-// Animation calculates a value according to the current input time.
-//
-// 1. First we need to use setDuration(int) to set the duration of the
-//    animation. The duration is in milliseconds.
-// 2. Then we should call start(). The actual start time is the first value
-//    passed to calculate(long).
-// 3. Each time we want to get an animation value, we call
-//    calculate(long currentTimeMillis) to ask the Animation to calculate it.
-//    The parameter passed to calculate(long) should be nonnegative.
-// 4. Use get() to get that value.
-//
-// In step 3, onCalculate(float progress) is called so subclasses can calculate
-// the value according to progress (progress is a value in [0,1]).
-//
-// Before onCalculate(float) is called, There is an optional interpolator which
-// can change the progress value. The interpolator can be set by
-// setInterpolator(Interpolator). If the interpolator is used, the value passed
-// to onCalculate may be (for example, the overshoot effect).
-//
-// The isActive() method returns true after the animation start() is called and
-// before calculate is passed a value which reaches the duration of the
-// animation.
-//
-// The start() method can be called again to restart the Animation.
