startoffset:动画执行的时间。
pivotX:缩放(旋转)的中轴点X坐标,距离自身左边缘的位置.
pivoty:缩放(旋转)的中轴点y坐标,距离自身上边缘的位置.
interpolator:速率。

java代码:
ImageView spaceshipImage = (ImageView) findViewById(R.id.spaceshipImage);
Animation hyperspaceJumpAnimation = AnimationUtils.loadAnimation(this, R.anim.hyperspace_jump);
spaceshipImage.startAnimation(hyperspaceJumpAnimation);
Drawable Animation
XML:
<animation-list xmlns:android="http://schemas.android.com/apk/res/android"
android:oneshot="true">
<item android:drawable="@drawable/rocket_thrust1" android:duration="200" />
<item android:drawable="@drawable/rocket_thrust2" android:duration="200" />
<item android:drawable="@drawable/rocket_thrust3" android:duration="200" />
</animation-list>
JAVA:
ImageView rocketImage = (ImageView) findViewById(R.id.rocket_image);
rocketImage.setBackgroundResource(R.drawable.rocket_thrust);
rocketAnimation = (AnimationDrawable) rocketImage.getBackground();
rocketAnimation.start();
ObjectAnimation
最简单的用法:
ObjectAnimator//
.ofFloat(view, "rotationX", 0.0F, 360.0F)//
.setDuration(500)//
.start();
