler, delta);
    else return dy;
}
