    用Kotlin实现抖音爆红的文字时钟,征服产品小姐姐就靠它了(上)

    该方法接收一个degrees: Float参数,是控制「时圈」整体的旋转的,后文就是不断改变该值,而产生动画效果的。 并且因为三个圈的动画方向都是逆时针,所以这个degrees是个始终会是个负数。 「时圈」 val iDeg = 360 12f * i canvas.rotate(iDeg) 这里处理当前时间点的透明度,因为degrees控制整体逆时针旋转 iDeg控制绘制时顺时针,所以两者和为 * 0.16f 处理整体旋转 canvas.save() canvas.rotate(degrees) for (i in 0 until 60) { canvas.save() val iDeg = 我们再看一下onDraw()中的代码,绘制三个圈的方法都会接收一个相应的degrees: Float参数,这个是控制一个圈的整体旋转的,而且要逆时针转,所以始终得是负数。 让时钟转的优雅点基于我们已经知道了,时钟动起来的本质就是在一段时间内(比如150ms)不断的改变参数degrees: Float的值并触发重绘方法,这样就产生了人眼看到的动画效果。
