您好，问一下，解决了吗？ 能否看一下相关代码。

为什么我拿每一条的高度加起来算的会高了，是底层rpx转px的误差造成的吗

你好，可以通过getSystemInfo获取视口高度并设定scroll-view的height即可。

我想要它满屏显示，高度怎么设置，用100%也不行

scroll-view的高度请设置成小于内部元素的高度，这样scroll-view才能在y轴方向滚动。

eg：<scroll-view class="scroll-company" scroll-y="true" style="height: 500px" scroll-into-view="{{toView}}">

有人没

官方技术小哥，给看看问题呗
