ViewPropertyAnimator is a simplified and optimized way to animate properties of a
View has a
ViewPropertyAnimator object available through the
animate() method. You can use that to animate multiple properties at once with a simple call. Every single method of a
ViewPropertyAnimator specifies the target value of a specific parameter that the
ViewPropertyAnimator should animate to.
View exampleView = ...; exampleView.animate() .alpha(0.6f) .translationY(200) .translationXBy(10) .scaleX(1.5f) .setDuration(250) .setInterpolator(new FastOutLinearInInterpolator());
start() on a
ViewPropertyAnimator object is NOT mandatory. If you don't do that you're just letting the platform to handle the starting of the animation in the appropriate time (next animation handling pass). If you actually do that (call
start()) you're making sure the animation is started immediately.
