enable users to slide card to the left or right smoothly and continuously

“无耻一点

如果我能不要脸一些，我会说这个项目有以下优点：

快。真的流畅，滑动的手速再快也赶不上代码刷新view的速度快。 高效。仅仅四个卡片view轻松搞定任意多的数据。 灵活。自定义ViewGroup对卡片view的高度实现了自适应。 细节。卡片之间联动的视觉效果，是像素级的精确。 不信，你下载下来look看看。”

最后这句话“不信，你下载下来look看看。”是个病句哇，如果翻译的话：不信，你下载下来看看看看。。。这个很显然不符合本项目的文风呐。。所以是不是可以考虑改成“不信，你下载下来look look”。。。

Hi I'm using your library.I have one question.Is it a possible to add dinamically CardItemView view in CardSlidePanel.In this example you use static array,but i have json and different size array. I tried to remove some elements in you arrayList ,but i have IndexOf exceplion

I tried like this but my new view is null-

` slidePanel.setAdapter(new CardAdapter() { @Override public int getLayoutId(int index) { if (dataList.get(index).imagePath == null) { return R.layout.gads; } else { return R.layout.card_item; }

        }

        @Override
        public int getCount() {
            return dataList.size();
        }

        @Override
        public void bindView(View view, int index) {
            if (dataList.get(index).imagePath == null) {
                AdViewHolder adViewHolder;
                adViewHolder = new AdViewHolder(view);
                AdRequest request = new AdRequest.Builder().build();
                if (adViewHolder.adView != null) {
                    adViewHolder.adView.loadAd(request);
                    adViewHolder.adView.setAdListener(new AdListener() {
                        @Override
                        public void onAdFailedToLoad(int i) {
                            super.onAdFailedToLoad(i);
                        }

                        @Override
                        public void onAdLeftApplication() {
                            super.onAdLeftApplication();
                        }

                        @Override
                        public void onAdLoaded() {
                            super.onAdLoaded();
                        }
                    });
                }

            } else {
                Object tag = view.getTag();
                ViewHolder viewHolder;
                if (null != tag) {
                    viewHolder = (ViewHolder) tag;
                } else {
                viewHolder = new ViewHolder(view);
                    view.setTag(viewHolder);
                }

                viewHolder.bindData(dataList.get(index));
            }

        }

        @Override
        public Object getItem(int index) {
            return dataList.get(index);
        }

        @Override
        public Rect obtainDraggableArea(View view) {
            // 可滑动区域定制，该函数只会调用一次
            View contentView = view.findViewById(R.id.card_item_content);
            View topLayout = view.findViewById(R.id.card_top_layout);
            View bottomLayout = view.findViewById(R.id.card_bottom_layout);
            int left = view.getLeft() + contentView.getPaddingLeft() + topLayout.getPaddingLeft();
            int right = view.getRight() - contentView.getPaddingRight() - topLayout.getPaddingRight();
            int top = view.getTop() + contentView.getPaddingTop() + topLayout.getPaddingTop();
            int bottom = view.getBottom() - contentView.getPaddingBottom() - bottomLayout.getPaddingBottom();
            return new Rect(left, top, right, bottom);
        }
    });`

childWith + changedView.getLeft() --> 不是很清楚具体的含义.

//这里是向左消失的计算. finalY = yvel * (childWith + changedView.getLeft()) / (-xvel) + changedView.getTop()

我这里换成了这样. 因为 X,Y 消失消耗时间一致. yvel / xvel = dy / dx finalY = changedView.getTop() + dx * yvel / xvel; 也就是. finalY = yvel * changedView.getRight() / (-xvel) + changedView.getTop();

测试后发现这种算法也能完美运行.但是finalY是不一样的..这就疑惑了..到底哪个才比较合适?

I'm trying to show 4 cards at a time by changing VIEW_COUNT = 5. VIEW_COUNT is inside the class CardSlidePanel. But nothing is changing but if i'm assigning it as 3 or 2, it works well. Any help will be appreciated.

https://github.com/xmuSistone/CardSlidePanel/blob/70dab2540745c39bfef805c4621b52ebfb85fc97/CardSlidePanel/library/src/main/java/com/stone/card/library/CardSlidePanel.java#L226-L234 这里要改成index + 2 >= viewList.size()，否则调用processLinkageView(changedView);的时候ajustLinkageViewItem(changedView, rate2, 2); 会数组越界

每次划完了，重新给集合里添加数据，就会数组越界

java.lang.IndexOutOfBoundsException: Index: 4, Size: 4 at java.util.ArrayList.get(ArrayList.java:411) at com.SimpleDate.FaMy.ui.view.tantan.CardSlidePanel.onLayout(CardSlidePanel.java:499) at android.view.View.layout(View.java:18878) at android.view.ViewGroup.layout(ViewGroup.java:5953) at android.support.design.widget.HeaderScrollingViewBehavior.layoutChild(HeaderScrollingViewBehavior.java:132) at android.support.design.widget.ViewOffsetBehavior.onLayoutChild(ViewOffsetBehavior.java:42) at android.support.design.widget.AppBarLayout$ScrollingViewBehavior.onLayoutChild(AppBarLayout.java:1361) at android.support.design.widget.CoordinatorLayout.onLayout(CoordinatorLayout.java:894) at android.view.View.layout(View.java:18878)

Why are some cards semi-transparent? That is, their back cards are revealed http://www.upsara.com/images/ysbg_screenshot_1508184174.png http://www.upsara.com/images/vvbr_cap2ture.png http://www.upsara.com/images/lukm_screenshot_1508184195.png

This problem does not exist in the demo file. But with the implementation of your project, there is such a problem without any changes!
