Question

我正在实施Lottie动画，整个动画效果很好！但是，我想添加一些代码，这些代码将在30帧之后暂停动画，然后我可以在一定时间后恢复。这是迄今为止的代码

animationView.playAnimation(0, 30)
animationView.addAnimatorListener(object : Animator.AnimatorListener {
   override fun onAnimationEnd(animation: Animator) {
      if (isLoading == false) {
         //Everything has loaded. Continue Animation 

         //This line has no effect. The animation does not continue
         animationView.playAnimation(30, 60)
         //Resuming the animation just makes the animation disappear
         //animation.resume()
      }
 }

任何建议将不胜感激！

你可以做的是使用LottieAnimationView中的进度，主题和标记，这样你就可以暂停一定的进度和恢复确切地说，当您需要再次播放动画时

我创建了以下示例：

animationView.playAnimation()
animationView.loop(false)

isAnimating = true // Setup your flag

thread {
    while (isAnimating){ // Loop that checks the progress of your animation
        if (animationView.progress >= 0.5f){// If animation reaches 50%
            runOnUiThread {
                animationView.pauseAnimation()// Pause Animation
            }
            Thread.sleep(5000) // Pause for 5 seconds
            runOnUiThread {
                animationView.playAnimation(0.5f,1f) // Resume your animation from 50% to 100%
            }
            isAnimating = false
        }
        if(animationView.progress >= 1f){ // If animation reaches 100% stop animation
            runOnUiThread {
                animationView.cancelAnimation()
                isAnimating = false
            }
        }
    }
}

希望它有所帮助。
