From class java.lang.Object

From interface android.animation.TimeInterpolator

FastOutSlowInInterpolator ()

float getInterpolation (float input)

将代表动画流逝部分的值映射到表示插值部分的值。然后将该内插值乘以动画值的变化以导出当前流逝的动画时间的动画值。

参数(Parameters)
`input`	`float`: A value between 0 and 1.0 indicating our current point in the animation where 0 represents the start and 1.0 represents the end

返回(Returns)
`float`	The interpolation value. This value can be more than 1.0 for interpolators which overshoot their targets, or less than 0 for interpolators that undershoot their targets.
