Easing functions allow you to apply custom mathematical formulas to your animations. For example, you may want an object to realistically bounce or behave as though it were on a spring. You could use Key-Frame or even From/To/By animations to approximate these effects but it would take a ...

Android动画曲线库AndroidEasingFunctions AndroidEasingFunction是基于Easing Function(缓动函数)的Android动画曲线库。它提供了九大类27种动画曲线效果,可以使对应的属性按照时间进行变化。在动画实现时,它使用了开源动画库NineOldAndroid,所以可以支持Android 3.0等早期版本。
Easing function 用以描述参数值随时间而改变的变化率。 现实生活中的物体几乎不会以维持常数的速度移动,也不会瞬间开始和停止。当我们打开一个抽屉时,一开始的速度非常快,在拉出来之后慢下来。将物品跌落地板时,它一开始会向下加速,然后在击中地板后回弹。
In order to use Robert's easing functions, we need to setup our animation in a certain way where his easing functions can be used "out of the box" without any modification required. This isn't as intrusive as it sounds, so let's look at what these changes involve at a very high lev...
Easing functions describe functions that control the way an interpolation between 0 and 1 is done. The most basic easing function, linear, is just a linear interpolation at constant speed. Other more advanced easing functions can have acceleration at the beginning, the end or both or deceleratio...
