我要评论一、效果展示
二、源码分享

function adderror(numberstr,notestr,solutionstr){
var data = {number: numberstr,note:notestr,solution:solutionstr};
listmodel.append(data)
}
}
三、使用方法
dynamiccarousel{
anchors.fill: parent
anchors.margins: 5
anchors.horizontalcenter: parent.horizontalcenter
}
四、实现原理
通过pathview实现，通过路径和缩放来实现动态效果。
