让一个图片匀速转圈的动画在安卓上边正转完后倒转，不知道有没有人遇到过 animations:function(){ var animation = wx.createAnimation({ duration: 2000, timingFunction: 'linear', }) this.animation = animation this.setData({ animationData: animation.export() }) var n = 0; setInterval(function () { n = n + 1; console.log(n); this.animation.rotate(360 * (n)).step() this.setData({ animationData: this.animation.export() }) }.bind(this), 2000) },
