设置一个动画播放这一观点。如果你想立即播放的动画，使用startAnimation这种方法提供了允许细粒度控制的起始时间和失效，

但你必须确保：1）动画开始时间 2）动画应该开始时的观点，将被视为无效。

<span id="result_box" lang="zh-CN"></span>
/**
* Sets the next animation to play for this view.
* If you want the animation to play immediately, use
* startAnimation. This method provides allows fine-grained
* control over the start time and invalidation, but you
* must make sure that 1) the animation has a start time set, and
* 2) the view will be invalidated when the animation is supposed to
* start.
*
* @param animation The next animation, or null.
*/
public void setAnimation(Animation animation) {
mCurrentAnimation = animation;
if (animation != null) {
animation.reset();
}
}

现在开始指定的动画。

/**
* Start the specified animation now.
*
* @param animation the animation to start now
*/
public void startAnimation(Animation animation) {
animation.setStartTime(Animation.START_ON_FIRST_FRAME);
setAnimation(animation);
invalidateParentCaches();
invalidate(true);
}

建议使用

startAnimation来启动动画，setAnimation启动动画是需要条件的
