布局—5个按钮,一个ImageView
平移
private void transAnimator() {
ObjectAnimator objectAnimator = new ObjectAnimator().ofFloat(image,
"translationX", 0f, 200f);
//设置移动时间
objectAnimator.setDuration(2000);
//开始动画
objectAnimator.start();
}
旋转
private void rotateAnimator() {
//创建属性动画,设置移动的方向和偏移量
ObjectAnimator objectAnimator = ObjectAnimator.ofFloat(image, "rotation", 0f, 360f);
//设置移动时间
objectAnimator.setDuration(2000);
//开始动画
objectAnimator.start();
}
缩放
private void zoomAnimator() {
ObjectAnimator objectAnimator = ObjectAnimator.ofFloat(image,
"scaleY", 5f, 5f, 1f);
objectAnimator.setDuration(5000);
objectAnimator.start();
}
渐变
private void gradualAnimator() {
ObjectAnimator objectAnimator = ObjectAnimator.ofFloat(image, "alpha", 0f, 1f);
objectAnimator.setDuration(1000);
objectAnimator.start();
}
组合
private void allAnimator() {
ObjectAnimator objectAnimatorX = ObjectAnimator.ofFloat(image,
"translationX", 0f, 200f);
ObjectAnimator objectAnimatorY = ObjectAnimator.ofFloat(image,
"translationY", 0f, 200f);
ObjectAnimator objectAnimator = ObjectAnimator.ofFloat(image,
"rotation", 0f, 360f);
AnimatorSet animatorSet=new AnimatorSet();
animatorSet.play(objectAnimatorX).with(objectAnimatorY);
animatorSet.play(objectAnimator).after(objectAnimatorX);
animatorSet.setDuration(1000);
animatorSet.start();
}
