堆叠滑动控件,类似于社交软件探探的效果,并增加以下扩展:

  • 支持滑动方向控制
  • 支持消失方向控制
  • 支持嵌入到 ViewPager 等滑动控件
  • 支持内嵌 ListView,RecycleView 等滑动控件

效果演示

演示 1-快速滑动飞出     演示 2-代码控制飞出

演示 3-嵌入到 ViewPager     演示 4-内嵌 RecycleView


如何使用

  • xml 引入 StackCardsView:
    <com.beyondsw.lib.widget.StackCardsView
        android:id="@+id/cards"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        app:itemHeight="340dp"
        app:itemWidth="340dp"
        android:paddingBottom="66dp"
        android:clipToPadding="false"
        />

支持的 xml 属性设置:

属性名 说明 类型 是否必须
itemWidth 卡片宽度 dimension
itemHeight 卡片高度 dimension
maxVisibleCnt 不滑动时最多可以看到的卡片数 integer
edgeHeight 层叠效果高度 dimension
scaleFactor 每层相对于上层的 scale 系数 float
alphaFactor 每层相对于上层的 alpha 系数 float
dismissFactor 滑动距离超过控件宽度的多少比例时消失 float
dragSensitivity 滑动灵敏度 float



设置 adapter:

  mCardsView = Utils.findViewById(root,R.id.cards);
  mCardsView.addOnCardSwipedListener(this);
  mAdapter = new CardAdapter();
  mCardsView.setAdapter(mAdapter);


public class CardAdapter extends StackCardsView.Adapter {

    private List<BaseCardItem> mItems;

    public void appendItems(List<BaseCardItem> items){
        int size = items == null ? 0 : items.size();
        if (size == 0) {
            return;
        }
        if (mItems == null) {
            mItems = new ArrayList<>(size);
        }
        mItems.addAll(items);
        notifyDataSetChanged();
    }

    public void remove(int position){
        mItems.remove(position);
        notifyItemRemoved(position);
    }

    @Override
    public int getCount() {
        return mItems == null ? 0 : mItems.size();
    }

    @Override
    public View getView(int position, View convertView, ViewGroup parent) {
        return mItems.get(position).getView(convertView,parent);
    }

    @Override
    public int getSwipeDirection(int position) {
        //这里控制每张卡的支持滑动超过一定距离消失的方向
        BaseCardItem item = mItems.get(position);
        return item.swipeDir;
    }

    @Override
    public int getDismissDirection(int position) {
        //这里控制每张卡的支持滑动超过一定距离消失的方向
        BaseCardItem item = mItems.get(position);
        return item.dismissDir;
    }

    @Override
    public boolean isFastDismissAllowed(int position) {
        //这里控制每张卡的支持快速滑动消失的方向
        BaseCardItem item = mItems.get(position);
        return item.fastDismissAllowed;
    }

    @Override
    public int getMaxRotation(int position) {
         //这里控制每张卡的最大旋转角
        BaseCardItem item = mItems.get(position);
        return item.maxRotation;
    }
}
