如题，在swiper下scroll-view加了 scroll-x="true"  scroll-y="true" enable-back-to-top="true" style="height: 100%;"还是没有用，无法横向滚动也无法纵向滚动

部分代码如下：

wxml:

     <swiper-item class="item-list"  >  
       <view class="list-view">
              <view class="classname">
                <scroll-view class="scro" scroll-x="true" scroll-y="true"
                enable-back-to-top="true" style="height: 100%;"
                overflow="auto">

wxss:

    .item-list{
  height: 100%;
  /*border: 5px solid red;*/
  text-align: left;
}

.scro{
    height: 100%;
    min-width: 100px;
}
