获取 Animated.Value 的当前值，React-native [英] Get current value of Animated.Value, React-native

问题描述

我正在尝试使用插值为 View 设置动画.我想获得我的 Animated.Value 的当前值，但不知道如何.我不明白如何使用 React 原生文档.

I'm trying to animate View with interpolate. I'd like to get a current value of my Animated.Value, but don't know how. I didn't understand how to do it with React-native docs.

this.state = {
      translateAnim: new Animated.Value(0)
}
DeviceEventEmitter.addListener('Accelerometer', function (data) {
  console.log(this.state.translateAnim);
  // returns an object, but I need a value in current moment
}
