方法：
private void animTo(View v, float toX, float toY, float duration) {
if (duration < 0) {
return;
}
ObjectAnimator animX = ObjectAnimator.ofFloat(v, "x", toX);
ObjectAnimator animY = ObjectAnimator.ofFloat(v, "y", toY);
AnimatorSet animSet = new AnimatorSet();
animSet.play(animX).with(animY);
animSet.setDuration((long) duration);
animSet.start();
}呼叫：
animTo(lytCool, lytCoolEndX, lytCoolEndY, lytCoolDuration);

uj5u.com熱心網友回復：
animTo(View v, float toX, float toY, float duration)中v不為null，duration恒大于0
