Usage

Animate multiple view from one method

ViewAnimator
       .animate(image)
            .translationY(-1000, 0)
            .alpha(0,1)
       .andAnimate(text)
            .dp().translationX(-20, 0)
            .decelerate()
            .duration(2000)
       .thenAnimate(image)
            .scale(1f, 0.5f, 1f)
            .accelerate()
            .duration(1000)
       .start();

Without ViewAnimator

AnimatorSet animatorSet = new AnimatorSet();
animatorSet.playTogether(
  ObjectAnimator.ofFloat(image,"translationY",-1000,0),
  ObjectAnimator.ofFloat(image,"alpha",0,1),
  ObjectAnimator.ofFloat(text,"translationX",-200,0)
);
animatorSet.setInterpolator(new DescelerateInterpolator());
animatorSet.setDuration(2000);
animatorSet.addListener(new AnimatorListenerAdapter(){
    @Override public void onAnimationEnd(Animator animation) {

      AnimatorSet animatorSet2 = new AnimatorSet();
      animatorSet2.playTogether(
          ObjectAnimator.ofFloat(image,"scaleX", 1f, 0.5f, 1f),
          ObjectAnimator.ofFloat(image,"scaleY", 1f, 0.5f, 1f)
      );
      animatorSet2.setInterpolator(new AccelerateInterpolator());
      animatorSet2.setDuration(1000);
      animatorSet2.start();

    }
});
animatorSet.start();

Add same animation on multiples view

ViewAnimator
       .animate(image,text)
       .scale(0,1)
       .start();

Add listeners

ViewAnimator
       .animate(image)
       .scale(0,1)
       .onStart(() -> {})
       .onStop(() -> {})
       .start();

Use DP values

ViewAnimator
       .animate(image)
       .dp().translationY(-200, 0)
       .start();

Animate Height / Width

ViewAnimator
       .animate(view)
       .waitForHeight() //wait until a ViewTreeObserver notification
       .dp().width(100,200)
       .dp().height(50,100)
       .start();

Color animations

ViewAnimator
       .animate(view)
       .textColor(Color.BLACK,Color.GREEN)
       .backgroundColor(Color.WHITE,Color.BLACK)
       .start();

Rotation animations

ViewAnimator
       .animate(view)
       .rotation(360)
       .start();

Custom animations

ViewAnimator
       .animate(text)
       .custom(new AnimationListener.Update<TextView>() {
            @Override public void update(TextView view, float value) {
                  view.setText(String.format("%.02f",value));
            }
        }, 0, 1)
       .start();

Cancel animations

ViewAnimator viewAnimator = ViewAnimator
       .animate(view)
       .rotation(360)
       .start();

viewAnimator.cancel();

Enhanced animations ( Thanks AndroidViewAnimators, NiftyDialogEffects )

Path animations ( Read http://blog.csdn.net/tianjian4592/article/details/47067161 )

    final int[] START_POINT = new int[]{ 300, 270 };
    final int[] BOTTOM_POINT = new int[]{ 300, 400 };
    final int[] LEFT_CONTROL_POINT = new int[]{ 450, 200 };
    final int[] RIGHT_CONTROL_POINT = new int[]{ 150, 200 };
    Path path = new Path();
    path.moveTo(START_POINT[0], START_POINT[1]);
    path.quadTo(RIGHT_CONTROL_POINT[0], RIGHT_CONTROL_POINT[1], BOTTOM_POINT[0], BOTTOM_POINT[1]);
    path.quadTo(LEFT_CONTROL_POINT[0], LEFT_CONTROL_POINT[1], START_POINT[0], START_POINT[1]);
    path.close();
    ViewAnimator.animate(view).path(path).repeatCount(2).start();
