StackLayout

层叠View支持手势左右滑动，自动轮播，过渡动画

1.onMeasure通过StackAdapter适配器取到itemView加入到StackLayaout容器

onMeasure() through stackAdapter add view to StackLayout

2.onLayout取到childView按照层叠布局

onLayout() get child view layout stack ui

3.onInterceptTouchEvent处理手势支持子View及Velocity

onInterceptTouchEvent() support child view gesture

4.onTouchEvent处理手势，释放后播放动画平滑过渡

onTouchEvent() swipe animation,when release recover animation

Use

implementation 'com.uis:stacklayout:0.5.0'
Name Descript Value
stackSpace 间距(space) 默认值(default)：10dp
stackEdge 边界距离(edge) 默认值(default)：10dp
stackZoomX x方向缩放(x zoom) 0<x<=1,1表示等间距，默认值(default)：1
stackPadX x方向偏移(x padding) 表示偏移间距,默认值：0
stackPadX PadX*(Size-1) < Space PadX优先级高于ZoomX
stackZoomY y方向缩放(y zoom) 0<y<=1,1表示和顶层等高度，默认值：0.9
stackLooper 自动轮播(looper) false/true
stackSize 层叠数量(stack size) 3
stackEdgeModel 层叠位置(stack model) left/right
