ValueAnimator

ValueAnimator intAnimator = ValueAnimator.ofInt(200, -100);

intAnimator.addUpdateListener(new AnimatorUpdateListener() {

@Override

public void onAnimationUpdate(ValueAnimator animation) {

Integer animatedValue = (Integer) animation.getAnimatedValue();

view.scrollTo(animatedValue, 0);

}

});

intAnimator.setDuration(DURATION);

intAnimator.start();

下面是浮点型：

ValueAnimator floatAnimator = ValueAnimator.ofFloat(-100.0f, 50.5f);

floatAnimator.addUpdateListener(new AnimatorUpdateListener() {

@Override

public void onAnimationUpdate(ValueAnimator animation) {

Float animatedValue = (Float) animation.getAnimatedValue();

view.scrollTo(0, animatedValue.intValue());

}

});

floatAnimator.setDuration(DURATION);

floatAnimator.start();

传入一个对象：

ValueAnimator argbAnimator = ValueAnimator.ofObject(new ArgbEvaluator(), 0xffffff00, 0x880033ff);

argbAnimator.addUpdateListener(new AnimatorUpdateListener() {

@Override

public void onAnimationUpdate(ValueAnimator animation) {

Integer animatedValue = (Integer) animation.getAnimatedValue();

textView.setBackgroundColor(animatedValue);

}

});

argbAnimator.setDuration(DURATION);

argbAnimator.start();

从一个XML文件获取值

ValueAnimator animator = (ValueAnimator) AnimatorInflater.loadAnimator(ValueAnimatorActivity.this, R.animator.valueanimator);

animator.addUpdateListener(new AnimatorUpdateListener() {

@Override

public void onAnimationUpdate(ValueAnimator animation) {

Integer animatedValue = (Integer) animation.getAnimatedValue();

view.scrollTo(animatedValue, 0);

}

});

animator.start();
