透明动画
//做透明动画,参数1:View,代表你要修改那个控件的属性. 参数2:propertyName代表实现什么样子的动画:"alpha",String类型.
//参数3:float... values,控件修改的参数,new float[]{0.0f, 0.2f, 0.4f, 0.6f, 0.8f, 1.0f}
ObjectAnimator alpha = ObjectAnimator.ofFloat(imageView, "alpha", new float[]{0.0f, 0.2f, 0.4f, 0.6f, 0.8f, 1.0f});
//设置动画执行时长.setDuration
alpha.setDuration(2000);
//设置动画执行的模式setRepeatMode,参数用ObjectAnimator引用.
alpha.setRepeatMode(ObjectAnimator.RESTART);
//设置动画执行的次数.setRepeatCount
alpha.setRepeatCount(1);
//使用ObjectAnimator对象开启动画.
alpha.start();
旋转动画
//做旋转动画,"rotationY".rotationX,rotation new float[]{90f, 180f, 270f, 360f}
ObjectAnimator rotationY = ObjectAnimator.ofFloat(imageView, "rotationY", new float[]{90f, 180f, 270f, 360f});
rotationY.setDuration(2000);
rotationY.setRepeatMode(ObjectAnimator.RESTART);
rotationY.setRepeatCount(1);
rotationY.start();
缩放动画
//做缩放动画,scaleX,scaleY new float[]{1f, 2f, 3f, 4f, 5f, 6f,1f}
ObjectAnimator scaleX = ObjectAnimator.ofFloat(imageView, "scaleX", new float[]{1f, 2f, 3f, 4f, 5f, 6f, 1f});
scaleX.setDuration(2000);
scaleX.setRepeatMode(ObjectAnimator.RESTART);
scaleX.setRepeatCount(1);
scaleX.start();
平移动画
//做平移动画,translationY,translationX new float[]{10f, 20f, 30f, 40f, 60f, 80f}
ObjectAnimator translationY = ObjectAnimator.ofFloat(imageView, "translationY", new float[]{10f, 20f, 30f, 40f, 60f, 80f});
translationY.setDuration(2000);
translationY.setRepeatMode(ObjectAnimator.RESTART);
translationY.setRepeatCount(1);
translationY.start();
动画集合
AnimatorSet set = new AnimatorSet();
ObjectAnimator oa = ObjectAnimator.ofFloat(imageView, "translationX", new float[]{10f, 20f, 30f, 40f, 60f, 80f});
oa.setDuration(3000);
ObjectAnimator oa2 = ObjectAnimator.ofFloat(imageView, "translationY", new float[]{-10f, -20f, -30f, -40f, -60f, -80f});
oa2.setDuration(3000);
set.playTogether(oa, oa2);
set.start();
