属性动画包含:
ObjectAnimator 动画的执行类
ValueAnimator 动画的执行类
AnimatorSet 用于控制一组动画的执行:线性,一起,每个动画的先后执行等。
AnimatorInflater 用户加载属性动画的xml文件
缩放X轴:ScaleX
ObjectAnimator().ofFloat(imageView,”ScaleY”,1.0f,0.0f).setDuration(3000).start();缩放Y轴:ScaleY
ObjectAnimator().ofFloat(imageView,”ScaleX”,1.0f,0.0f).setDuration(3000).start();旋转动画(X轴):rotationX
ObjectAnimator().ofFloat(imageView,”rotationX”,0.0f,360f).setDuration(3000).start();旋转动画(Y轴):rotationY
ObjectAnimator().ofFloat(imageView,”rotationY”,0.0f,360f).setDuration(3000).start();旋转动画(中心点):rotation
ObjectAnimator().ofFloat(imageView,”rotation”,0.0f,360f).setDuration(3000).start();淡入淡出:alpha
ObjectAnimator().ofFloat(imageView,”alpha”,1.0f,0.0f).setDuration(3000).start();位移动画(X轴):
ObjectAnimator().ofFloat(imageView,”translationX”,0.0f,100.0f).setDuration(3000);位移动画(Y轴):
