Android实现扫描二维码动画效果

如图：

中心的线在从上到下的动画效果

代码实现：

 private fun initAnimation() {
        val mAnimation = TranslateAnimation(TranslateAnimation.ABSOLUTE, 0f, TranslateAnimation.ABSOLUTE,0f, TranslateAnimation.RELATIVE_TO_PARENT, 0f,
            TranslateAnimation.RELATIVE_TO_PARENT, 0.9f)
        mAnimation.duration = 1500
        mAnimation.repeatCount = -1
        mAnimation.repeatMode = Animation.RESTART
        mAnimation.interpolator = LinearInterpolator()
        binding.imgLine.animation = mAnimation

    }

完成
