不知道为什么。预览图片这个功能，在某些手机上（荣耀，魅族）打开关闭图片时屏幕都会抖一下，而在小米和客户端上时就不会抖，想问一下这是为什么？？有没有解决的方法

wtml

<view class='picture' bindtap='previewPicture2' data-index='{{index}}'>

<view >

<image class='picture_one' mode='aspectFill' wx:for="{{item.messagePicture}}" src="{{item}}" data-index='{{index}}' data-pic='{{item}}' bindtap='previewPicture'></image>

</view>

</view>

css

.picture{

margin-left: 176rpx;

width: auto;

height: auto;

}

.picture_one{

width: 160rpx;

height: 160rpx;

padding-right: 20rpx;

}

js

previewPicture2: function (e) {

console.log(e)

var that = this

var pic = that.data.pic

var index2=e.currentTarget.dataset.index

wx.previewImage({

current: pic, // 当前显示图片的http链接  

urls: that.data.demands[index2].messagePicture // 需要预览的图片http链接列表  

})

},

previewPicture: function (e) {

let that = this

console.log(e)

var pic = e.currentTarget.dataset.pic;

that.setData({

pic:pic

})

},
