ViewAnimator
A fluent Android animation library !
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();
More
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 AndroidViewAnimations and NiftyDialogEffects )
.shake().interpolator(new LinearInterpolator());
.bounceIn().interpolator(new BounceInterpolator());
.flash().repeatCount(4);
.flipHorizontal();
.wave().duration(5000);
.tada();
.pulse();
.standUp();
.swing();
.wobble();
... 
Path animations ( Inspiration from 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(-1).start();
