Updated: Dec 26, 2021

  1. In Android animation I have implemented animation on that animation I have set scales of animation scaleX,ScaleY, view animate

  2. set Duration how much time we can see the animation.

  • void OnAnimationStart

  • void OnAnimationEnd

  • void OnanimationCancel

  • void OnanimationRepeat

In this animation we have to see decreasing when Animation Going To end.

there is countdown is working for 30 sec.




Animation Code :



   private void playAnim(final View view, final  int value, final int viewNum)
    {
       view.animate().alpha(value).scaleX(value).scaleY(value).setDuration(500)
               .setStartDelay(100).setInterpolator(new DecelerateInterpolator())
               .setListener(new Animator.AnimatorListener() {
                   @Override
                   public void onAnimationStart(Animator animation) {

                   }

                   @RequiresApi(api = Build.VERSION_CODES.LOLLIPOP)
                   @Override
                   public void onAnimationEnd(Animator animation) {
                       if(value==0)
                       {
                           switch (viewNum)
                           {
                               case 0:
                                   ((TextView)view).setText(questionList.get(quesNum).getQuestion());
                                   break;
                               case 1:
                                   ((Button)view).setText(questionList.get(quesNum).getOptionA());
                               case 2:
                                   ((Button)view).setText(questionList.get(quesNum).getOptionB());
                               case 3:
                                   ((Button)view).setText(questionList.get(quesNum).getOptionC());
                               case 4:
                                   ((Button)view).setText(questionList.get(quesNum).getOptionD());

                           }
                           if(viewNum!=0)
                               ((Button)view).setBackgroundTintList(ColorStateList.valueOf(Color.parseColor("#FFFF00")));
                           playAnim(view,1,viewNum);

                       }

                   }

                   @Override
                   public void onAnimationCancel(Animator animation) {

                   }

                   @Override
                   public void onAnimationRepeat(Animator animation) {

                   }
               });
    }
}
