先吐槽一下，微信官方虽然支持了Animation，但是对动画的控制却做的不够到位，比如动画开始和结束的监听，一直存在不生效的bug，久久未能解决。还有动画的过程也不能控制暂停和继续。以下是我自己的解决方案，主要就是用了两个动画，一个是动的，一个是暂停的，暂停和继续是通过两个动画切换进行的。效果如下

效果图：

扫码动画暂停的时候，将扫描线设置在了中间位置，可以在代码中自行调整

wxml代码：

<view>
  <view class="scan-container">
    <view class="scan-box" />
    <view class='scan-animation' animation="{{scanAnimation}}" />
  </view>
  <view class="footer-container">
    <view class="input-button" bindtap="startScan">开始扫描</view>
    <view class="input-button" bindtap="pauseScan">暂停扫描</view>
  </view>
</view>

js代码：

Page({

  data: {
    //扫描线动画
    scanAnimation: null,
    //重复扫描的定时器
    scanInterval: null,
    //是否正在扫描中
    isScanning: false
  },

  /**
   * Lifecycle function--Called when page load
   */
  onLoad() {

  },

  /**
   * Lifecycle function--Called when page show
   */
  onShow() {

  },

  /**
   * 开始动画的时候，首先创建一个立马执行的扫描动画，再创建一个循环执行扫描动画的定时器
   * 
   * 定时器设置比一套完整扫码动画时间稍大，是为了应对初始化的时候，动画执行稍慢的情况
   */
  startScan() {
    if (this.data.isScanning) {
      return false
    } else {
      this.createScanAnimatiion()
      this.data.scanInterval = setInterval(() => {
        this.createScanAnimatiion()
      }, 6100)
    }
  },

  /**

  createScanAnimatiion() {
    var animation = wx.createAnimation({});
    animation.translateY(220).step({
      duration: 3000
    }).translateY(0).step({
      duration: 3000
    });
    this.setData({
      scanAnimation: animation.export(),
      isScanning: true
    })
  },

  /**

  createPauseAnimation() {
    var pauseAnimation = wx.createAnimation({});
    pauseAnimation.translateY(100).step({

    this.setData({

    }

  onHide() {

      clearInterval(this.data.scanInterval);
