Usage

Animate multiple view from one method

ViewAnimator         .animate(image)             .translationY(-1000, 0)             .alpha(0,1)         .andAnimate(text)             .dp().translationX(-20, 0)         .descelerate()         .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();
