纯 nvue项目（uniapp模式）。编辑器版本 2.4.0.20191112-alpha
uni.getSystemInfo 获取屏幕的高有获取错的情况。我把获取屏幕高放到组件就出现了。多次测试多个设计都出现
我上传了完整demo代码，请管理员下载执行看看。console.log 会把数据打印出来， at components/myList/myList.js:36
【ios正常】【安卓不行】
多运行，或者打开几次会得到不一样的结果

会不会你们的安卓手机性能都太好。我用mumu（模拟器）和小米8手机（真机）都可以复现

回复 DCloud_uniCloud_WYQ: 果然时机问题。这样算bug吗？越差性能到安卓手机时机就越晚。延迟多少毫秒合适不好把我。
怀念mui时代到 ready事件。个人认为video组件和其他比较重到组件都需要ready时间感觉。
比如video差的时机还没ready好就直接触发播放事件就会死机白屏等【曾尝试自己封装安卓的video播放器组件就可以避免差的安卓手机做视频播放功能崩溃】。目前我的仿抖音的app性能使用起来非常好，就是差一点的安卓手机会开机的时候死机白屏等问题出现。
