Android 属性动画ObjectAnimator使用demo,组合动画

//第一个参数:指定执行动画的控件,第二个参数:指定控件的属性,第三个参数是可变长参数 public static ObjectAnimator ofFloat(Object target, String propertyName, float... values)

动画过程监听
animator2.addUpdateListener(new ValueAnimator.AnimatorUpdateListener() { @Override public void onAnimationUpdate(ValueAnimator valueAnimator) { float value = https://www.it610.com/article/(float) valueAnimator.getAnimatedValue(); Log.i("lgq",":ssss====="+value); //动画过程监听 } });

动画状态监听
animator2.addListener(new Animator.AnimatorListener() { @Override public void onAnimationStart(Animator animator) { Log.i("lgq",":ssss===onAnimationStart=111="); }@Override public void onAnimationEnd(Animator animator) { Log.i("lgq",":ssss===onAnimationEnd==222"); animator2.setAutoCancel(false); }@Override public void onAnimationCancel(Animator animator) { Log.i("lgq",":ssss===onAnimationCancel=333="); animator.cancel(); }@Override public void onAnimationRepeat(Animator animator) { Log.i("lgq",":ssss===onAnimationRepeat=444="); } });

动画暂停
animator.pause();

动画重新开始
animator.resume();

动画重复次数
animator2.setRepeatCount(1);

组合动画方法:
AnimatorSet set = new AnimatorSet(); set.play(animator).with(animator3).with(animator2); set.start();

//透明度动画 ObjectAnimator animator = ObjectAnimator.ofFloat(view,"alpha",1,0,1); animator.setDuration(2000); animator.start(); //旋转动画:围绕x轴旋转 ObjectAnimator animator = ObjectAnimator.ofFloat(tv,"rotationX",0,270,0); animator.setDuration(2000); animator.start(); //旋转动画:围绕y轴旋转 ObjectAnimator animator = ObjectAnimator.ofFloat(tv,"rotationY",0,180,0); animator.setDuration(2000); animator.start(); //旋转动画:围绕z轴旋转 ObjectAnimator animator = ObjectAnimator.ofFloat(tv,"rotation",0,270,0); animator.setDuration(2000); animator.start(); //平移动画:在x轴上平移 ObjectAnimator animator = ObjectAnimator.ofFloat(tv, "translationX", 0, 200, -200,0); animator.setDuration(2000); animator.start(); //平移动画:在y轴上平移 ObjectAnimator animator = ObjectAnimator.ofFloat(tv, "translationY", 0, 200, -100,0); animator.setDuration(2000); animator.start(); //缩放动画:在x轴缩放 ObjectAnimator animator = ObjectAnimator.ofFloat(tv, "scaleX", 0, 3, 1); animator.setDuration(2000); animator.start(); //缩放动画:在y轴上缩放 ObjectAnimator animator = ObjectAnimator.ofFloat(tv, "scaleY", 0, 3, 1); animator.setDuration(2000); animator.start();
