Chapter 13.2, Problem 13.21CP

Explanation of Solution

setInterpolator method:

• The “setInterpolator” method allows stating the beginning and ending of animation.
• The format of method is

“transitionObject.setInterpolator(interpolatorValue)”.

• The “transitionObject” denotes a transition object and “interpolatorValue” denotes modifying value for interpolator.
• The constants used in “interpolatorValue” includes:
  • Interpolator.EASE_BOTH:
    • It causes an animation to ease in and out.
    • In this case animation starts slowly, increase speed and then slows down at end.
  • Interpolator.EASE_IN:
    • It allows an animation to start slowly but makes it stop quickly.
  • Interpolator.EASE_OUT:
    • It allows an animation to start quickly but makes it stop slowly.
  • Interpolator.EASE_DISCRETE:
    • It allows an animation to jump immediately from beginning to its end.
  • Interpolator...
