android-pile-layout

介绍：

横向滚动的卡片堆叠布局

运行效果：

使用说明：

1. 在xml文件中定义 PileLayout 

<com.stone.pile.libs.PileLayout
        android:id="@+id/pileLayout"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:paddingBottom="5dp"
        android:paddingTop="5dp"
        pile:displayCount="1.5"
        pile:interval="10dp"
        pile:scaleStep="0.22"
        pile:widthHeightRate="1.22" />

可以用这四个参数自定义pileLayout：

name	format	description
interval	dimension	items-margin each other
sizeRatio	float	each item's height/witdth
scaleStep	float	size scale step when needed
displayCount	float	number of items that may display

2.  Java 文件中:

pileLayout = (PileLayout) findViewById(R.id.pileLayout);
pileLayout.setAdapter(new PileLayout.Adapter() {
            @Override
            public int getLayoutId() {
                // item's layout resource id
                return R.layout.item_layout;
            }
            @Override
            public void bindView(View view, int position) {
                ViewHolder viewHolder = (ViewHolder) view.getTag();
                if (viewHolder == null) {
                    viewHolder = new ViewHolder();
                    viewHolder.imageView = (ImageView) view.findViewById(R.id.imageView);
                    view.setTag(viewHolder);
                }
                // recycled view bind new position
            }
            @Override
            public int getItemCount() {
                // item count
                return dataList.size();
            }
            @Override
            public void displaying(int position) {
                // right displaying the left biggest itemView's position 
            }
            @Override
            public void onItemClick(View view, int position) {
                // on item click
            }
});
